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.

International experts publish research map for GBCAs, gadolinium retention

The special report was created by a group of international researchers, gadolinium-based contrast agent (GBCA) manufacturers and representatives of the FDA at a workshop co-sponsored by the National Institutes of Health (NIH), the Radiological Society of North America (RSNA) and the American College of Radiology (ACR) in February.  

Body scanners proven safe for patients with ICDs, pacemakers

Millimeter wave body scanners—standard security measures at airports, train stations and public buildings since the 2000s—are completely safe for heart patients with implantable devices, German researchers reported at last month’s ESC Congress.

Elastography, echogenicity discriminate plaques in symptomatic stenosis patients

Combining ultrasound elastography and echogenicity analysis may better distinguish between plaques in patients with symptomatic internal carotid artery (ICA) stenosis than in those without symptoms, according to an Aug. 30 study in the American Journal of Roentgenology.

Gadolinium MRI links left atrial fibrosis to high risk of arrhythmias in endurance athletes

Research presented at the 2018 European Society of Cardiology (ESC) annual meeting found that left atrial fibrosis in endurance athletes could increase risk of arrhythmias like atrial fibrillation (AFib), according to an article published Aug. 31 by Cardiovascular Business.

Quicker, cheaper CMR protocol may improve cardio care in developing nations

A streamlined cardiac magnetic resonance (CMR) imaging protocol utilizing a contrast agent allowed Peruvian clinicians to improve care for patients with various heart conditions, a new Journal of the American Heart Association study found. The findings may prove invaluable in bringing CMR imaging to developing regions.
