Newswise — Use of the imaging technique known as cardiac computed tomography (CT) angiography (CCTA) has the potential to expose patients to high doses of radiation, and methods available to reduce radiation dose are not frequently used, according to a study in the February 4 issue of JAMA.
The 64-slice (able to scan 64 images per rotation) CCTA has emerged as a useful diagnostic imaging method for the assessment of coronary artery disease and has been proposed to be useful for evaluating patients in emergency departments with chest pain. “With the constantly increasing number of CCTA-capable scanners worldwide, the volume of CCTA scans performed is likely to show substantial further increase,” the authors write. They add that the clinical usefulness of CCTA for the assessment of coronary artery disease has to be weighed against the radiation exposure of CCTA and the small but potential risk of cancer. Many clinicians may still be unfamiliar with the magnitude of radiation exposure that is received during CCTA in daily practice and with the factors that contribute to radiation dose, according to background information in the article.
