'Delusions' and mental illness led radiologist to drive family off cliff, defense claims

The California physician may not face prison time after all, if a judge grants his defense team’s request that he be admitted to a mental health diversion program.

New PET technique spots 'smoldering' changes not visible on MRI in the brains of MS patients

The new technique uncovers hidden inflammation in patients who, despite undergoing extensive treatment for the condition, had worsening symptoms.

Natural language processing spots reporting gaps, racial bias

Finding such discrepancies is critical to the continuity of patient care, as medical records and reports are often utilized across multiple providers and facilities.

Rad techs helpfully ‘stand in a surgeon’s shoes’ thanks to virtual reality

Johns Hopkins researchers demonstrated the worthiness of the concept this year.

ChatGPT shows 'significant promise' in guiding contrast-related decisions

This could be especially helpful when timely clinical decisions relative to the use of a contrast agent need to be made.

Actionable tips imaging departments can implement to reduce energy consumption

With the earth’s warmest March on record in 175 years barely in the rearview mirror, a team of radiology experts says medical imaging must step up its sustainability efforts.

Advanced artificial intelligence (AI) models can evaluate cardiovascular risk in routine chest CT scans without contrast, according to new research published in Nature Communications.[1] In fact, the authors noted, the AI approach may be more effective at identifying issues than relying on guidance from radiologists. Representative non-contrast CT slices for two patients (left), with super-imposed segmentations (right). One artificial intelligence (AI) model was used to segment a cardiac mask.

AI predicts cardiovascular risk during CT scans—no invasive tests or contrast required

Two advanced algorithms—one for CAC scores and another for segmenting cardiac chamber volumes—outperformed radiologists when assessing low-dose chest CT scans.

Surveillance breast MRI findings linked with future second cancer

The new research focused specifically on associations between background parenchymal enhancement—a known risk factor for breast cancer, visualized on surveillance MRI exams—and secondary breast cancers.

Ultrasound measurements can predict osteoporosis, study shows

Experts compared the cortical thickness of three bones—the radius, tibia and second metatarsal—of 200 volunteers who had undergone prior bone mineral density measurements to evaluate the ultrasound method’s accuracy.

VIDEO: AI for stroke detection on CT imaging

Bibb Allen, MD, FACR, chief medical officer of the American College of Radiology (ACR) Data Science Institute, explains the trend of using AI for the automated detection of stroke on computed tomography (CT) imaging and the need to include radiologists on the stroke care team.

How effective are guidelines for managing incidental pulmonary nodules spotted on CT?

The authors of the study hypothesized that they would find malalignments due to the nature of how the 2017 Fleischner Society guidelines, in that they do not pertain to incidentally detected nodules.
