ACR Practice Guideline for the Performance and Interpretation of Cardiac Computed Tomography (CT)11 The American College of Radiology, with more than 30,000 members, is the principal organization of radiologists, radiation oncologists, and clinical medical physicists in the United States. The College is a nonprofit professional society whose primary purposes are to advance the science of radiology, improve radiologic services to the patient, study the socioeconomic aspects of the practice of radiology, and encourage continuing education for radiologists, radiation oncologists, medical physicists, and persons practicing in allied professional fields. The American College of Radiology will periodically define new practice guidelines and technical standards for radiologic practice to help advance the science of radiology and to improve the quality of service to patients throughout the United States. Existing practice guidelines and technical standards will be reviewed for revision or renewal, as appropriate, on their fifth anniversary or sooner, if indicated. Each practice guideline and technical standard, representing a policy statement by the College, has undergone a thorough consensus process in which it has been subjected to extensive review, requiring the approval of the Commission on Quality and Safety as well as the ACR Board of Chancellors, the ACR Council Steering Committee, and the ACR Council. The practice guidelines and technical standards recognize that the safe and effective use of diagnostic and therapeutic radiology requires specific training, skills, and techniques, as described in each document. Reproduction or modification of the published practice guidelines and technical standards by those entities not providing these services is not authorized.

Cardiac computed tomography (CT) is an evolving modality that includes a variety of examinations to assess the anatomy and pathology of the cardiac chambers, valves, myocardium, coronary arteries and veins, pericardium, aortic root, and central great vessels. The development of multidetector CT scanners with increasing numbers of detector rows, narrow section thicknesses, increasing scanner speeds, the ability for electrocardiographic gating, and radiation dose modulation allows the performance of CT coronary arteriography. Computed tomography coronary arteriography enables the assessment of multiple types of cardiac pathology, including intraluminal coronary arterial plaque formation, coronary artery stenosis, congenital anomalies, coronary artery aneurysms, sequelae of cardiac ischemia, and the assessment of prior vascular interventions, while providing information about cardiac and valvular function. Noncardiac structures included in cardiac CT examinations must also be evaluated. This guideline attempts to maximize the probability of detecting cardiac abnormalities with cardiac CT. American College of Radiology requirements for physicians and personnel performing examinations are also addressed and will become applicable by July 1, 2008.
