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.

AI dramatically reduces radiologists’ rate of missed incidental pulmonary embolism on routine CT

The commercial software also reduced the median detection and notification time for incidental PE in flagged scans from “several days” down to just 1 hour.

Ed Nicol, MD, consultant cardiologist and honorary senior clinical lecturer with Kings College London and president-elect of the Society of Cardiovascular Computed Tomography (SCCT), explained artificial intelligence (AI) in cardiac CT is here to stay and its use is expanding. He noted that one AI-based algorithm is already included in recent cardiology guidelines and more will likely follow. #SCCT

Cardiac imagers need to understand AI as it enters clinical use and ACC guidelines

Most FDA-cleared AI algorithms are related to radiology and cardiology, meaning radiologists and cardiologists need to make an effort to learn how these technologies work.

An example of virtual pulmonary valve implant planning software showing a virtual transcatheter pulmonary valve with measurements implnated in the virtual anatomy of a congenital heart patient. This was part of a training class at the Society of Cardiovascular Computed Tomography (SCCT) 2022 meeting.

FDA makes clearance easier for cardiac device implant simulation software

The FDA is reclassifying interventional cardiovascular implant simulation software into the class II (special controls) regulatory category, which will make it easier for the technology to pass regulatory approval. 

James Udelson, MD, from Tufts and an investiogator in the PRECISE trial, explains how FFR-CT combined with coronary CT outperformed the standard of care in patients with stable chest pain, or low-risk patients with suspected coronary involvement.

Neuroimaging recedes behind other cost compilers in stroke care

Contrary to older research that showed neuroimaging emerging as the single most dominating cost contributor in ischemic stroke care for older Americans, a new study shows treatment and other line items account for bigger slices of the bill.
