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.

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.
