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.

Experts highlight early ischemic signs on CT that can estimate onset of stroke

Experts involved in the research believe their findings could help to guide providers in making treatment decisions. 

CT coronary artery calcium (CAC) scoring, also known as the Agatston score, to assess the risk a patient has for future heart attacks and help decide if a patient requires statins.

Example of a patient's coronary tree extracted from a cardiac CT scan. CT allows very detailed anatomical imaging and now physiological and plaque information that can be useful in pre-planning interventional procedures. Imaging from the GE Revolution Apex system at SCCT 2022.

VIDEO: CT imaging to plan coronary interventions — Interview with Jonathon Leipsic, MD

Jonathon Leipsic, MD, chairman of the Department of Radiology, University of British Columbia, explains how noninvasive computed tomography angiography (CTA) can be used to aid in planning interventional cardiology procedures for percutaneous coronary intervention (PCI) and chronic total occlusions (CTO).

CT imaging alone found noninferior to CT/MR combo for acute ischemic stroke patients

“The value of MRI added to CT in patients such as these should not be presumed."

FDA clears AI assessor of stricken dense brain tissue

An AI startup has received the FDA’s go-ahead to market a new tool within its existing platform that automatically diagnoses stroke and brain injury in hyperdense brain tissue imaged with unenhanced CT.

FDA temporarily approves importation of a second foreign-labeled iodinated contrast media

Bracco Diagnostics, Inc has been given the go ahead by the U.S. Food and Drug Administration to temporarily import Iomeron (iomeprol injection) into the U.S. market amid the ongoing iodinated contrast media shortage.
