The Rolling Sonograms

“Hold still and keep your eye shut tight,” I instructed, as I lathered my probe with gel and placed it carefully on my model’s left eye. Having just narrowly escaped the brink of elimination, we were riding a wave of momentum. The trophy was so close we could taste it, but the final round of SonoSlam 2017 was a real-time scan-off on model patients, and our opponents had already proven their skill. Having a live audience didn’t make imaging a pupillary reflex or calculating ejection fraction any easier, and we were feeling the heat.

The day began with scans on rotating stations testing basic knowledge and technique for various organ systems. We struggled with the hepatobiliary station (turns out most teams did over the course of the day; guess we all need more practice) and the physics/knowledge station (I still don’t know how Fourier functions are used to convert sinusoidal data to Cartesian data to produce an image). Still, we put in a strong showing, and at halftime, of 27 teams, 2 of the 3 Ohio State teams placed in the top 5.

Round 2 was trickier but more entertaining than round 1, with stations designed to test our technique and creativity. Among the highlights: identifying an image acquired by a teammate via ultrasound charades, guiding a blindfolded teammate to acquire the correct scan using nothing but verbal cues, and acquiring a biopsy sample under ultrasound guidance. These were difficult, but despite a few groans of frustration, we enjoyed ourselves as we raced through the stations. We felt so good about our performance that we even let ourselves think ahead, speculating whether we would face our teammates in the final. That changed quickly, however, with the announcement of the finalists: we had made the final, but placed third, and were the only OSU team left.

The first challenge of the finals was Dr. Boulger’s favorite ultrasound game, the peel-and-reveal. Tiles filling the screen are removed one by one until someone correctly guesses the image underneath, with more points awarded the more tiles remained. Any hesitation or uncertainty meant more points for the competition, and only the top 2 teams would survive till the second round. Watching the other teams grab an early lead, we sweated bullets as we clawed our way back, only to fall behind again with a premature guess. It was neck-and-neck till the very end, when a gutsy call of McConnell’s sign from Sam edged us into second place. We collapsed back into our chairs in relief, and our attendings, watching from the back, let out their collective breath, probably.

For the final challenge, each team sent a representative to scan on live models behind a closed curtain, with their screens displayed for the audience to see. Each team member had to scan twice, and the audience would vote on the better image by way of cheers and applause. They were also allowed to give advice to the scanners, which meant the auditorium soon became a pandemonium of shouted instructions. Objectives included cardiac output and bladder calculations, MSK ultrasound, and ocular imaging. This time we took the early lead thanks to Charles’ affinity for shoulder scans, but quickly ran into setbacks as well (hard to measure bladder volume when the patient had just peed). We managed to keep up our momentum, however, and after 6 nerve-wracking rounds, we edged our opponents 4-2, clinching the SonoSlam championship for Ohio State for the second time.

Looking back on the day’s events, I am proud of our team’s accomplishments but also impressed with the competition. We have great mentors and almost a decade of ultrasound experience between the 3 of us, but some of the other teams were no less strong, and frankly we were very fortunate to take home the title. To me, this means a bright future for ultrasound education, as medical students across the country are learning valuable skills that will put them in good stead for residency and beyond. More importantly, it means that next year’s teams will have to step up their game, as Ohio State must now defend its title as 2-time SonoSlam champion. No pressure, guys.

Internal Medicine and Bedside Ultrasound–A Match Made in Heaven

I am an internist who does bedside ultrasound. This has not always been true. From 1986, when I got my MD from Johns Hopkins School of Medicine, to November 2011, I was a traditional internist, taking care of a panel of patients in a small university town in Idaho. I saw my patients in the office when they could walk or wheel in with their problems and in the hospital when they were sicker. I took call for my partners on rotating weekends and holidays. I occasionally ordered ultrasounds and echocardiograms and thought of them as blurry representations of internal structures that could be magically interpreted by radiologists.

In 2011, events such as the growing up of our 2 children allowed me to reconsider my choices of what to do with my MD. I had always wanted to do medicine in resource-poor settings overseas. I had often been curious about locum tenens work in other states, which would involve adventure and exposure to new practice styles and surprisingly generous compensation compared to my predominantly outpatient practice. I also had an urge to binge on continuing medical education courses, which I had denied myself for years due to responsibilities at home.

