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.

Chest imaging in the ED has increased substantially over the last 20 years

A multi-institutional team of researchers found that emergency department (ED) utilization of chest imaging has grown substantially in the U.S. over the last two decades and is likely due to an increased availability of CT scanners and increased pressure on ED physicians to rapidly triage patients, according to a study published Jan. 2 in the Journal of the American College of Radiology.

Physician radiation exposure increases during angiography for obese patients

Physicians performing coronary angiography on obese patients are exposed to seven times the amount of radiation than when they performed the procedure on those with a normal body weight, according to a Jan. 2 study published in Circulation: Cardiovascular Interventions.

Imperial College London partners on AI, imaging to ramp-up drug discovery for heart disease

Researchers from Imperial College London are teaming up with Bayer Pharmaceuticals to see if artificial intelligence (AI) could accelerate the discovery of new, effective drugs for cardiovascular disease and other heart-related conditions, according to a recent news release.

CTA offers efficiency, lower costs in patients with suspected CAD

A team of international researchers found using coronary CT angiography (CCTA) to determine which patients with suspected coronary artery disease (CAD) would benefit from invasive angiography can reduce costly invasive procedures while achieving similar accuracy to other methods.

Corotid biomarker may personalize treatment in patients with CVD risk factors

Carotid pulse wave velocity (PVW) measured with ultrafast ultrasound at the end of systole (PWV-ES) may be a better biomarker of carotid stiffness in diabetic patients than PWV measured at the beginning of systole, according to a new study.

3D printing workflow utilizes CT scans to improve aortic valve replacement

With the development of a new three-dimensional (3D) printing workflow, researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University in Boston may help cardiologists produce more proficient implantable heart valves and determine how different sized valves interact for each patient before surgical intervention for aortic valve replacement, according to a Dec. 10 report by the 3D Printing Media Network.
