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.

Radiologist Michael Morris, MD, radiologist and director of cardiac CT and MRI at Banner Health, explains how cardiac radiology imaging is moving toward expanded use of fractional flow reserve CT (FFR-CT) and artificial intelligence analysis of coronary CT angiography (CCTA) exams as a standard of care. He spoke to Radiology Business during RSNA 2025.
