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.

Medical societies release AUC ratings for imaging congenital heart disease patients

The 47-page document, published Jan. 6 in the Journal of the American College of Cardiology, touches on multiple cardiac imaging modalities, rating them based on their appropriateness for examining adults and children with previously diagnosed heart defects.

What’s to Gain from Strain? Experts Say Strain Echocardiography Is on the Path to Acceptance

Despite its diagnostic and prognostic value, speckle-tracking strain echocardiography is underused, some cardiac imagers say. What will it take for adoption to pick up?

CT helps spot patients with potential lead extraction risks

More individuals are receiving cardiac implanted devices than ever before, and as a result, the number of complications stemming from the wire connecting the device to the heart—known as a lead—are also increasing.

New deep learning study brings automated CAC scoring ‘one step closer to clinical translation’

Coronary artery calcium scoring has proven to be more predictive of cardiovascular risk than any other biomarker, but quantifying scores via imaging remains a time-consuming and labor-intensive task.

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.
