When one considers the variety of responsibilities of an on-site magnetic resonance imaging (MRI) technologist, Emanuel Kanal, M.D., noted in a 

 that the availability of a remote MRI technologist actually may enhance MRI safety.

“Who today is in charge of overseeing that adverse event? The technologist. … Who is responsible for screening the patient? The technologist. Who is responsible for injecting them? The technologist. Who is responsible for answering the phones? The technologist,” noted Dr. Kanal, the chief of the Division of Emergency Radiology and director of Magnetic Resonance Services with the University of Pittsburgh Medical Center in Pittsburgh, Pa.

“ … In so many of our sites, the MR technologist is the only line of defense. They do everything. We hold them responsible for every single thing that has to do with safety in that environment. And for the first time, we just gave them an assistant.”

Tobias Gilk, MRSO, MRSE, added that clearly defined roles for the remote MRI technician and the on-site individual working with the patient may “reduce the frequency and severity” of adverse events.

“Whether it's an adverse reaction to contrast, whether it's a projectile event, whether it's a quench, in all of those situations, we're essentially in clean-up mode, right? I think one of the things that's really interesting is the potential that by actively managing patients and screening and the physical environment, as Dr. Kanal was describing, with specialization right, one individual is specialized to operating the scanner safely and effectively, and one individual is specialized in managing the environment and the individuals who operate within it,” noted Gilk, the founder of Gilk Radiology Consultants, a senior vice president of RADIOLOGY-Planning, and a board member of the American Board of Magnetic Resonance Safety (ABMRS).

While emphasizing the importance of site-specific standard operating procedures (SOPs) with remote magnetic resonance imaging (MRI) safety, Emanuel Kanal, M.D., said on a 

 that it is critical to define will be stepping into the shoes and role of the traditionally on-site MRI technologist.

“The most knowledgeable person about MR safety in general is the MR technologist. They're worth their weight in gold. They're the ones that that guard the site. They oversee the site. They protect the patient, health-care practitioners, the site itself and their interests. They're the most knowledgeable, almost across the board, and they've been removed from the site,” pointed out Dr. Kanal, chief of the Division of Emergency Radiology and director of Magnetic Resonance Services with the University of Pittsburgh Medical Center in Pittsburgh, Pa.

“ … Now we’re facing the situation with the full remote operation clinical scanning … which is really going to necessitate that we figure out who that person is, what training or competencies we expect that person to have, how that new person plugs into a workflow, and as Dr. Kanal described, situational responsibility (and) situational authority in that environment,” added Tobias Gilk, the founder of Gilk Radiology Consultants, a senior vice president of RADIOLOGY-Planning, and a board member of the American Board of Magnetic Resonance Safety (ABMRS).

Dr. Kanal added that remote MRI scanning currently isn’t addressed in the Manual on MR Safety from the American College of Radiology (ACR). However, Dr. Kanal noted there will a section on remote MRI safety at the upcoming Radiological Society of North America (RSNA) conference (Nov. 30-Dec. 4, 2025) that he will be moderating as well as forthcoming announcements from the ABMRS.

While Marfan syndrome is a clinical diagnosis, Alan C. Braverman, M.D., FACC, noted in a recent interview that radiologists play an “invaluable” role in facilitating early diagnosis of this genetic aortic condition.

“They can be the first to put the words into a clinician's mind that this condition that they're seeing on imaging could be something much more,” emphasized Dr. Braverman, the director of the Marfan Syndrome and Aortopathy Center at the Washington University School of Medicine in St. Louis, Mo.

“When there are combinations of findings — root aneurysm, tortuous arteries, mitral valve prolapse — when these features are seen on an imaging study, not just reporting them in diameters accurately, but also suggesting the possibility of something more, like Marfan syndrome or some genetic aortic condition when unexplained in a young person, in particular, can be so helpful to the clinician. It's invaluable.”

For patients with Marfan syndrome, Dr. Braverman emphasized complete assessment of the proximal aorta. Noting that an enlarged aortic root is common in this patient population, Dr. Braverman said the diameter of the aortic root generally exceeds 40 millimeters in younger male patients and 37 millimeters in younger female patients.

