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.

Emergency CCTA: As good as traditional testing and no more demanding of resources

Three major trials have already established the 30-day clinical and economic soundness of ordering coronary CT angiography in evaluations of patients who show up in the emergency department complaining of chest pain. A new study shows the CCTA pathway to be similarly strong at the 12-month mark. 

FDA clears Vue Motion universal viewer for ECG waveform readings

The FDA cleared Carestream’s Vue Motion universal viewer on Oct. 8 for diagnostic reading of ECG waveforms on desktop computers and mobile tablets.

Myocardial perfusion imaging has low yield for detecting ischemia in AF patients

An analysis of patients with atrial fibrillation at the Cleveland Clinic found the yield of using myocardial perfusion imaging for detecting ischemia was low and did not significantly increase with increasing cardiovascular risk. Ischemia was not associated with mortality, either.

Risk of radiotherapy upsetting implantable heart devices: It’s all about the neutrons

When implantable heart-help devices malfunction in cancer patients undergoing non-neutron-producing radiation therapy, don’t blame the malfunction on the therapy. 

CT angio in an academic ED: So many incidental findings, too few follow-ups

Emergency physicians at one large teaching hospital performed 370 computed tomography angiography (CTA) exams for suspected aortic dissection in calendar year 2014. Almost 89 percent came back with at least one incidental finding. More than one-fourth were deemed clinically significant. 

Big data, 4D, ‘beamforming’ beef up ultrasound heart imaging in Milwaukee

A Milwaukee hospital says it has become the first in the world to use 4D cardiovascular ultrasound to crisply image intricate parts of the heart and, in the process, to circumvent the use of common but often inconclusive transthoracic echocardiograms (TTEs).

Noninvasive stress testing varies considerably following PCIs at VA hospitals

An analysis of veterans undergoing PCIs at Veterans Affairs (VA) hospitals across the U.S. found the rates of noninvasive stress testing following the procedures varied considerably. The frequency of stress testing was not significantly associated with all-cause mortality or MI.

Signs of self-referral?: MR and CT usage for peripheral arterial disease low among cardiologists

In the diagnosis of peripheral arterial disease, MR angiography (MRA) and CT angiography (CTA) have replaced diagnostic catheter angiography (DCA), as evidenced by the drop in DCA utilization among radiologists. However, while utilization of DCA has fallen among radiologists, overall utilization has remained steady, bolstered by a sharp rise in utilization among cardiologists and surgeons.

MRI detection of intraplaque hemorrhage is cost-effective strategy for judging stroke risk

Using MRI to look for intraplaque hemorrhage could be a cost-effective way to inform treatment decisions in those with asymptomatic carotid artery stenosis (CAS), according to a decision-making analytic model described in a study published online in Radiology.

Risk of aneurysm recurrence suggests need for longer MR follow-up

While endovascular treatment (EVT) of intracranial aneurysm is generally effective at preventing long-term bleeding, a clinically relevant percentage of patients will experience a late recurrence, suggesting a need for MR angiography follow-up for select patients for 10 years or more, according to a French study published online in Radiology.
