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.

Temple’s Susan Wiegers, MD, elected president of ASE

Susan E. Wiegers, MD, of Temple University School of Medicine in Philadelphia, has taken over the one-year term of president of the American Society of Echocardiography (ASE) following ASE’s annual meeting in Boston.

SNMMI: Scanning for cardiac amyloid could help predict heart attacks

While amyloid imaging is typically discussed with regard to diagnosing Alzheimer’s disease, a team of French researchers, presenting at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2015 annual meeting, have found that amyloid scans of the heart can predict major cardiac events.

CCTA links noncalcified arterial plaque to diabetes, blood pressure and cholesterol

CT angiography (CCTA) is effective at measuring levels of unstable arterial plaque in asymptomatic patients, which is associated with the development of diabetes, high blood pressure and elevated “bad” cholesterol, according to results of a study published online June 2 in the journal Radiology.

Hospitals combine “lean” model and MRI to speed acute stroke treatment

Timing is everything when it comes to emergency stroke response—patients who are treated within 60 minutes of the initial event have significantly improved outcomes. That fact led two Washington DC area hospitals to borrow ideas about “lean” production processes from profit-driven manufacturers to reduce the time interval between arrival and treatment for acute stroke victims, according to a recent study by the National Institute of Health (NIH) published online May 13 in the journal Neurology.

The multi-pronged approach to reducing MPI dose

The use of myocardial perfusion imaging (MPI) has spiked over the past four decades and along with it individual patient dose. A comprehensive effort to reduce that dose could reduce unnecessary procedures and reduce the risk of downstream cancers, according to a meta-analysis published in the April issue of the Journal of Nuclear Medicine.

Routine CTCA for chest pain could cut heart attack rates

CT coronary angiography (CTCA) can clarify the diagnosis of angina due to coronary heart disease, leading to a reduced need for further stress testing and enabling more targeted interventions. Ultimately, changes in treatments stemming from the addition of CTCA to standard clinical care could reduce fatal and non-fatal heart attack rates, according to the SCOT-HEART study.

From the heart: Imaging at ACC.15

Tomorrow in San Diego, thousands will gather to kick off the start of the American College of Cardiology’s Annual Scientific Session & Expo, which runs from March 14 – 16. Cutting-edge imaging in the cardiology space will be on display throughout the conference, from the late-breaking trials to the educational sessions.

Imaging at ACC.15: Session Spotlight

The focus of the cardiology world will be on San Diego for the American College of Cardiology’s Annual Scientific Session & Expo on March 14–16. As usual, imaging will be featured prominently, so read on to learn about the can’t-miss imaging sessions at ACC.15.

Cardiac CT as effective as TEE in predicting recurrent stroke

Transesophageal echocardiography (TEE) is the imaging modality of choice for doctors treating patients with ischemic stroke, but cardiac CT is just as effective at predicting recurrent strokes, according to a study published in the March issue of Radiology.

3D-printed bioplastics could be the future of interventional radiology

Devices and treatments specifically designed to match individual patient anatomy using 3D printing technologies and resorbable bioplastics are effective at providing targeted treatments against infection and cancer, according to a study presented at the Society of Interventional Radiology’s Annual Scientific Meeting.