While these findings can be visualized very well on echocardiogram, cross-sectional imaging with computed tomography angiography (CTA) or magnetic resonance angiography (MRA) are recommended for initial diagnosis in adult patients and can aid in differentiating between Marfan syndrome and other conditions, such as Loeys-Dietz syndrome, noted Dr. Braverman, a professor of medicine and alumni endowed professor of cardiovascular diseases at the University of Washington School of Medicine.

Pertinent Insights into the Imaging of Patients with Marfan Syndrome

Emphasizing the role of radiologists in facilitating timely diagnosis of Marfan syndrome, Alan Braverman, M.D. discussed the use of echocardiography, CT, and MRI in evaluating patients with this genetic aortic condition.

When evaluating an artificial intelligence (AI) model for initial assessment of left ventricular ejection fraction (LVEF) on echocardiograms, David Ouyang, M.D., said he was genuinely surprised that cardiologists had greater confidence in initial AI assessments than those provided by cardiac sonographers with an average of 14.1 years of experience.

In the randomized trial, recently published in 

, cardiologists revised 27.2 percent of initial LVEF assessments by sonographers in comparison to 16.8 percent of AI assessments.

“We initially thought of the tool as kind of a streamlining tool where it speeds things up. We actually designed the trial as a non-inferior trial. We weren’t expecting AI to be better than sonographers. Hopefully, it would be equivalent,” noted Dr. Ouyang, who is affiliated with the Department of Cardiology at the Smidt Heart Institute and the Division of Artificial Intelligence in Medicine at the Cedars-Sinai Medical Center in Los Angeles. “We were pleasantly surprised that AI actually was superior. This really speaks to the high level of precision that automation delivers.”

In a recent interview, Dr. Ouyang also discussed another 

 that employed deep learning segmentation of cardiac magnetic resonance imaging (MRI) to examine how variations in left ventricle sphericity can impact cardiovascular risks. Based on their findings from a large cohort of nearly 39,000 participants from the UK Biobank, Dr. Ouyang and colleagues found that one standard deviation increase in the left ventricle sphericity index led to a 47 percent increased risk for cardiomyopathy and a 20 percent higher risk of atrial fibrillation.

In a recent video interview, David Ouyang, M.D., shared insights from two recent studies he co-authored on the use of artificial intelligence (AI) to improve initial assessment of left ventricular ejection fraction (LVEF) on echocardiography and ascertain cardiac risks associated with changes in the left ventricle sphericity index seen on magnetic resonance imaging (MRI).

Emerging AI Advances in Cardiac Imaging

For Raymond Y. Kwong, MD, MPH, FACC, FSCMR, long scan times with cardiac magnetic resonance imaging (MRI) can have a significant downstream effect on patient access to this technology. He noted the increased demand for cardiac MRI has led to wait times of three to five weeks for outpatients and four to five days for in-patients to be scheduled for a cardiac MRI.

“These numbers are really unacceptable for patient care from our standpoint,” noted Dr. Kwong, the director of Cardiac Magnetic Resonance Imaging in the Cardiovascular Division of the Department of Medicine at Brigham and Women’s Hospital in Boston, and a professor medicine at Harvard Medical School.

With this in mind, Dr. Kwong recently started using Vista.ai (formerly HeartVista) One-Click MRI, an artificial intelligence (AI)-enabled software that helps improve image quality as well as the efficiency of cardiac MRI procedures. At the recent Radiological Society of North America (RSNA) conference, Dr. Kwong shared his six-month experience with Vista.ai’s One-Click MRI and noted a 31 percent reduction in scan times based on 1,100 consecutive cardiac MRI studies performed between April 2022 and September 2022 for patients with cardiomyopathy or structural heart disease.

When employing full use of the Vista.ai One-Click MRI software, Dr. Kwong found that 90 percent of cardiac MRI studies could be completed in less than 45 minutes in comparison to 25 percent of non-AI-aided studies.

(Editor’s note: This interview was recorded prior to HeartVista’s announcement about the company name change to Vista.ai.)

In a recent video interview, Raymond Y. Kwong, MD, discussed his clinical experience with the Vista.ai (formerly HeartVista) One Click MRI software and recent research, presented at the Radiological Society of North America (RSNA) conference, that revealed a 31 percent decrease in cardiac MRI scan times for patients with cardiomyopathy or structural heart disease.

Morris Panner didn’t want to call the familiar PACS system outdated or antiquated. However, he did suggest that radiology is on the cusp of a revolution with medical image and data management that parallels the ongoing emergence of the radiologist from the reading room to being a key member of the interdisciplinary team in facilitating optimal patient outcomes.

