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.

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 They say it poses issues for clinicians and is becoming outdated by changes in CMS payment systems.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.

The agency is urging healthcare providers to transition away from these devices and seek out alternatives. It is even working with other manufacturers to try and get similar products on the market as quickly as possible. 

Jeffrey Kuvin, MD, one of the leading voices behind efforts to create a new Board of Cardiovascular Medicine, spoke with Cardiovascular Business about where things stand today.

Half a year after President Biden officially directed federal agencies in the executive branch’s bailiwick to “seize the promise and manage the risks” of AI, the White House has posted a status report.