Janice Boughton, MD

One of the CME courses I treated myself to was an introductory course in emergency ultrasound through Harvard/Massachusetts General Hospital. It was wonderfully taught and I was immediately hooked. Ultrasound at the bedside would transform my practice and had the potential to transform the whole practice of internal medicine! The Cupid of bedside ultrasound had sunk his arrow straight between my eyes.

I went on to take more courses in bedside ultrasound both in person and online and bought myself a small pocket ultrasound which rapidly developed my imaging skills. I began to use ultrasound clinically as a diagnostic tool within weeks of my first exposure. I discovered over-expanded bladders, failing hearts, pleural effusions, ascites, or lack thereof in my patients with big bellies. I became a better doctor, and enjoyed my job more. My patients were happy to have benefitted from what looked to them like Star Trek technology.

I expected at any point that someone in the diverse hospitals where I served as a locum tenens hospitalist would ask for my credentials or forbid me to use ultrasound. I expected skepticism by cardiologists with whom I worked. I expected radiologists to be upset at me. I even did a 1-month UC Irvine mini-fellowship and ARDMS certification as a sonographer. These experiences gave me a vast amount more expertise and confidence, but were mostly to ward off imagined disapproval. Yet nobody ever made me present my certification. Nobody disapproved to my face except one radiologist, who I’m still working on. Cardiology consultants were tickled to get imaging information in addition to history and vital signs. I may have benefitted from being in hospitals where people were too busy taking care of patients to fuss with me. It really seemed, though, that the vast majority of people with whom I worked realized that I was a better doctor with an ultrasound than without.

I have gone on to teach bedside ultrasound and participate in research on malaria and schistosomiasis with medical students in Tanzania. I have taught basic ultrasound to overburdened healthcare workers and physicians from Doctors Without Borders in South Sudan during its ongoing civil war. Knowing how to teach basic bedside ultrasound means I am valuable in resource poor settings even if I can only stay for a couple of weeks. I have been able to teach my internal medicine colleagues in the US along with residents and medical students, which has been a wonderful opportunity for a nonacademic rural physician.

So what’s my point here? As an “early adopter” of bedside ultrasound in internal medicine I have made myself a test case. So far these are the results:

  1. It wasn’t too hard to learn enough ultrasound to be a better doctor.
  2. There was never a time when I was too much of a novice to benefit from bedside imaging, yet every time I ultrasound a patient I learn something new. I can’t foresee a time when my learning will be complete.
  3. There has been surprisingly little push-back and a gratifying amount of appreciation.
  4. Bedside ultrasound is the perfect extension of the physical exam in internal medicine. It brought back my joy in physical diagnosis. We should all be doing it!

Obstetric Ultrasound: Tips for Sharing Outcomes With Your Patient

“Are you comfortable? Am I pressing too hard?” I ask my patient these questions to assuage my own concerns and delay the inevitable as I study the ultrasound image of her 20-week-old fetus. Although she says she’s fine, my patient appears expectant and anxious as she, too, searches the black and white image of her unborn child. I wonder, of course, if she sees what I see—a cleft lip and palate.

If you’ve conducted ultrasounds for routine evaluation of your obstetric patients, you know that patients and their partners typically experience a mix of emotions, namely joy and worry, as they await results. You know, too, that delivering positive results is a pleasure as you share in your patient’s happiness and relief. In all likelihood, you also are relieved at escaping the discomfort of delivering bad news to your patient.

Dr and patient

Delivering Abnormal Ultrasound Results

Telling your patient about any pregnancy or fetal abnormality, however common or rare, can be devastating for her, her husband/partner, and her family. After all, every patient wants to know her pregnancy is progressing as expected and her fetus is developing normally. It also can be difficult for you to tell your patient there is a problem. But as a practitioner, you must be prepared to deliver all results, good and bad, to your patients.

A key to delivering abnormal results to your patient includes knowing and using phrases that clearly and honestly apprise your patient of the results without stirring alarm.

Sound easy? It’s not! Even the most seasoned practitioners suggest they never become comfortable giving patients abnormal results.

When results aren’t cause for alarm, patients, especially those in a first pregnancy, still can be highly sensitive to even the slightest aberration. Furthermore, the situation can become complex given varied models for delivering care. For example, when a primary obstetrician sends a patient for scanning at an antenatal testing unit that a maternal-fetal medicine (MFM) specialist oversees, the question is whether the MFM or primary obstetrician should deliver the results. In some cases, patients have scans in emergency departments. What then? Does the radiologist, emergency physician, or primary obstetrician deliver the results?

