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.

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.

Cardiac CT soft plaque assessment may offer paradigm shift for coronary disease screening

New artificial intelligence software that can evaluate coronary CT scans to automatically assess soft plaques were by far the biggest technology advance discussed at the Society of Cardiovascular Computed Tomography (SCCT) 2022 meeting.

Substituting iodinated contrast media in patients with a history of ICM reactions reduces risk by 61%

“For patients with a prior ICM-induced hypersensitivity reaction, healthcare providers must balance the benefit of ICM reuse against the risk of a repeat reaction,” authors of a new meta-analysis published in Radiology said.

Generic CT contrast supplier pledges ‘immediate relief’ from shortage

A global tech and pharma vendor is set to inject U.S. healthcare with a set of generic contrast agents, the first of which will be an FDA-approved substitute for GE Healthcare’s Visipaque.
