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.

Coronary calcium scans may push some to adopt healthy heart habits

Jane E. Brody, a personal health columnist for the New York Times, recalled a time a few years back when her brother decided to request a calcium heart scan that, fortunately, didn't reveal any major problems. Still, the memory prompted her to pen a column about the noninvasive imaging technique.

MRI shows liver fibrosis may be linked to cardiovascular disease

In a multiethnic cohort study published March 9 in Circulation: Cardiovascular Imaging, researchers found liver fibrosis may be strongly associated with a patient's history of heart failure, atrial fibrillation or coronary heart disease.

New quantitative flow ratio method tops FFR in diagnosing heart blockages

A team of international researchers showed that quantitative flow ratio (QFR) was feasible for testing coronary artery stenosis, and more accurate compared to traditional wire-based fractional flow reserve (FFR), according to a study published in Circulation: Cardiovascular Imaging.

AI model 98% accurate in echocardiogram classification—outperforming cardiologists

A study published in the journal Digital Medicine found a trained artificial intelligence (AI) platform classified echocardiogram views with 98 percent accuracy—outperforming board-certified cardiologists.

New method may improve fractional flow reserve CT accuracy

A recent study published in the April 2018 issue of Radiology optimized a four-step approach to accurately detect hemodynamically significant intermediate-stenosis lesions, which outperformed coronary CT angiography. Researchers also found using coronary contrast opacification variations to estimate blood flow distribution may improve CT fractional flow reserve accuracy.