As an MFM specialist in an antenatal testing unit, I follow my center’s policy to immediately inform patients about their ultrasound results, whatever the outcome. With empirical knowledge to support them, practitioners in my unit know that the longer patients await results, the more likely they are to ruminate, worry, and, in some cases, develop unfounded concerns about their ultrasound results.

With focus on the shared humanity between physician and patient, we treat each patient with careful consideration for her dignity and the compassion we would want for ourselves and our family members.

Once you have told your patient her results, get in touch with her primary obstetrician. In addition to giving the primary obstetrician an opportunity to prepare for a discussion with her/his patient, this approach is integral to delivering high-quality, comprehensive, and continued care.

Follow these tips for delivering abnormal results to your patient:

  • Write down phrases you are comfortable using and practice them with a simulated patient (a family member or friend)
  • Consider how you would feel if you were in the same situation
  • When face to face with your patient, take a moment to gather your thoughts before speaking if necessary
  • Use a calm voice
  • Speak slowly and clearly
  • Look at your patient when talking to her; if her husband/partner is in the exam room, also look at him/her
  • Be straightforward and honest without creating alarm
  • Be sensitive to emotional ques from your patient to pace discussion appropriately. A sobbing patient is unlikely to hear what you’re saying, so wait patiently until she’s ready to listen
  • Ask your patient if she has questions; ask her husband/partner if he/she has questions
  • Answer as many questions as you can; if the patient asks a question you cannot answer on the spot, tell her you will get an answer within the next day
  • Reassure your patient of potential solutions for the situation without making promises
  • Recommend educational material that can help your patient better understand the problem
  • If the problem is genetic in origin, explain the value of genetic counseling before any future pregnancies
  • Take extra time to address your patient’s concerns if necessary
  • Ask your patient if she would like a referral for a counselor so that she can work through feelings about the results
  • Follow up with your patient the next day with a phone call

Telling Your Patient About Ultrasound Results: Practice and Prepare!

All fetal abnormalities on ultrasound, even the most insignificant, are understandably upsetting for parents to be. But being prepared before you break the news can help you and your patients feel more comfortable discussing the situation, including potential outcomes and solutions.

GuptaOne of the privileges of practicing obstetrics in the 2000s is that many of us deliver good news more often than bad news. But this also means that being adept at delivering abnormal ultrasound results requires practice outside as well as inside the office.

How do you deliver bad news to a patient? When do you provide counseling? Comment below or let us know on Twitter: @AIUM_Ultrasound.

Who Has Time to Scan?

image001When I arrived to my shift in the Emergency Department one Thursday, there were 5 unassessed patients on my side with more than 25 in the waiting room, some waiting for hours to be seen. Anyone who works in a busy practice knows the pressure to expeditiously evaluate these patients, and point-of-care ultrasound (POCUS) may be the last thing on your mind.

However, when used properly, POCUS is a time saver. It can lead us to the diagnosis faster, allow for next-step downstream testing, and alert our colleagues in other specialties early that we might need them soon, perhaps even occasionally saving lives.

The excuses to not do an ultrasound are many. How do I fit it into my busy practice? The question is: truly how do I not?

  1. Have the equipment easily accessible.

Searching for an ultrasound machine can be extremely frustrating and a disincentive to using it. No one likes to walk around and search every patient room before you even start to scan.

Because of this, every area should have their designated machine with a home base that is clearly marked and known to everybody. There are additional smart ways to ease this process. We are using a Real Time Location System with RFID technology where equipment is easily located on a tracking board. Other institutions can page an assistant through their EMR to set up the ultrasound in the patient room. Though more cost-intensive, some have chosen to have a wall-mounted machine in every room.

Location board

  1. Bring the machine with you.

Don’t be lazy. There are many patient complaints such as shortness of breath, flank or upper abdominal pain, first trimester bleeding, or eye problems where I am likely going to do an ultrasound study. In these cases, I will bring the machine into the room when first meeting the patient, rather than excuse myself to get it later. Through this, the traditional fragmentation of patient evaluation—ordering a test and waiting for the results—becomes streamlined and sometimes provides the definitive answer immediately.

  1. Rethink your work-flow.

It does not help to bring the ultrasound system with you, if you first need to place an EMR order. Although institution-specific, some have found ways to break up the traditional work-flow (order > worklist > scan), allowing evaluation of patients right away. This requires a discussion with your IT department and administrator but can enable you to rapidly use ultrasound at the bedside.
Also get in the habit of doing an exam the same way every time and maybe set up your machine with predefined labels. You will be surprised how much more efficient you will be and how the quality of your scans will improve with repetition.

