About four years ago, I felt like I had made a massive discovery akin to cracking cold fusion or inventing time travel. Although my revelation didn’t win me a Nobel Peace Prize, it forever changed the course of my medical training and gynecology practice. This discovery came through a podcast on Advanced Imaging for Endometriosis. Thus, my journey into the world of advanced gynecologic ultrasound (AGU) and endometriosis began.

The title and details of the mentioned podcast, "Advanced Imaging for Endometriosis" on the Gynecologic Surgeons Unscrubbed podcast dated Tuesday, Mar 23, 2021. The description states, "In this episode, Dr. Cara King speaks with Dr. Mathew Leonardi, an advanced gynecologic surgeon and sonologist (ultrasound specialist) at McMaster University Medical Centre in Hamilton, Canada. As March is Endometriosis awareness month, Mathew talks about advanced endometriosis imagery and how it impacts preoperative counseling, planning, and intraoperative surgical intervention. He also talks about how he created his own path to where he is today. Listen as he shares how to build skills in advance sonography and incorporate this into residency as well as fellowship education."

My years of medical school and residency training had never included this kind of diagnostic capability for endometriosis. The axiom that surgery was how endometriosis was diagnosed was firmly established in my mind. Furthermore, I was astonished that ultrasound, something so ubiquitous in obstetrics and gynecology, was the way to achieve this paradigm shift. I remember sitting in my car listening to Dr. Mathew Leonardi talk about the possibility of not just diagnosing endometriosis before surgery but specifically mapping out where the disease was present. My mind was blown. In my new-found passion for endometriosis diagnosis, I took to the internet.

After a brief exchange on Twitter, Dr. Leonardi graciously agreed to let me shadow his practice for a week. Fortunately for me, Hamilton, Ontario, where Dr. Leonardi worked, was just a short drive and a (sometimes) quick border crossing from where I was completing a residency in Buffalo, New York, so I could witness these transformative ultrasound techniques firsthand. What I experienced that week was a game-changing way to care for patients. Patients with pelvic pain and suspected endometriosis could visit the clinic, undergo a comprehensive pelvic ultrasound, and receive an informed management plan. It wasn’t a model of “let’s see what we find” or broad counseling about options. Patients received immediate information about the scan findings and knew what to expect in the management plan. Furthermore, the therapeutic benefit here cannot be understated. Many patients would tear up feeling validated as their experiences were finally reflected in tangible scan results.

Of course, I was impressed by the patient experience side of AGU. What hooked me even further was the amazing amount of information that one could garner from these ultrasound techniques. Cul-de-sac obliteration, deep endometriosis of the bowel, ureteral strictures, uterosacral ligament lesions, ovarian mobility, and the list goes on. With the wealth of information accessible through ultrasound and my sights set on a surgical practice, I had to learn this transformative skill. A few years later, while in my minimally invasive gynecologic surgery fellowship, I was fortunate to be able to travel to McMaster University and complete a month-long elective with Dr. Leonardi to develop my AGU skills. While this experience greatly advanced my ultrasound capabilities, I believe that anyone interested in AGU does not necessarily need a dedicated month of intensive scanning to bring this skill into practice. The journey starts with a single scan.

Ultrasound imaging is a cornerstone of care in high-risk pregnancies, providing essential insights into both maternal and fetal well-being and structural development. But who ensures that these images are not only accurate but also of diagnostic quality, capturing even the smallest details?

A maternal-fetal medicine (MFM) sonographer.

MFM sonographers are the unsung heroes of prenatal imaging, acting as the eyes of Maternal-Fetal Medicine specialists. Imagine being the first to see a tiny heartbeat on the screen of a patient with a history of multiple losses or detecting a complication early enough to save a baby’s life—that’s the kind of impact MFM sonographers have every day. Their expertise goes beyond basic imaging, making their role indispensable in managing high-risk pregnancies.

So, what sets MFM sonographers apart? Their training and skills are specialized and essential to optimizing prenatal care and improving outcomes. Below are some key aspects of their work that demonstrate their unique contributions.

