Coronavirus (COVID-19) | December 06, 2021

Kate Hanneman, M.D., MPH FRCPC, director of cardiac imaging research JDMI, and the medical imaging site director at Toronto General Hospital, Women’s College Hospital, was an author on a recent overview of cardiac MRI assessments of non-ischemic myocardial inflammation caused by the COVID-19 vaccine. She presented this study and other related data at the 2021 Radiological Society of North America (RSNA) meeting. 

The rare side effect from the COVID vaccine is seen mainly in young men between ages 12-29. It appears to resolve on its own after a couple days, but longer term monitoring is needed to show if there is any lasting cardiac damage. A small number of single cases with follow up MRI imaging so far have not shown long term damage. 

Hanneman noted the incidence of vaccine-related myocarditis is very rare and people have a much high probability of getting much more serious COVID-viral myocarditis is they are not vaccinated. She said so the risk-vs-benefit analysis currently shows it is better to get vaccinated to prevent or lessen the effects of COVID.

Jeffrey T. Chapman, a medical student at the University of Texas Southwestern Medical Center, Explains how watching movies can be used to help sedate pediatric radiation therapy patients. He presented the results of the Pediatric Radiation Oncology With Movie Induced Sedation Effect (PROMISE) study at the 2021 American Society of Radiation Oncology (ASTRO) annual meeting.

Children usually have to be sedated with anesthesia to keep them immobile each day for weeks for their daily fractions of radiotherapy. This presents problems because the child will have side effects from the anesthesia and face issues with eating only at certain times. UTSW developed a system where the child can watch a movie and if they move the movie and the radiation beam both immediately shut off. This trains the child to stay still during treatments without the need for anesthesia.

Artificial Intelligence | July 22, 2021

This is an overview of trends and technologies in radiology artificial intelligence (AI) applications in 2021. Views were shared by 11 radiologists using AI and industry leaders, which include:

Randy Hicks, M.D., MBA, radiologist and CEO of Reginal Medical Imaging (RMI), and an iCAD Profound AI user.

• Prof. Dr. Thomas Frauenfelder, University of Zurich, Institute for Diagnostic and Interventional Radiology, and Riverain AI user.

Jill Hamman, world-wide marketing manager at Carestream Health.

Sebastian Nickel, Siemens Healthineers, global product manager for the AI Pathway Companion. 

There has been a change in attitudes about AI on the expo floor at the Radiological Society of North America (RSNA) over the last two years. AI conversations were originally 101 level and discussed how AI technology could be trained to sort photos of dogs and cats. However, in 2020, with numerous FDA approvals for various AI applications, the conversations at RSNA, and industry wide, have shifted to that of accepting the validity of AI. Radiologists now want to discuss how a specific AI algorithm is going to help them save time, make more accurate diagnoses and make them more efficient.

With a higher level of maturity in AI and the technology seeing wider adoption, radiologists using it say AI gives them additional confidence in their diagnoses, and can even help readers who may not be deep experts in the exam type they are being asked to read. 

With a myriad of new AI apps gaining regulatory approval from scores of imaging vendors, the biggest challenge for getting this technology into hospitals is an easy to integrate format. This has led to several vendors creating AI app stores. These allow AI apps to integrate easily into radiology workflows because the apps are already integrated as third-party software into a larger radiology vendors' IT platform.  

There are now hundreds of AI applications that do a wide variety of analysis, from data analytics, image reconstruction, disease and anatomy identification, automating measurements and advanced visualization. The AI applications can be divided into 2 basic types — AI to improve workflow, and AI for clinical decision support, such as diagnostic aids.

On the workflow side, several vendors are leveraging AI to pull together all of a patients' information, prior exams and reports in one location and to digest the information so it is easier for the radiologist to consume. Often the AI pulls only data and priors that relate to a specific question being asked, based on the imaging protocol used for the exam. One example of this is the Siemens Healthineers AI Clinical Pathway and Siemens AI integrations with PACS to automate measurements and advanced visualization.

AI is also helping simplify complex tasks and help reduce the reading time on involved exams. One example of this is in 3-D breast tomosythesis with hundreds of images, which is rapidly replacing 2-D mammography, which only produces 4 images. Another example is automated image reconstruction algorithms to significantly reduce manual work. AI also is now being integrated directly into several vendors' imaging systems to speed workflow and improve image quality.

Vendors say AI is here to stay. They explain the future of AI will be automation to help improve image quality, simplify manual processes, improved diagnostic quality, new ways to analyze data, and workflow aids that operate in the background as part of a growing number of software solutions. 