  1. Have learners leave the machine in the room.

Our more senior trainees are very versed with ultrasound and usually can get high-quality images without much hands-on direction. If you have learners at different stages, I highly recommend to have them leave the ultrasound machine in the room after completing an exam. You can then review their study right in the room and obtain more views as needed. This avoids setting up the equipment again just for a few additional images.

  1. Keep equipment on the machine.

Having commonly-used supplies on the machine can reduce frustration of going in and out of the room. The most common ultrasound-guided procedure at our facility is IV access. For this reason, we stock the special catheters as well as sterile gel packets on the machine.image003

Recall the last time you weren’t lazy, rolled the ultrasound machine into the room with you and found the ileocolonic intussusception and asked the pediatric radiologist to stay late to do the air contrast enema, or the surgeon to take the patient to the OR with a ruptured abdominal aortic aneurysm (AAA)? Perhaps it was as simple as knowing it was acute cholecystitis and not ordering the contrast CT scan, sparing the young person contrast and radiation. If I can do it on a busy night, so can you.

Should You Include CEUS and Elastography in Your Liver US Practice?

 

Today, the liver is regarded with high importance by our clinical colleagues. The obesity epidemic, with its considerable impact in North America, is associated with severe metabolic disturbances including nonalcoholic fatty liver disease (NAFLD). Further, liver cancer is the only solid organ cancer with an increasing incidence in North America. Where do we as ultrasonographers fit into the imaging scheme to most appropriately deal with these new challenges?

The liver is the largest organ in the body, and certainly the most easily accessed on an abdominal ultrasound (US). It has been the focus of countless publications since the introduction of abdominal ultrasound many decades ago. Exquisite resolution allows for excellent detailed liver evaluation allowing US to play an active role in the study of both focal and diffuse liver disease. Focal liver masses are often incidentally detected on US examinations performed for other reasons and on scans performed on symptomatic patients. Abdominal pain, elevated liver function tests and nonspecific systemic symptoms may all be associated with liver disease. The introduction of color Doppler to abdominal US scanners many years ago elevated the role of US by allowing for improved capability of US to participate in assessment of the hemodynamic function of the liver as well.

malignant tumor ceus

The well-recognized value of abdominal US, including detailed morphologic liver assessment, has made this examination the most frequent study performed in diagnostic imaging departments worldwide. However, in recent years, US has been relegated to an inferior status relative to CT and MR scan, as their use of intravenous contrast agents has made them the corner stone modalities for virtually all imaging related to the presence of focal liver masses. As we now live in an era of noninvasive diagnosis of focal liver disease, greyscale US has fallen out of favor, as it is nonspecific for liver mass diagnosis. While US is the recommended modality for surveillance scans in those at risk for development of hepatocellular carcinoma, today, all identified nodules are then investigated further with contrast-enhanced CT and/or MR scan.

In the more recent past, US has been augmented by 2 incredible noninvasive biomarkers: elastography, which measures tissue stiffness, and contrast-enhanced ultrasound, which shows perfusion to the microvascular level for the first time possible with US. These noninvasive additions are invaluable and their adoption in routine US practices may allow the reemergence of US as a major player in the field of liver imaging.

Most conventional US machines today are equipped with the capability to perform elastography, especially with point shear wave techniques (pSWE). In pSWE, an ARFI pulse is used to generate shear waves in the liver in a small (approximately 1 cm3) ROI. B mode imaging is used to monitor the displacement of liver tissue due to the shear waves. From the displacements monitored over time at different locations from the ARFI pulse, the shear wave speed is calculated in meters per second, with higher velocities associating with increased tissue stiffness. The accuracy for the determination of liver fibrosis and cirrhosis with pSWE as compared with gold standard liver biopsy, is now undisputable. Because of the great significance of liver fibrosis secondary to fatty liver and the obesity epidemic, the development of this technique as a routinely available study is essential. Because of the frequent selection of US as the first test chosen for any patient suspect to have undiagnosed diffuse liver disease, the opportunity for elastography to be included with the diagnostic morphologic US test should be developed as a routine.

Contrast-enhanced US (CEUS), similarly, is available on most currently available mid- and high-range US systems, allowing for nondestructive low MI techniques to image tumor and liver vascularity following the injection of microbubble contrast agents for US. This allows for a similar algorithmic approach to contrast-enhanced CT and MR scan for noninvasive diagnosis of focal liver masses. CEUS additionally offers unique imaging benefits that include no requirement for ionizing radiation and also imaging without risk of nephrotixity, invaluable in the many patients who present for imaging with high creatinine, preventing injection of both CT and MR contrast agents.

