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.

Novel imaging approach IDs CAD without the risk of a contrast agent

Researchers at Beth Israel Deaconess Medical Center in Boston have developed an imaging technique that allows physicians to diagnose CAD without the risk of a contrast agent.

The economic impact of MR on heart failure patients

Newly diagnosed HF patients with concomitant mitral regurgitation can expect more admissions, longer hospital stays and pricier medical bills than HF patients without MR, according to an analysis published in the American Journal of Cardiology.

How researchers are using patient selfies to monitor blood pressure

A study published this week in Circulation: Cardiovascular Imaging details how one Canadian scientist and his team are using 2-minute video selfies to track patients’ blood pressure.

Medtronic, Viz.ai partner to improve LVO stroke detection

Medtronic and Viz.ai, an AI-driven tech company, have joined forces to promote the adoption of imaging software that could drastically cut the time it takes physicians to identify suspected large vessel occlusion.

Around the web

Several key trends were evident at the Radiological Society of North America 2024 meeting, including new CT and MR technology and evolving adoption of artificial intelligence.

Ron Blankstein, MD, professor of radiology, Harvard Medical School, explains the use of artificial intelligence to detect heart disease in non-cardiac CT exams.