Several vendors at RSNA 2020 noted that AI's biggest impact in the coming years will be its ability to augment and speed the workflow for the small number of radiologists compared to the quickly growing elder patient populations worldwide. There also are applications in rural and developing countries were there are very low numbers of physicians or specialists.

The Elekta Harmony radiotherapy system gained FDA clearance in the summer of 2021 and was on display for the first time at the American Society of Radiation Oncology (ASTRO) 2021 meeting. It offers fast treatments and the ability to track and treat multiple metastases at the same time. 

It has a large round screen on the machine so the patient's information is immediately available table side. It uses facial recognition to verify the correct patient is in the room for treatment.

The speed of the treatment delivery increased over that of prior systems, so the time a patient spends in the treatment room for lung SBRT went from 30 minutes down to less than 2 minutes. SBRT prostate went down from 5 minutes to 90 seconds. It also can perform hypofractionation lung therapy in a single 20 minute treatment.

Siemens and Philips demonstrated examples of new imaging software to convert MRI datasets into synthetic computed tomography (CT) datasets at the American Society of Radiation Oncology (ASTRO) 2021 meeting. The synthetic CT datasets can be used for radiotherapy treatment planning. This eliminates the need for a separate CT scan, reducing time and cost in patient care. 

The technology uses an algorithm to convert the MRI dataset into a CT grayscale Hounsfield units. The Hounsfield units correlate with the densities of the various tissues and are used to calculate the doses required and beam routes needed in radiotherapy to treat a patient.

Walter Curran, Jr. M.D., FACR, FASCO, GenesisCare global chief medical officer, discusses three technologies that are helping advance radiation oncology care during the American Society of Radiation Oncology (ASTRO) 2021 meeting. These technology advances include:

   • Prostate-specific membrane antigen (PSMA) positron emission tomography (PET) imaging for prostate cancer.

   • MRI-linear accelerator (Linac) systems that allow real-time imaging during radiation therapy.

   • Remote treatment planning to help radiation treatment centers that are in rural areas.

Prostate cancer is one of the most common cancers in men. The new PSMA PET imaging is expected to significantly improve how prostate cancer is detected and treated. The FDA approved the drug for PET nuclear imaging of PSMA-positive lesions in men with prostate cancer. 68Ga-PSMA-11 is a radioactive imaging agent that binds to prostate cancer cells to help localize prostate cancer cells.

Yael Eshet, M.D., MSc, a diagnostic radiology specialist at Sheba Medical Center in Israel, was the lead author on a recent study that showed COVID-19 (SARS-CoV-2) vaccine adenopathy can persist more than 6 weeks. This swelling of lymph nodes is similar to what is seen cancer and infections and the new findings show it can last longer than 7-10 weeks. The current recommended time people should delay medical imaging is 6 weeks after receiving a COVID vaccine to avoid a misdiagnosis,[2] but this new study shows there is increased inflammation shown on PET-CT imaging for much longer.

These were the findings in the Radiology published study "Prevalence of Increased FDG PET/CT Axillary Lymph Node Uptake Beyond 6 Weeks after mRNA COVID-19 Vaccination."[1]

Researchers using fluorodeoxyglucose (FDG)-positron emission tomography (PET) have found increased FDG uptake in the lymph nodes of patients 7-10 weeks past their second mRNA-based Pfizer-BioNTech COVID-19 vaccination. This new information indicates a persistent immune response that could be mistaken on imaging exams for serious conditions like lymphoma over a much longer period of time.

Recent recommendations for post-vaccine lymphadenopathy advise scheduling routine imaging, such as screening mammography, before, or at least 6 weeks after, the final vaccination dose to eliminate false positive results. However, this new research showed that avid axillary lymph node uptake was present beyond 6 weeks after the second vaccination in more than 29% of the patients in the study cohort.

The authors stated “This study shows that avid axillary lymph node uptake on FDG PET/CT can be detected in more than a quarter of our patient population even beyond 6 weeks after the second dose of the mRNA-based COVID-19 vaccination. Compared to a previous study showing normalization of FDG uptake within 40 days of receiving an inactivated H1N1 influenza vaccine, we found uptake persistence even at 70 days. Physicians should be aware of this potential pitfall.”

Some images in this video are from another Radiology study, which showed PET tracer uptake at the COVID vaccine injection site and other examples of axillary adenopathy.[3]

The 11 minute video condenses down the highlights of workflow efficiencies seen during two days o vendor booth tours.

There was a clear trend of many vendors moving to new platforms that leverage more modern cloud-platform interfaces. This enables faster study loading speeds over web connections. These platforms are also using deeper integration of third-party applications and artificial intelligence (AI) software that do not require separate logins or workflows. Read more about these key trends observed at HIMSS 2021.

