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.

Coronary CT angiography leads to questionably appropriate interventions

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.

Ultrasound needle enables clear imaging during heart procedures

The first optical ultrasound needle enables real-time imaging of heart tissue during minimally invasive procedures, according to researchers in the United Kingdom.

RSNA 2017: MRI, biopsy offer minimally invasive alternative to conventional autopsy

RSNA 2017: CT shows 30% of ex-NFL players have enlarged aortas

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.

RSNA 2017: CT imaging crucial to accurate annular valve measurements

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.

CT scans for chest pain widely performed, rarely valuable

Patients presenting in the emergency department with pronounced chest pain but no other signs of acute coronary syndromes don’t have better outcomes when they’re sent for stress testing or coronary CT angiography (CCTA) on top of gurney-side clinical assessment with blood testing, echocardiogram and so on.

Novel catheter combines FLIm, IVUS to assess plaque buildup in heart patients

A newly developed, single-catheter probe that combines intravascular ultrasounds with fluorescence lifetime imaging (FLIm) in one device could be the answer to physicians’ difficulties predicting plaque rupture, a study published in Scientific Reports suggests.

Left ventricular puncture proposed for whole-body PMCTA

A team of researchers has introduced a whole-body, post-mortem CT angiography (PMCTA) approach that could save time and money without requiring specialized equipment. By puncturing the left ventricle percutaneously and adding a contrast agent, researchers were able to identify threats for thromboembolism and aneurysm in a small sampling of cadavers.

PET outperforms SPECT, CCTA in diagnosing coronary artery disease

Researchers have directly compared the performance of three noninvasive imaging methods for diagnosing myocardial ischemia—and they identified positron emission tomography (PET) as the most accurate.