“The PACS system is no longer a new invention. It is important and you can always improve it but what people are really looking for now is how to free that data, take that pixel information, share it, use it with other types of data and advance the liquidity and flexibility in data management. That was the revolution that came out of the SIIM (Society for Imaging Informatics in Medicine) meeting this year,” noted Panner, the president of Intelerad Medical Systems, in a recent video interview.

, and the more gradual “try it” phase for many radiologists as they discern the most optimal fit for AI in their current workflows. To that end, Panner also reviewed key aspects of Intelerad’s Enterprise Imaging and Informatics Suite. It is Panner’s hope that by emphasizing improved efficiency and quality in radiology workflows, the system can “free up brain space for great diagnostics.”

What's Next in Medical Image and Data Management in Radiology?

Not only do women have higher prevalence and mortality rates with ischemic heart disease (IHD) than men, they also have more atypical symptoms of the disease, according to researchers from the Beth Israel Deaconess Medical Center (BIDMC).

In a video interview, Diana Litmanovich, MD, chief of the cardiothoracic imaging section at BIDMC, and Rokas Liubauskas, a clinical research fellow in the radiology department of BIDMC, discussed their 

recent poster presentation at the American Roentgen Ray Society (ARRS) conference

, which focused on the impact of sex-based differences with risk factors, imaging, and the diagnostic workup of suspected IHD in women.

While diabetes mellitus and hypertension are well-established risk factors for myocardial infarction (MI), Dr. Liubauskas noted that they are higher risk factors in women than men. The authors also said that fewer women symptomatic for IHD present with typical symptoms such as chest pain. Common atypical symptoms in women who could have IHD may include nausea, vomiting and epigastric pain. Other complaints in women with possible IHD may include dyspnea, jaw pain, loss of appetite or lightheadedness.

When assessing women for potential coronary artery disease (CAD), Dr. Litmanovich explained that clinical predictive factors are reliable but less reliable in women compared to men. However, she maintained that predictability of an acute coronary event in women via imaging is better than that of men.

There are also key differences with imaging findings in this patient population. They pointed out that the smaller coronary artery diameter in women plays a key role with interpretation of imaging. Drs. Litmanovich and Liubauskas also discussed a lack of flow-limiting stenosis in over 50 percent of women symptomatic for IHD.

Other considerations impact the use of imaging devices for women with suspected IHD. While coronary computed tomography angiography (CCTA) has been recognized for its ability to help stratify risk in patients with CAD, the use of some medications to mitigate anxiety-related tachycardia in women may warrant heart rate monitoring, according to Dr. Liubauskas. When microvascular dysfunction is part of the equation for cardiac ischemia, Dr. Liubauskas says this requires functional tests for diagnosis.

When it comes to CAD, Dr. Litmanovich said women with preserved myocardium and ejection fraction may still have heart failure. In these cases, she said the use of magnetic resonance imaging (MRI) with delayed gadolinium enhancement may be warranted as “what looks normal on echocardiography or CT might actually correlate with abnormal MRI findings.”

Diagnosing Cardiac Ischemia in Women: Key Imaging Considerations

Despite the technological advances in transferring electronic health information, medical imaging data, to this day, is predominantly exchanged between instiutions via physical media (such as a CD or flash drive) that patients carry to an appointment at another facility.

Emphasizing the impact of this seemingly dated practice on workflow efficiencies within radiology and the broader field of health care, Arun Krishnaraj, MD, MPH and David Larson, MD, MBA, said the continued reliance on patients to transport medical images via physical media (such as a CD or flash drive) can lead to delays in patient care.

In their quest to change this dynamic, Drs. Krishnaraj and Larson recently co-authored a provocative article, “

Moving Toward Seamless Interinstitutional Electronic Image Transfer

ournal of the American College of Radiology (JACR)

. In the article and in a video interview with 

, Drs. Krishnaraj and Larson discussed the potential creation of a “linked multi-hub model” that would facilitate electronic transmission of medical images through image exchange companies that would connect different health-care facilities.

“Everyone in the imaging community should really see this as a call to arms to work with our imaging vendor exchange communities to solve this problem for the benefit of patients,” emphasized Dr. Krishnaraj, Chief of the Division of Body Imaging with the Department of Radiology and Medical Imaging at the University of Virginia School of Medicine.

