Freezing the posterior vagal trunk, the nerve that sends hunger-related signals to the brain, could help patients with mild-to-moderate obesity lose weight, according to research presented at the Society of Interventional Radiology (SIR) annual meeting in Los Angeles.

Renal computed tomography angiography (CTA) is an effective resource for radiologists with numerous benefits, but it requires the application of contrast medium that could potentially cause issues in patients with renal impairment.

Mental illness can be difficult to quantify, with the complexity of the brain obscuring symptoms and improvements. But single photon emission computed tomography (SPECT) imaging may identify those likely to respond to treatment for depression by examining blood flow and activity patterns.

A team from Stanford University used virtual reality (VR) technology to turn CT scans into 3D images to help radiologists prepare to repair splenic artery aneurysms.

Interruptions don’t impact an on-call radiologist’s accuracy, according to a new study in the Journal of Medical Imaging, but they can increase time spent on each case.

The Society of Interventional Radiology (SIR) debuted the first virtual reality 360 (VR360) training video featuring interventional radiology being performed in practice during the SIR 2018 annual meeting in Los Angeles.

Radiologists can provide significant value by communicating the benefits and risks associated with radiation to the parents or guardians of pediatric patients, and a group of researchers provided numerous strategies for such communication in a new analysis for the Journal of the American College of Radiology.

The use of gadolinium-based contrast agents (GBCAs) in MRI brain studies was long thought to be safe for patients without severe renal insufficiency, but in 2014, researchers started finding evidence that GBCAs can leave traces of gadolinium (GD) behind in the brain.
