New approach to radiation dose reduction during coronary CT angiography

Peer-Reviewed Publication

Cedars-Sinai Medical Center

LOS ANGELES (ALL INFORMATION IS EMBARGOED UNTIL PRESENTED – TIMES INDICATED BELOW) – Researchers at Cedars-Sinai Medical Center’s S. Mark Taper Foundation Imaging Center will make several presentations at the upcoming annual meetings of the American College of Cardiology (ACC) 57th Annual Scientific Session to be held in Chicago, Ill. (March 29 - April 1, 2008).

One key topic will be a novel approach devised by Cedars-Sinai researchers to minimize radiation exposure by up to 75 percent in coronary CTA, while preserving the same diagnostic image quality associated with the standard CTA examination. For symptomatic patients, Cedars-Sinai researchers have developed the “Low-dose Coronary CT Angiogram,” which exposes the patient to full-dose x-rays for only a fraction of the heart cycle. The approach is accomplished without sacrificing the ability to evaluate cardiac function at the same time that the coronary arteries are being viewed. The result is important information for evaluating the presence of potentially life threatening disease while at the same time dramatically reducing radiation exposure.

Among the sessions to be presented by Cedars-Sinai Medical Center’s S. Mark Taper Foundation Imaging Center physicians and researchers:
