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.

William A. Zoghbi, MD, past president of the ACC and ASE, discussed the latest trends in cardiac ultrasound technology. 

An example of a noninvasive coronary CT scan on the left and an invasive angiogram of the same patient on the right from a recent RSNA study. The CT shows more information on the calcified nature of the plaque and shows more anatomical information beyond what the angiogram provides.

Q&A: William Zoghbi breaks down the future of echocardiography

In a new interview, former ACC and ASE President William A. Zoghbi, MD, reviews some of the biggest trends in cardiac ultrasound.

Photon-counting CT boosts image quality and reader confidence in identifying coronary artery disease

The approach outperformed an energy-integrating detector dual-layer CT system and significantly improved image quality, according to a study published in Radiology.