Incorporation of pSWE and CEUS into standard liver US in patients with suspect diffuse or focal liver disease is a cost-effective and highly appropriate consideration as this is readily available, performed without ionizing radiation, and at a considerable cost saving over all other choices.

Can you diagnose a hepatocellular carcinoma or other liver tumor with CEUS?  And, can you determine if a liver is cirrhotic or not?  With the addition of pSWE and CEUS to your liver US capability, yes, you can.

Excellence in Education

It is an honor to receive the 2017 Peter H. Arger, MD, Excellence in Medical Student Education Award. I am fortunate to know Dr. Arger and recognize his remarkable achievements in education, accreditation, and leadership in ultrasound. It’s my great privilege to work with different students, whether they are medical students, residents, fellows, sonography students, vascular technology students, or physicians of different medical specialties. I have had many great teachers and mentors toJohn_Pellerito learn from. Some of my favorite teachers like Barry Goldberg, Ken Taylor, Chris Merritt, and Peter Arger have the gift to communicate complex ideas and make them simple and easy to understand. Teachers at that level inspire me to be the best I can be.

I know there are many educators who understand that feeling when a student “gets it.” The anatomy and physiology that they’ve been studying comes to life. When the ultrasound unit is no longer a confusing mess of dials and buttons and becomes a window into the human body. When they realize that in their hands, ultrasound can make a difference in patient care.

I am lucky to work with  a team of physicians and sonographers who enjoy teaching our medical students. We meet to devise new ways to integrate ultrasound into our longitudinal 4-year ultrasound program. One of the techniques we use to engage our students is to integrate games into our classes. Our SONICS (SONographic Integration of Clinical skills and Structure) faculty has enjoyed putting together ultrasound games for our students. We find that gaming increases their excitement and takes advantage of their competitive edge. One of our latest creations, the Hunger Games (J Ultrasound Med 2017; 36:361–365), has proven very successful.

During this class, we ask one member of each student team to fast prior to a scan of the gallbladder and mesenteric arteries. Following a breakfast of a bagel and cream cheese, the students are rescanned to assess for changes in gallbladder size and mesenteric blood flow. All scanning is performed by the students with faculty guidance. One team is deemed the “winner” and awards are given. The session combines both anatomic and physiologic principles to learn about gastrointestinal and vascular function and incorporate Doppler techniques. This activity provides the foundation for a powerful integration of Doppler ultrasound into medical education.

What are some of the ways that you have engaged your students with fun and interactive ultrasound programs? Do you have any stories from your own education to share? Comment below or let us know on Twitter: @AIUM_Ultrasound.

SonoSlam 2017

16SonoSlam_logoIf you attended the AIUM convention the past 2 years you may have heard mention of SonoSlam in passing. So what is it? SonoSlam is a medical student ultrasound competition and educational event. It was conceived as an idea to promote medical student ultrasound and was officially born in Orlando in 2015. A few members of the medical education committee were discussing how to get students more engaged in ultrasound at the national level. A national ultrasound student interest group had been formed and got behind the idea of nationalizing ultrasound activities for medical students. Many of us had been involved in regional events such as Ultrafest or had participated in Sonogames™, an emergency medicine resident ultrasound competition. As we brainstormed, SonoSlam came to fruition. We wanted this event to be more than a game, making sure to integrate education into the proceedings. Given the diversity of exposure to ultrasound in undergraduate medical education, the faculty wanted to ensure that this event would be appealing to students of all levels of experience. In addition, the unique offering of AIUM is that this event would be multidisciplinary. With these key components of education, competition, and a multidisciplinary approach SonoSlam was created. The inaugural SonoSlam was held in New York in 2016 with the winning team awarded the Peter Arger Cup, named after the famed radiologist who championed medical student ultrasound education at the AIUM. Seventeen teams from 12 different schools participated in this inaugural event with more than 30 faculty from across the country. This year in Orlando we grew to 23 teams from 17 schools from across the country—Oregon to New York to Florida and all in between. We had more than 50 faculty from a multitude of specialties, including emergency medicine, internal medicine, critical care, obstetrics and gynecology, radiology, and pediatrics. We plan to continue to host this event annually with the lofty goal of having representation from every medical school in the country. We hope to see you in New York March 24, 2018!