Expertise in Complex Obstetric Cases

MFM sonographers specialize in handling challenging and high-risk pregnancies. These may involve conditions such as congenital anomalies that require detailed anatomical assessment, multiple gestations, where each fetus must be carefully monitored for growth and complications, and maternal health conditions like preeclampsia, diabetes, or autoimmune disorders, which can impact fetal development.

Take, for example, a case where a mother presents for a late anatomy at 32 weeks. The sonographer notices vessels near the lower uterine segment with color Doppler and decides to perform transvaginal imaging to get an optimal view. The transvaginal imaging demonstrates cord vessels crossing the cervix, which is consistent with vasa previa. The sonographer’s detection of vasa previa prompts immediate medical intervention, preventing delivery complications.

With their unique skillset, MFM sonographers can identify and recognize sonographic findings or complications early on. Their ability to provide comprehensive imaging enables Maternal-Fetal Medicine Specialists to make timely, critical decisions affecting both short-term and long-term outcomes for mother and baby.

Specialized Examinations and Advanced Imaging Techniques

In high-risk obstetrics, standard imaging alone may not be sufficient to capture the whole picture. MFM sonographers develop proficiency in various specialized examinations and advanced imaging techniques. Some examples below:

  • Doppler studies to evaluate blood flow in key vessels, such as the umbilical artery, middle cerebral artery, ductus venosus, and maternal vessels, too! (Figure 1.)
Figure 1. Doppler ultrasound.
  • Fetal echocardiography to assesses complex cardiac structures and detect congenital heart defects. (Figure 2.)
Figure 2. Fetal echocardiography.
  • Fetal neurosonography focuses on detailed imaging of the fetal brain and central nervous system. (Figure 3.)

Beyond the Image: Critical Thinking in High-Risk Obstetrics

MFM sonographers must possess strong critical thinking skills to adapt to complex obstetric cases’ dynamic and often unpredictable nature. Each scan involves real-time assessment and decision-making. Sonographers must quickly discern between normal and abnormal findings, usually flagging fetal structural anomalies that may require further imaging or immediate intervention. High-risk pregnancies frequently demand deviations from standard imaging protocols, prompting sonographers to use their judgment to determine which additional views or techniques—such as Doppler studies or 3D imaging—are necessary to obtain a complete and accurate assessment. In urgent situations, such as fetal distress or signs of preterm labor, sonographers must prioritize findings and swiftly communicate critical information to the maternal-fetal medicine specialist to facilitate immediate action. These cognitive skills are essential for delivering comprehensive, high-quality imaging that enables timely and accurate diagnoses, ultimately contributing to improved outcomes for mothers and babies.

Becoming an MFM Sonographer: What You Need to Know

Sonographers typically begin their careers by obtaining Registered Diagnostic Medical Sonographer (RDMS) credentials with a specialty certification in Obstetrics & Gynecology (OB/GYN), followed by clinical experience in obstetric imaging. The more experience you gain in performing obstetric and gynecologic imaging, the better prepared you will be. Those who pursue a career in maternal-fetal medicine (MFM) undergo additional training to develop proficiency in high-risk obstetric imaging. Many also pursue advanced certifications, such as fetal echocardiography, to further validate their skills in this specialized field. The role requires a combination of technical proficiency, critical thinking, adaptability, and a commitment to continuous learning to stay current with advancements in ultrasound technology and best practices.

A career in maternal-fetal medicine (MFM) sonography is both rewarding and impactful, offering opportunities to make a real difference in the lives of mothers and babies. Sonographers play a pivotal role in high-risk pregnancies, often being the first to detect critical conditions that can change the course of care. Beyond the emotional rewards, the field also offers career growth opportunities. With advancements in ultrasound technology and an increasing focus on women’s health, MFM sonographers can pursue advanced roles as educators, advanced practice sonographers, or administrative leaders, allowing them to expand their expertise and advance their careers. For many, the opportunity to combine cutting-edge science with compassionate care makes this profession impactful and fulfilling.

