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.

MRI of pacemaker patients requires close radiology+cardiology collaboration

Thanks to advances in MRI-compatible cardiac device technology, pacemakers and implantable cardioverter defibrillators (ICDs) are no longer absolute contraindications for MRI exams. The devices remain relative contraindications for MRI, however, and their presence in MRI patients calls for radiologists and cardiologists to work closely together in order to both ensure patient safety and minimize legal risk.  

Research explores laser-based imaging platform for atherosclerosis

A new laser-based camera could one day become the tool that will help physicians know who is at risk of atheroscerlosis, by providing better views of potential problem areas.

MRI provides new insight into different forms of heart failure

MRI was used to measure oxygen consumption in the legs of heart failure patients by researchers at the University of Texas, who from this noninvasive technique gained extra insight into different forms of heart failure.

PET/CT shows how stress in the brain today manifests as cardiovascular problems tomorrow

The connection between chronic emotional stress and subsequent cardiovascular disease has long been substantiated on mostly circumstantial evidence. Now it’s been empirically established with imaging: A new study has put pictures to the heretofore unseen brain mechanism behind the mind/body double trouble.  

Machine learning proves a plus in cardiopulmonary care

Researchers have shown that machine learning of 3D patterns in cardiac MRI can improve accuracy when it comes to predicting survivability of—and potentially guiding care for—patients with high blood pressure in the lungs. 

MRI focuses on heart function of kidney patients receiving dialysis

Researchers at the University of Nottingham were the first to use MRI to study the heart function of kidney patients while they were receiving dialysis treatment.

 
FDA approves Medtronic’s cardiovascular devices and leads for MRI scanning

The U.S. Food and Drug Administration (FDA) approved Medtronic’s cardiac rhythm and heart failure devices and leads to be scanned in 1.5 and 3 Tesla magnetic resonance imaging (MRI) machines.

Phillips Lumify S4-1 transducer brings ultrasound imaging to a smaller device

Royal Philips has received 510(k) clearance from the U.S. Food and Drug Administration (FDA), allowing them to market its S4-1 cardia transducer for Lumify.

Don’t use lung CT for heart care, cardio rads advise

The prospect of leveraging lung cancer CT image data to look for other diseases of the chest is an appealing one, especially in this age of prioritizing value over volume. Indeed, a sound case for wide adoption of the practice has been madeNot so fast, argue three cardiothoracic radiologists in an opinion piece published online Oct. 4 in JACR.
