Computed Tomography

Computed tomography (CT) is a fast and accurate imaging modality often used in emergency settings and trauma imaging. CT scans, with or without (or both) iodinated contrast are frequently used to image the brain, chest, abdomen and pelvis, but also have post-imaging reconstructive capabilities for detailed orthopedic imaging. It is now a standard imaging modality in emergency rooms to quickly assess patients. CT uses a series of X-ray images shot as the gantry rotates around the patient. Computer technology assembles these into into a dataset volume than can be slices on any access, or advanced visualization software can extract specific parts of the anatomy for study.

Eric Williamson, MD, MSCCT, the president of the Society of Cardiovascular Computed Tomography (SCCT) and professor of radiology at Mayo Clinic, explains how the iodine contrast shortage is causing issues for cardiac CT imaging. He discusses ways imagers can stretch they iodine contrast supplies and some technologies that might help conserve contrast. #contrastshortage