The clinical applications for diagnostic ultrasound have expanded tremendously since its introduction in the late 1950s thanks to technological advancements in both hardware and software, enabling rapid diagnoses at the patient bedside. With this expansion, the medical specialties employing ultrasound as a diagnostic tool have also increased substantially, resulting in a consistently growing group of new users across all levels of medical training and practice.

Ultrasound has long been understood as a low-cost, portable, and ionizing radiation-free imaging method, which has, in part, fueled this rapid expansion. However, ultrasound is ultimately a type of mechanical energy that is able to penetrate tissue, yielding the potential for bioeffects. Practically, the potential for bioeffects is measured through the thermal index (TI) and mechanical index (MI), which provide indicators of the temperature elevation and likelihood of cavitation, respectively, at a particular scan setting. While there have been no independently confirmed adverse effects in humans caused by current diagnostic instruments without contrast agents, biological effects have been reported in pre-clinical mammalian systems, emphasizing the importance of proper clinical use. As diagnostic ultrasound expands to new users and clinical applications, it is imperative that we continue to understand and assess these potential bioeffects and educate new ultrasound users to continue to use ultrasound safely.

The AIUM bioeffects committee has long undertaken this task, examining emerging technologies and making recommendations based on findings. Recently, the bioeffects committee updated its statement on the “Prudent Clinical Use and Safety of Diagnostic Ultrasound”. This statement reaffirms the promise of ultrasound as a safe and effective tool for diagnostic imaging when used properly by qualified health professionals.

Specifically, we emphasize three main ways to ensure diagnostic ultrasound is used safely:

  1. Monitor acoustic outputs—The likelihood of bioeffects can increase by increasing acoustic outputs, indicated by the thermal and mechanical indices. Exposure time should also be monitored, as increased exposure time can also increase the likelihood of bioeffects.
  2. Follow the ALARA principle—The as low as reasonably achievable (ALARA) principle maintains that users employ the lowest acoustic output and shortest scanning time to reasonably achieve diagnostic-quality images.
  3. Only allow qualified professionals to use ultrasound—Ultrasound should be used only by qualified health professionals to provide medical benefit to the patient.

As new diagnostic ultrasound technologies are developed and evaluated, it will continue to be critical to ensure new users understand the proper use of diagnostic ultrasound and the potential for bioeffects, particularly as the use of ultrasound expands beyond traditional use cases and into the future—perhaps even one day into the home!

A “Hands-Off” Approach to Teaching Ultrasound Image Acquisition

Posted on by

Traditionally, ultrasound (US) scanning has been considered a hands-on skill requiring in-person training. However, there are numerous situations in which such training is not feasible. The COVID-19 pandemic highlighted the necessity of occasionally limiting exposure to patients, faculty, and staff, prompting a shift toward remote learning. Additional factors, such as patient inability to attend in-person appointments, resource limitations, and an imbalance between the number of learners and clinical opportunities, further underscore the need for innovative teaching methods. In global health settings, geographic barriers sometimes prevent instructors from providing in-person training, making remote solutions indispensable.

Despite these challenges, tele-ultrasound (tele-US) teaching presents unique opportunities to bridge the gap. Yet, one major obstacle remains: teaching image acquisition. As noted in the literature, image acquisition during tele-US instruction is a key difficulty. Challenges include explaining transducer manipulation without instructors’ physical presence, as well as accounting for variables like transducer position, transducer angles, patient positioning, and breathing. These concerns have been documented by Recker et al. in their review of ultrasound in telemedicine (Recker F, Höhne E, Damjanovic D, Schäfer VS. “Ultrasound in Telemedicine: A Brief Overview.” Applied Sciences. 2022; 12(3):958. https://doi.org/10.3390/app12030958).

