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.

Imaging agents ID infections from implanted cardiac devices

New findings published in JACC: Cardiovascular Imaging demonstrate how novel imaging tracers can identify infections from implanted cardiac devices (ICDs) before they have to be removed, according to an April 24 article by Cardiovascular Business.

Image reconstruction algorithm, MRI-derived heart strain values can aid prognosis in amyloidosis patients

Recent research found strain parameters taken from a cine MRI-based deformable registration algorithm (DRA) can determine the severity of amyloid buildup in the heart and may provide prognostic information on patients with light-chain (AL) amyloidosis.

Benefit-to-risk ratio of GBCAs remains 'extremely high'—but evaluation should be done for each exam

Despite reports questioning if gadolinium-based contrast agents (GBCAs) can accumulate in the body and lead to adverse health effects, imaging providers should still use them when necessary, according to an editorial published in the Journal of the American College of Radiology.

Automated AI-generated measurements combined with annotated CT images can improve treatment planning and help referring physicians and patients better understand their disease, explained Sarah Jane Rinehart, MD, director of cardiac imaging with Charleston Area Medical Center.

Two advanced algorithms—one for CAC scores and another for segmenting cardiac chamber volumes—outperformed radiologists when assessing low-dose chest CT scans. 

"Gen AI can help tackle repetitive tasks and provide insights into massive datasets, saving valuable time," Thomas Kurian, CEO of Google Cloud, said Tuesday.