Vendors also showed various ways they have speed up radiology workflows. These included easier to customize hanging protocols, automated fetching of prior exams, synchronizing views and scrolling between a current a prior exams, use of timeline views of patient priors and procedures to make it easier to find relevant images and reports, and integration of all types of images into one unified viewer. 

Specific examples in this video include: 
   • Visage Imaging: Example of high speed cloud PACS access to 3D mammograms and and priors. This first video clip shows a demonstration of opening large datasets in a matter of a couple seconds over a network connection from a tethered cellphone.
   • Visage Imaging: Ability to access multiple modalities on one PACS viewer
   • GE Healthcare: Examples of fast access to priors and location on screen 
   • GE Healthcare: Example of deep integration of third-party AI software
   • Siemens: Overview of its Lung AI Pathway Companion workflow  
   • Change Healthcare: Enabling fast ability to free rotate around lung anatomy rather than going slice by slice manually 
   • Change Healthcare: Color-coded bar shows loading progress of an image or data set
   • Infinitt: Hanging protocol automation to find same view on prior and link for synchronized scrolling   
   • Infinitt: Use of timeline to get quick view of prior reports and images without needing to open whole exam 
   • Siemens: Example of deeper integration with third-party apps, in this case Epsilon strain echo analysis  
   • Fujifilm: Integrated advanced visualization in the radiology workflow for liver segmentation used for surgical or embolization planning 
   • Fujifilm: Example of life-like cinematic rendering of a CT scan offers new ways to view anatomy and explain it to a patient 
   • Visage Imaging: Example of enterprise platform able to bring in full original format advanced visualization reconstructed images on a single platform viewer

Coronavirus (COVID-19) | August 31, 2021

Several radiology IT vendors at 2021 Healthcare Information Management Systems Society (HIMSS) conference demonstrated computed tomography (CT) imaging advanced visualization software software to help automatically identify and quantify COVID-19 pneumonia in the lungs. These tools can help speed assessment of the lung involvement and serial tracking can be used to assess the patient's progress in the hospital and during long-COVID observation. 

Examples of COVID analysis tool shown in this video include clips from booth tours at: 
   • Fujifilm
   • Siemens Healthineers 
   • Canon (Vital)

Canon received FDA clearance for its tool under and emergency use authorization (EUA).

Siemens said its tool was part of its lung analysis originally developed for cancer but modified and prioritized to aid in COVID assessments.

Information Technology | August 30, 2021

David Danhauer, M.D., FAAP, FHIMSS, chief medical information officer, Owensboro Health, Owensboro, Ky., explains the implementation of healthcare information technology (IT) to coordinate followup on incidental radiology findings. He presented on this topic in a session at the Healthcare Information Management Systems Society (HIMSS) 2021 meeting. 

Their system starts with key words being identified to flag incidental findings by the voice recognition system used to enter radiology report information. IT interfaces with the electronic medical record create a list of patients that need followup and what departments the incidental findings relate to so a coordinator can connect the patient with the proper subspecialty.

Danhauer said many of the incidental findings at his center include lung nodules and abdominal aortic aneurisms. In the past, many of these were lost to followup, but the new system now promotes follow through to get the patient the care they need. This has helped increase revenue, improve patient care and lowers the health system's liability profile. 

The system experienced several patient safety events due to gaps in care coordination with incidental findings documented in the radiology report, but missed by referring physicians. A patient safety initiative he helped implement automating the workflow resulted in a nine-fold increase in identifying and communicating incidental findings for improved patient safety.

Coronavirus (COVID-19) | May 11, 2021

Yael Eshet, M.D., MSc, a diagnostic radiology specialist at Sheba Medical Center in Israel, was the lead author on a recent study that showed COVID-19 (SARS-CoV-2) vaccine adenopathy can persist more than 6 weeks. This swelling of lymph nodes is similar to what is seen cancer and infections and the new findings show it can last longer than 7-10 weeks. The current recommended time people should delay medical imaging is 6 weeks after receiving a COVID vaccine to avoid a misdiagnosis,[2] but this new study shows there is increased inflammation shown on PET-CT imaging for much longer.

These were the findings in the Radiology published study "Prevalence of Increased FDG PET/CT Axillary Lymph Node Uptake Beyond 6 Weeks after mRNA COVID-19 Vaccination."[1]

Researchers using fluorodeoxyglucose (FDG)-positron emission tomography (PET) have found increased FDG uptake in the lymph nodes of patients 7-10 weeks past their second mRNA-based Pfizer-BioNTech COVID-19 vaccination. This new information indicates a persistent immune response that could be mistaken on imaging exams for serious conditions like lymphoma over a much longer period of time.