'A Call to Arms' for Electronic Transfer of Medical Images Between Institutions

Welcome to Diagnostic Imaging’s Weekly Scan. I’m senior editor Whitney Palmer.

Before we get out our featured interview with Dr. Diana Miglioretti about a risk-based model designed to help providers prioritize which women to bring in for mammograms during a crisis, such as the COVID-19 pandemic, here are the top stories of the week.

Fetal cardiovascular MRI can be useful in providing information about congenital heart defects when echocardiography results are unclear, said a group of researchers in 

Although echocardiography is typically the tool of choice to catch these defects in utero, sometimes the acoustic window isn’t sufficient, leading to indeterminate images. In these cases, fetal CMR can provide useful details in 84 percent of cases, potentially impacting choices for mode of delivery, early postnatal care planning, and parental counseling. To determine how well fetal CMR performs, the team examined results from 31 fetuses with an average gestational age of 36 weeks between January 2017 and June 2020. Alongside that additional diagnostic information, the team determined the extra data bolstered parental counseling in 68 percent of cases.

Being a new radiologist can be difficult. You have to learn the ropes of your new practice, get to know your colleagues, and figure out how to handle the daily workload. It can be overwhelming – and, frankly, residency doesn’t necessary give you the skills you need navigate it all successfully. In an attempt to help you, a group of radiology experts from The Netherlands published a list of 10 survival tips this week in the 

Journal of the American College of Radiology

 They touched on finances, insurance, continuing medical education, setting boundaries, avoiding burnout, and more. Not only can these tips help the new radiologist, but they can also be good suggestions for how residency programs can improve how they prepare providers for the realities of clinical practice.

spoke with Dr. Diana Miglioretti, chief of biostatistics at the University of California-Davis School of Medicine, about the risk-based model she and her colleagues created. It is designed to help providers prioritize which women to bring in for screening mammography during times of crisis when resources and capacity are limited, such as during the COVID-19 pandemic. Here’s what she had to say about the impact of using such as model.

Diagnostic Imaging's Weekly Scan: April 2, 2021

 Weekly Scan. I’m senior editor Whitney Palmer.

Before we get to our featured interview with Dr. Lynn Baxter, director of breast imaging at Radiology Partners member practice Northside Radiology Associates about how to address COVID-19 vaccine-related adenopathies with patients, here are the top stories of the week.

Missing even one screening mammogram can put a woman at significantly higher risk for dying from breast cancer. According to a study of more than half a million women published in 

, researchers determined that undergoing consecutive mammograms reduces a woman’s risk by half – but, skipping out makes a big difference. From 1992 to 2016, investigators followed 549,091 women in Sweden to see how frequently they underwent screening. During the study, the country’s policy was to offer screening mammography to women ages 40 to 54 every 18 months – it was every 24 months for women ages 55 to 69. The researchers divided women into four groups – those who received two consecutive screenings; those who had their last, but not next-to-last; those who had their next-to-last, but not last; and those who had none. Overall, they identified 3,995 breast cancer deaths across the groups and determined that women who had both screenings had a 49-percent lower risk for breast cancer mortality. It was only 33 percent and 28 percent for women who had only their last or next-to-last screening, respectively. This benefit stretched out for 10 years, they said, with women who underwent both screenings experiencing a 50-percent drop in breast cancer mortality within a decade of the exams.

More radiologists are providing cardiac CT and MRI services, but these studies still are not as common as echocardiography and nuclear medicine, according to a recent study from 

. In a study from 2012 to 2017, investigators examined the number of cardiac CT and MRI exams performed, as well as the number of providers who conducted them. Based on their analysis, they found cardiovascular CT and MRI use rose by 97.4 percent and 75.5 percent, respectively. The number of providers also increased by 84.8 percent for MRI and 77.3 percent for CT. The majority of providers were men, and most were cardiologists or radiologists. However, while reimbursements rates for MRI and CT during the study period amounted to $16.2 million and $55.8 million, respectively, those number paled in comparison to reimbursement for echocardiography and nuclear medicine while came in at $5.9 billion and $4.2 billion, respectively.

