Cardiac Imaging

While cardiac ultrasound is the widely used imaging modality for heart assessments, computed tomography (CT), magnetic resonance imaging (MRI) and nuclear imaging are also used and are often complimentary, each offering specific details about the heart other modalities cannot. For this reason the clinical question being asked often determines the imaging test that will be used.

FDA issues Class 1 recall for 13,000 MRI systems

The FDA placed a Class 1 recall on some MRI systems from GE Healthcare. The recall, which was spurred by employee errors rather than equipment failures, affects almost 13,000 devices.

CT-based calcium score may provide long-term outlook on CAD risk

Researchers evaluating the relative value of long-term forecasts for risk among low-risk patients without coronary artery disease (CAD) found that coronary artery calcium scores derived from CT scans may hold the biggest prediction bang.

Deferred revascularization safe with FFR guidance

On the fence about deferring revascularization? A meta-analysis found similar rates of clinical outcomes when decisions for deferred revascularization in unprotected left main coronary artery stenosis were guided by fractional flow reserve (FFR).

FEVAR pitch: 3D CT cuts radiation exposure

The complexity of fenestrated endovascular aortic repair (FEVAR) makes it a radiation hog, but it may not have to be that way. Using advanced imaging technology, one facility reduced FEVAR’s radiation exposure, contrast usage and procedure time significantly.

Connecting the dots: Brain lesions after CAS may show stroke risk

Brain lesions that appear on diffusion-weighted imaging after carotid artery stenting (CAS) may be a sign of stroke to come. A study in the Feb. 17 issue of the Journal of the American College of Cardiology found patients with lesions on post-intervention magnetic resonance imaging were more than twice as likely to have a stroke or transit ischemic attack in the five years that followed.

ACC examines impact of Medicare changes on imaging

Medicare’s push to link payment for advanced diagnostic imaging to appropriate use criteria and the Medicare Payment Advisory Commission’s site-neutral payment recommendation topped the agenda at the American College of Cardiology’s (ACC) most recent legislative conference.

Demo takes CMR’s pulse as sleuth for microvascular disease

Quantitative cardiac magnetic resonance (CMR) imaging can assess variations in myocardial blood flow throughout the cardiac cycle, making it a potential tool for spotting microvascular diseases.

Acute care echocardiography guidelines offer clarifying insights

Echocardiography recommendations from two professional associations offered a better picture on how cardiologists in the emergency department should and shouldn’t use the technique. The guidelines were published in the February issue of the European Heart Journal.