Recent recommendations for post-vaccine lymphadenopathy advise scheduling routine imaging, such as screening mammography, before, or at least 6 weeks after, the final vaccination dose to eliminate false positive results. However, this new research showed that avid axillary lymph node uptake was present beyond 6 weeks after the second vaccination in more than 29% of the patients in the study cohort.

The authors stated “This study shows that avid axillary lymph node uptake on FDG PET/CT can be detected in more than a quarter of our patient population even beyond 6 weeks after the second dose of the mRNA-based COVID-19 vaccination. Compared to a previous study showing normalization of FDG uptake within 40 days of receiving an inactivated H1N1 influenza vaccine, we found uptake persistence even at 70 days. Physicians should be aware of this potential pitfall.”

Some images in this video are from another Radiology study, which showed PET tracer uptake at the COVID vaccine injection site and other examples of axillary adenopathy.[3]

Breast Imaging | March 26, 2021

Constance "Connie" Lehman, M.D., Ph.D., chief of breast imaging, co-director of the Avon Comprehensive Breast Evaluation Center at the Massachusetts General Hospital, and professor of radiology at Harvard Medical School, explains issues and suggested guidelines for women who receive the COVID-19 vaccine and need to get a mammogram. In the first three months since the vaccines have been released, there have been numerous case reports of the vaccine causing swollen lymph nodes. This is would usually raise a red flag for breast cancer, but is normal for many women receiving the vaccine as their body's immune system gears up against the virus. 

Lehman said cases reports of axillary adenopathy have been identified on breast imaging after coronavirus disease (COVID-19) vaccination and are rising. Lehman et al. proposed a pragmatic management approach in a recent article in the American Journal of Roentgenology (AJR).[1]

In the settings of screening mammography, screening MRI and diagnostic imaging work-up of breast symptoms, with no imaging findings beyond unilateral axillary adenopathy ipsilateral to recent (prior six weeks) vaccination, they report the adenopathy as benign with no further imaging indicated if no nodes are palpable six weeks after the last vaccine dose. 

For patients with palpable axillary adenopathy in the setting of ipsilateral recent vaccination, clinical follow-up of the axilla is recommended. In all these scenarios, axillary ultrasound is recommended if clinical concern persists six weeks after vaccination. 

In patients with recent breast cancer diagnosis in the pre- or peri-treatment setting, prompt recommended imaging is encouraged as well as vaccination (in the thigh or contralateral arm). The recommendations align with the ACR BI-RADS Atlas and aim to: 1) reduce patient anxiety, provider burden, and costs of unnecessary evaluation of enlarged nodes in the setting of recent vaccination, and 2) avoid further delays in vaccinations and breast cancer screening during the pandemic.

Artificial Intelligence | November 11, 2020

Artificial Intelligence (AI) is becoming more common place in radiology practices, and emerging technologies are providing radiologists with sophisticated detection software to aid their reading and provide support for a busy workflow. With the progression of AI technology, vendors must look not only at what AI can do for the radiologist, but how the radiologist and the technician interact with that technology –  the goal should be increasing accuracy while also positively improving workflow. GE Healthcare is working to improve radiology AI workflow in its Centricity Universal Viewer.

Three key opinion leaders offers their views on what is needed to make AI more valauble and accessible to radiologists. These include:

   • Amy Patel, M.D., breast radiologist, medical director, Liberty Hospital Women's Imaging, assistant professor of radiology, University of Missouri-Kansas City.

   • Prof. Dr. Thomas Frauenfelder, M.D., vice chairman and professor of thoracic radiology, Institute for Diagnostic and Interventional Radiology, University of Zurich.

   • Randy Hicks, M.D., chief executive officer, Regional Medical Imaging.

MRI Breast | October 14, 2020

Professor Christiane Kuhl, M.D., director of radiology, University Hospital Aachen, Germany, explains how breast magnetic resonance imaging (MRI) can be used to clearly identify breast cancers in women with dense breast tissue. In women with dense breasts, it can be very difficult to detect many cancers on standard mammograms because the cancers and dense tissue both appear white. MRI can help clearly define tumors and identify which nodules are cancer and which are benign, which can help greatly reduce the need for biopsies.

Kuhl is an expert in breast imaging and breast MRI. She helped develop an a shortened MRI protocol that allows breast MR images to be created in 3 minutes or less, rather than standard protocols that can take up to 30 minutes. In the interview she shows patient case examples of standard mammograms and the MRI supplemental imaging for the same patient to show the hidden tumors. 

She also explains the differences between standard 2-d mammography, the current standard of care, and the newer 3-D mammogram tomosythnesis technology, breast ultrasound and breast MRI technologies.
