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.

ACR working with FDA and HHS to help address imaging contrast shortage

The American College of Radiology (ACR) announced this week its government relations staff has been engaging federal agencies in an effort to improve product availability and hasten resolution of the ongoing iodine contrast shortage.

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.
