Noteworthy FDA approvals of the week: Ceiling-mounted CT angiography, AI for brain-adjacent bleeds

Two companies serving medical imagers just had products cleared for marketing in the U.S.

Ron Blankstein, MD, MSCCT, associate director, cardiovascular imaging program, director, cardiac computed tomography, Brigham and Women's Hospital, and professor of medicine, Harvard Medical School, was a co-author on the ACC 2021 Chest Pain Guidelines,[1] which now lists coronary computed tomography angiography (CCTA or CTA) as a 1A level recommendation for front line imaging. He gave an overview of the guidelines during the 2022 Society of Cardiovascular CT (SCCT) meeting in July. #SCCT2022