Interestingly, some studies suggest that tele-US training can achieve comparable outcomes to in-person methods. Research by Soni et al. during the COVID-19 pandemic found no significant difference in post-test knowledge between tele-US and in-person training groups (Soni, Nilam J., et al. “Comparison of In-Person versus Tele-Ultrasound Point-of-Care Ultrasound Training during the COVID-19 Pandemic.” The Ultrasound Journal. 2021; 13;article 39. https://link.springer.com/article/10.1186/s13089-021-00242-6). Faculty expressed frustration with the inability to physically demonstrate transducer control. The barriers cited by faculty were echoed in a study by Schroeder et al., which addressed the challenges of teaching sports ultrasound remotely during the pandemic (Schroeder AN, Hall MM, Kruse RC. “Sports Ultrasound Training During a Pandemic: Developing a “Hands-on” Skill Through Distance Learning.” Am J Phys Med Rehabil. 2020; 99(9):860–862. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7363391/). Interestingly though, in Soni’s study, learners often preferred troubleshooting their own images without physical intervention. This finding suggests that “hands-off” instruction might foster autonomy and deeper learning.

Adopting a “hands-off” approach to teaching ultrasound image acquisition is not only possible but can also be highly effective. This method involves avoiding direct contact with the transducer after an initial demonstration, and instead guiding learners through verbal instructions. Many learners find this approach advantageous, as it empowers them to develop their transducer manipulation skills independently. For instructors, the key lies in shifting focus from “What is the probe doing?” to “What is the image doing?”. To teach image acquisition without physical guidance, break the question “What is the image doing?” into manageable components:

  • Is the near field moving?
  • Is the far field moving?
  • Are you moving through a structure (x-axis), or is the structure moving in relation to the leading edge (y-axis)?

Use the following images to further understand these concepts:

By analyzing these aspects, instructors can provide precise feedback and help learners make necessary adjustments. This technique is versatile and can be applied in both in-person and remote settings. It is particularly useful during retrospective image reviews, where instructors can guide learners in interpreting images and refining their transducer manipulation skills.

The “hands-off” teaching method not only adapts to the constraints of remote learning but also encourages learners to develop critical thinking and self-sufficiency. By practicing this approach, instructors can enhance their ability to guide students effectively, even in challenging circumstances. Whether teaching remotely or in person, this method offers a valuable framework for ultrasound education. Try it with your learners today!

Artificial Intelligence (AI) is transforming ultrasound imaging by automating complex tasks and enhancing diagnostic accuracy. In 2025, we expect AI to play a central role in streamlining workflows.

AI algorithms are increasingly capable of analyzing ultrasound images to detect and measure abnormalities, such as tumors, cysts, or cardiovascular issues, with speed and precision. These systems can assist practitioners in diagnosing conditions at an earlier state, reducing the risk of misdiagnosis. Moreover, real-time AI guidance is being integrated into portable devices, making it easier for clinicians to perform and interpret scans in remote or underserved areas.

For example, machine learning models are being trained to help ultrasound practitioners evaluate fetal development, monitor chronic diseases, and even predict patient outcomes. As these tools become more accessible, AI-driven ultrasound diagnostics will help address global disparities in healthcare delivery.

2. Therapeutic Ultrasound

Beyond diagnostics, ultrasound is increasingly being used for therapeutic purposes. Therapeutic ultrasound employs high-intensity sound waves to treat a variety of medical conditions by delivering targeted energy to tissues.

Applications of therapeutic ultrasound include treating kidney stones, fibroid, and prostate disease, as well as enhancing drug delivery and alleviating chronic pain. Focused ultrasound therapy is also making significant strides in oncology. It’s used to ablate tumors non-invasively using either thermal or mechanical effects and the latter has been found to also promote abscopal immune responses. Additionally, this technology is showing promise in neurology, with research exploring its potential to treat conditions like Parkinson’s disease, addiction, and depression by stimulating specific areas of the brain.

As the technology continues to advance, therapeutic ultrasound offers a noninvasive alternative to traditional surgical procedures, reducing recovery times and minimizing risks. In 2025, look out for this application as it gains more widespread adoption in both clinical and research settings.

3. Miniaturization and Portability

Portability is becoming a common feature of next-generation ultrasound devices. Compact and lightweight handheld units are set to become even more powerful in 2025, enabling point-of-care imaging in ways that were unimaginable just a decade ago.