This week, Andrew Colbert, senior managing partner and founding member of Ziegler’s Healthcare Investment Banking shared his thoughts on how radiology practices can help secure themselves financially during this turbulent healthcare environment. In his 

, he discussed five factors that are directly impacting the playing field currently: federal healthcare policy changes, industry consolidations and mergers, the push to outpatient service and consumerization, the economic impact of COVID-19, and Medicare payment reallocations. In addition to laying out how each of these factors is making an impact, Colbert pointed to an analysis that could help practices identify areas of investment and fortification, and he highlighted several key types of investments that could drive success.

 spoke with Dr. Lynn Baxter, director of breast imaging at Radiology Partners member practice Northside Radiology Associates about how to address COVID-19 vaccine-related adenopathies with patients. Not only did she discuss how both technologists and radiologists should approach this information with patients, but she shared how her practice, in particular, does it. Here’s what she said.

Diagnostic Imaging's Weekly Scan: March 1, 2021, to March 5, 2021

Welcome to Diagnostic Imaging’s Weekly Scan. I’m senior editor, Whitney Palmer.

Before we get to our featured interview this week with Dr. Donald Frush, instructor of radiology in the Duke University School of Medicine and Health System, about the announced recommendation against across-the-board gonad shielding with X-ray imaging from the National Council on Radiation Protection and Measurements (NCRP), here are the top stories of the week.

In contrast to what you might have anticipated, the severity of a patient’s case of COVID-19 is not necessarily linked to how well his or her lungs will recover from the virus. Fortunately, post-recovery imaging at least shows that most people’s lungs will not experience any long-term scarring. In a study from Trinity College in Dublin, published in the 

, investigators followed 153 patients for an average of 75 days in an outpatient clinic, evaluating their condition with chest X-rays and CT, as well as a six-minute walk test. They also examined blood samples for disease indicators, such as C-reactive protein. The results surprised them. Only 4 percent of patients who had previous abnormal X-rays had any evidence of lung scarring on chest CT, and shorter six-minute walk test distances were associated with frailty and longer hospitalizations – not disease severity. These outcomes point to a need for greater cardiovascular and fitness assessment, as well as rehabilitation for patients who have fatigue and breathlessness after COVID-19 recovery.

Looking to reduce your emergency department medical imaging recall rates? It might be as easy as adding an attending radiologist to the overnight hours, according to University of Toronto researchers. This group of investigators tested an intervention at Sunnybrook Health Sciences Center from 2016 to 2018, and they found having an attending radiologist in-house after-hours sliced imaging exam recalls by approximately 90 percent. In fact, they said in their article in 

, the average number of recalls plummeted from 61 annually to 7. This drop was impressive they said since the number of images ordered in the emergency department actually rose annually during this time, climbing from 13,883 in 2016 to 15,112 in 2018. While radiology residents still provided preliminary reports and remained the main points-of-contact for referring physicians, the attending radiologists were responsible for final reports for both emergency department patients and inpatients. Not only did their intervention improve work flow, but it also improved patient comfort and safety because patient were not called back for a re-scan. In addition, emergency physicians also reported a higher level of satisfaction.

New findings this week from Vanderbilt University contradicted some alarming results published in the fall about the effects of COVID-19 on the cardiovascular health of athletes. Initially, it was reported that approximately 15 percent of athletes suffered from myocarditis, captured on cardiac MRI, after recovering from the virus. Vanderbilt’s investigators determined the real amount is 3 percent, and their findings were published by the American Heart Association in 

Vanderbilt researchers compared COVID-19-positive athletes to 60 healthy controls to make this determination. Unfortunately, they realized, no screening tests that they evaluated were effective in pinpointing which athletes had myocarditis – this was a let-down because the team had hoped those screenings would have been definitive, limiting the need for cardiac MRI to the most necessary instances. Still, in one beneficial result, they found both COVID-19-positive and health athletes experience similar levels of benign scarring in healthy heart muscle in the same location, indicating it is not a consequence of the virus and should not restrict an athlete from competition.

And, finally this week, Diagnostic Imaging spoke with Dr. Donald Frush, an instructor of radiology at Duke University School of Medicine and Duke University Health System about the recommendations against the universal use of gonad shielding during X-ray imaging that were released this week. Frush, who served as the chair of the NCRP subcommittee on gonadal shielding discussed the reasoning behind the recommendation, the challenges that exist to implementing the protocol change, what facilities can do to successfully shift their shielding practice, and the drawbacks that exist to still using shielding routinely.
