While the benefits of resistance training on musculoskeletal health are on daily display in any weightlifting room, the question of how much good all those sets and reps do for the heart has been open. Now comes an imaging-based answer from Germany, where researchers using MRI found measurable cardiac changes in a randomized group of novice male “gym rats” after they’d worked out regularly for around half a year.

Acute chest-pain patients imaged with coronary CT angiography (CCTA) are more likely to receive revascularization and invasive coronary interventions that don’t clearly improve outcomes than patients evaluated with standard functional tests such as stress EKG and stress echocardiography, according to a meta-analysis of randomized clinical trials.

Imaging techniques can be beneficial in identifying ischemic heart disease during minimally invasive autopsies, according to a study presented at RSNA 2017 in Chicago.

Former National Football League (NFL) players have significantly larger aortas than similarly aged men in the general population, potentially putting them at higher risk for aortic rupture or dissection, according to research presented Nov. 29 at RSNA 2017 and published online in Circulation: Cardiovascular Imaging.

Multidetector computed tomography (CT) could play a pivotal role in improving the outcomes of transcatheter aortic valve replacement (TAVR) procedures, research presented at the 103rd annual RSNA symposium suggests.
