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.

For almost nine years since the adoption of the Protecting Access to Medicare Act (PAMA) established the requirement for appropriate use criteria (AUC) to receive payment for advanced diagnostic imaging, the American Society of Nuclear Cardiology (ASNC) has lobbying Congressional leaders change or repeal AUC mandate. Those efforts have paid off in the 2024 Medicare Physician Fee Schedule final rule, where AUC program has been paused and all of its regulations were rescinded. Photo by Dave Fornell.
