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.

Leslee Shaw, PhD, and former presidents of both SCCT and ASNC discusses the role of CT and FFR-CT in the 2021 chest pain guidelines.

VIDEO: Cardiac CT now recommended as a front-line chest pain assessment tool

Leslee Shaw, PhD, director of the Blavatnik Family Women’s Health Research Institute at Mount Sinai Hospital in New York and former president of the Society of Cardiovascular Computed Tomography (SCCT) and the American Society of Nuclear Cardiology (ASNC), explains the role of cardiac computed tomography (CT) in the recent 2021 chest pain guidelines.

The ASNC is one of several medical imaging societies asking Congress to repeal the appropriate use criteria (AUC) criteria mandate. They say it poses issues for clinicians and is becoming outdated by changes in CMS payment systems. The AUC requirements call for documentation using CVMS authorized software in order to show advanced imaging such as nuclear and CT is justified, or else Medicare payments might be withheld.

American Society of Nuclear Cardiology urges Congress to speed prior authorizations, repeal AUC mandate 

Over the past few weeks, members of ASNC’s Health Policy Committee have held meetings with their members of Congress.

Image quality is not an issue for AI model that detects pulmonary embolisms on CT

CTPA is the standard of care for diagnosing PE, but suboptimal scans make it difficult to reach a diagnosis. A new Clinical Imaging study tests the effectiveness of AI when image quality is lacking.
