Emergency departments (EDs) could see significant cost savings by eliminating oral contrast administration for most patients presenting with nontraumatic abdominal pain, according to a new study published in the Journal of the American College of Radiology.

“We found no evidence of intracranial gadolinium deposition on brain MR images in patients who had intraarticular gadolinium administered for MR arthrography and no other GBCA exposure,” wrote lead author Lauren Ladd, MD, and a radiologist at the Indiana University School of Medicine.

Researchers at Cedar-Sinai have developed a new equation that can better determine whole-body fat percentage among adults.

The Radiological Society of North America (RSNA) kicked off its second annual machine learning challenge on Aug. 27, inviting teams to create an algorithm capable of identifying and localizing pneumonia on chest x-rays.

Among 477,516 people in the Kaiser Permanente Southern California health system who were treated for high blood pressure, those who reached systolic blood pressure below 110 mm Hg at any point during a one-year period were twice as likely to faint or fall as patients who remained above that threshold.

Researchers found coronary computed tomography angiogram (CTA) in addition to standard cardiac testing may reduce patients at risk for coronary heart disease or a heart attack.

Researchers at the U.S. Department of Energy’s Brookhaven National Laboratory in Upton, New York, have developed a novel x-ray imaging technique for visualizing materials too thick to be imaged by existing methods. The team wrote about its findings in a recent paper published in Optica.

Though it’s used routinely to discourage repeat cardiovascular disease (CVD) events, a daily dose of aspirin is unlikely to prevent a first-time heart attack, according to research presented this week in Munich.

A new study suggests coronary CT angiography (CTA), in addition to standard care in patients with stable chest pain, lowers death rates from coronary heart disease (CHD) or nonfatal myocardial (MI) infarction at five years, compared to standard care alone.

The Radiological Society of North America (RSNA) announced the launch of its second annual machine learning challenge on Monday, Aug. 27. Teams will be invited to develop algorithms to identify and localize pneumonia in chest x-rays.