These miniaturized devices are equipped with wireless capabilities, allowing clinicians to transmit data seamlessly to cloud-based platforms or electronic health records (EHRs). In emergency situations, paramedics and first responders can use portable ultrasound to assess internal injuries on-site, significantly improving patient outcomes.

Additionally, this trend aligns with the growing focus on telemedicine. Patients in remote or rural areas can now benefit from real-time imaging performed by trained technologists and reviewed by specialists miles away.

4. High-Resolution 3D and 4D Imaging

The demand for high-resolution imaging is pushing the boundaries of 3D and 4D ultrasound technology. By 2025, these systems will deliver clearer, more detailed images, providing clinicians with enhanced diagnostic capabilities.

4D ultrasound, which adds the dimension of time to 3D imaging, is especially beneficial in fields like obstetrics, where it offers real-time visualization of fetal movements. Beyond obstetrics, high-resolution imaging is proving invaluable in cardiology and oncology, enabling practitioners to visualize complex structures such as heart valves or tumor margins with greater clarity. This technology also bridges the gap and allows for greater reliability of mutual registration between ultrasound and MRI, CT, and PET.  

Image resolution improvements are accompanied by generally more affordable ultrasound technology overall, making sonography a first radiologic assessment tool accessible to smaller clinics and facilities worldwide.

5. Integration With Wearable Technologies

Wearable devices are stepping into the ultrasound space, promising to revolutionize how and where imaging is conducted. These devices, which can be worn as patches or integrated into clothing, are designed to provide continuous monitoring of specific conditions.

In 2025, you may see wearable ultrasound being used for applications like tracking cardiovascular health or monitoring chronic conditions such as kidney disease. For instance, a wearable device could continuously measure blood flow or detect abnormalities in real time, alerting healthcare providers to intervene in a timely manner.

This trend aligns with the broader movement towards personalized medicine, where patients take a proactive role in their healthcare with the help of smart technologies.

6. Expanded Use of Contrast-Enhanced Ultrasound (CEUS)

Contrast-enhanced ultrasound (CEUS) is gaining traction for its ability to improve visualization of blood flow and tissue vascularity. Unlike traditional ultrasound, CEUS uses microbubble contrast agents that provide detailed imaging without exposing patients to ionizing radiation or iodinated contrast material.

In 2025, CEUS is expected to find broader applications, particularly in oncology and cardiology. It is being used to assess heart function more accurately, differentiate between benign and malignant lesions, monitor the efficacy of cancer treatments, and has therapeutic applications. The latter is a unique demonstration of ultrasound having both diagnostic and therapeutic indications. 

The noninvasive nature of CEUS, combined with its diagnostic precision, is making it a preferred option for patients and providers alike. As regulatory approvals expand and more clinicians are trained to use this technology, CEUS will likely become a standard in advanced diagnostic imaging.

Conclusion

Ultrasound technology is undergoing a renaissance, driven by advances in electronics, miniaturization, portability, and imaging algorithms, including AI. As we move into 2025, these trends are set to enhance diagnostic capabilities, improve patient outcomes, and make imaging more accessible than ever before.

For healthcare providers and institutions, staying ahead of these trends will be critical in delivering cutting-edge care. Whether through adopting AI-powered solutions or CEUS, integrating wearable devices, or exploring new techniques like therapeutic ultrasound, the future of ultrasound is brighter—and more innovative—than ever.

The Dawn of Large Language Models (LLMs) in Ultrasound

With the advent of large language models (LLMs), such as the well-known ChatGPT, there has been a surge of interest in how to leverage these technologies in healthcare. These queries are far from baseless, as LLMs have already demonstrated significant value in various non-clinical fields. It is entirely reasonable to explore their potential in medical imaging. The biomedical industry has begun to innovate and propose solutions based on the perceived needs of physicians and the medical imaging workforce, often from an engineering standpoint. However, LLMs offer a unique opportunity to develop solutions through a collaborative approach that includes both physicians and industry professionals.

