Clinical

This channel newsfeed includes clinical content on treating patients or the clinical implications in a variety of cardiac subspecialties and disease states. The channel includes news on cardiac surgery, interventional cardiologyheart failure, electrophysiologyhypertension, structural heart disease, use of pharmaceuticals, and COVID-19.

MRA for pulmonary embolus

MR angiography a suitable alternative to CT when ruling out pulmonary embolus

The modality switch became especially important during the iodinated contrast shortage of 2022 when clinics were forced to deploy mitigation tactics as a means of preserving their contrast supply. 

A figure from the study shows a chest radiograph with an area of consolidation involving right lower lung consistent with pneumonia, as well as right pleural effusion. The deep-learning model predicted risk of 30-day mortality of 9%. Right: Gradient- weighted class activation map shows that model prediction was influenced by separate area of image corresponding with heart and liver (yellow and light blue colors). Patient’s CURB-65 score was 4. Patient recovered from pneumonia and remained alive. AJR Image

Deep learning predicts pneumonia mortality on chest X-rays

AI was able to predict 30-day mortality risk predictions more accurately that the current risk assessment.

Cardiac ultrasound could lead to key advances in heart attack care, drug delivery

Jonathan Lindner, MD, offers an update on the use of echocardiography and bubble contrast agents in a therapy role to help revascularize STEMI patients and increase drug and gene delivery.

COVID causes increase risk of clotting. Example of a pulmonary embolism. CT pulmonary angiograms in a 77-year-old man with COVID-19 and a saddle embolus to pulmonary arteries (black arrow in A) extending into right and left pulmonary arteries (white arrows) in (A, B) axial and (C) coronal planes. Arrowheads show pulmonary changes associated with COVID-19 and possible lung infarction (black arrow in C). (D) Axial image at the level of the ventricles shows right-sided heart strain. RSNA. COVID PE

'Concerning' CT findings may lead to unnecessary hospitalization in PE patients

CT findings that have historically been deemed as concerning relative to PE might not hold as much weight when it comes to associated risks as previously thought, new analysis suggests.

New MRI technique offers detailed view of COVID's impact on the brain

The new technique mixes MRI signals at different gradient pulse strengths and timings, offering better visualization of differences in the way water molecules move through tissues.

AI primed for pulmonary nodule detection in adults, falls short in pediatric population

Artificial intelligence tools have proven to be beneficial in detecting pulmonary nodules on chest CTs of adults, but less is known about their utility in pediatric populations. 

University of Minnesota team develops compact portable MRI

Curbside MRI: Experts are developing system small enough to fit in a pickup

Someday, getting an MRI exam could be as simple as having food delivered to your door—at least that is the hope of a group of experts at the University of Minnesota who are working on a compact system said to be small enough to sit in the bed of a truck.

Around the web

CCTA is being utilized more and more for the diagnosis and management of suspected coronary artery disease. An international group of specialists shared their perspective on this ongoing trend.

The new technology shows early potential to make a significant impact on imaging workflows and patient care. 

Richard Heller III, MD, RSNA board member and senior VP of policy at Radiology Partners, offers an overview of policies in Congress that are directly impacting imaging.
