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.

Interview with Alan H. Matsumoto, MD, FSIR, FACR, FAHA, professor of radiology, chair of the Department of Radiology at the University of Virginia, vice chair of the American College of Radiology (ACR) Board of Chancellors, and the chairman of the ACR Commission on Interventional and Cardiovascular Radiology. He explains how the ACR and group purchasing organizations are asking the FDA to mitigate the contrast shortage with an emergency use authorization (EUA) to allow non-FDA cleared iodine contrast use.

A comparison between a traditional iodine contrast angiogram (left), and a gadolinium contrast angiogram (right). MRI gadolinium contrast is starting to be used in some interventional radiology procedures and is being considered in interventional cardiology due to the iodine contrast shortage.

Gadolinium can be used as substitute for iodine contrast in some interventional imaging procedures

Gadolinium might be an alternative, stop-gap solution for interventional procedures during the current iodine contrast shortage.

What does radiology have to do with climate change?

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