In other words, only by integrating insights from clinicians can we ensure that the benefits of LLMs are realized in ways that genuinely enhance clinical practice. This collaborative approach is particularly relevant in the field of ultrasound imaging, where the unique real-time nature of the modality, combined with operator-dependent variability, presents both opportunities and challenges. This blog post explores the exciting possibilities of LLMs in ultrasound imaging through two specific approaches: scan-time AI assistance and review-time AI assistance.

The Dream: Scan-Time AI by Real-Time Integration of LLMs

Imagine having a smart assistant right by your side during an ultrasound exam, processing data in real time and offering insights instantaneously. This “scan-time AI” is not a distant dream but an emerging reality. By integrating LLMs into ultrasound machines, clinicians can receive immediate feedback on the screen. This AI-powered assistance can highlight areas of interest, suggest potential diagnoses, and recommend additional views or techniques to optimize image quality, making the diagnostic process more accurate and efficient.

However, the journey to seamless real-time AI integration comes with its own set of challenges. The primary hurdle is ensuring that the AI operates with split-second precision, as any lag could disrupt the examination flow. Additionally, the integration must be intuitive, ensuring that AI suggestions complement the clinician’s expertise without causing distraction. The ultimate goal is to create a harmonious partnership where AI augments the clinician’s skills and enhances patient care.

As their name implies, LLMs are designed to communicate with language at the center. Early examples include chat-like communication with the user, which, at first glance, may not seem viable for medical imaging workflows. However, LLM literature is advancing very rapidly, and with the invention of multi-modal LLMs, communication with ultrasound systems will no longer be limited to text but also extend to other modalities such as voice and images. Voice commands can streamline the process, allowing clinicians to focus on the patient and the probe without needing to manipulate controls manually. For instance, a clinician could say, “Compare the thickness of the renal cortex with the medulla” and the ultrasound machine would reason through the command, detect the said anatomical structures, perform the measurement, and display the results, thus improving efficiency and ergonomics. However, voice interaction in a clinical environment brings its own set of complexities. The bustling background noise, the need for precise and unambiguous commands, and the potential for AI misinterpretation are significant factors to consider. Furthermore, voice interaction must be evaluated for its impact on privacy within the clinical setting. When these issues with voice communication in clinical settings are addressed, using LLMs through voice commands for ultrasound examinations will become much smoother and more efficient.

We’re There: Review-Time AI for Post-Examination Analysis

While real-time AI offers immediate benefits during the scan, “review-time AI” focuses on the critical post-scan phase. LLMs can meticulously review ultrasound images and generate detailed reports, highlighting key findings and suggesting differential diagnoses. This application can significantly alleviate the documentation burden on clinicians, allowing them to dedicate more time to patient care.

The necessity for LLMs in review-time AI stems from the sheer volume and complexity of data clinicians must analyze. By automating the initial review and providing structured reports, LLMs enhance the consistency and quality of ultrasound interpretations. This approach also facilitates collaborative care, as AI-generated reports can be easily shared and reviewed by other specialists, ensuring a comprehensive evaluation of the patient’s condition.

A Call to Action for Physicians

Physicians play a pivotal role in shaping the future of AI technologies. While engineers and data scientists provide the technical backbone, clinicians’ insights and feedback are crucial in developing AI systems that truly address healthcare needs. Physicians are encouraged to experiment with these new-age AI tools in their daily routines, providing critical feedback that will steer the evolution of AI in a direction that genuinely enhances clinical practice.

Integrating LLMs into ultrasound imaging is not merely a technological advancement but a paradigm shift that requires active collaboration between clinicians and technologists. By exploring the exciting possibilities of scan-time and review-time AI and addressing the challenges of voice interaction, we can pave the way for a more efficient and accurate diagnostic process. Physicians, your involvement and insights are crucial. Together, we can shape a future where AI not only complements but also elevates the art and science of ultrasound imaging. Let’s embrace this transformative journey and lead the way to a new era of medical innovation.
