Computed Tomography

Cardiac computed tomography (CT) has become a primary cardiovascular imaging modality in the past 20 years, and was recommended as a 1A recommendation in the 2021 chest pain assessment guidelines. CT calcium scoring has became a primary risk assessment for coronary artery disease and whether patients should be on statins. Coronary CT angiography (CCTA) is used to for anatomical assessment of the arteries for plaque burden and to identify areas of blockage that may cause ischemia and heart attacks. Additional use of contrast CT perfusion or fractional flow reserve CT (FFR-CT) can offer physiological information on the function of the heart. CT plays a primary role in structural heart assessments for heart valves, repair of congenital defects and left atrial appendage occlusion (LAAO) for both pre-procedure planning and procedural guidance.

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.
