Coronary artery CTA: imaging of atherosclerosis in the coronary arteries and reporting of coronary artery CTA findings.
Invasive coronary angiography remains the standard for assessment of coronary anatomy and pathology, and for determining the extent and severity of coronary lumen obstruction in coronary artery disease. Recent advances in multidetector row computed tomography (MDCT) technology allowing noninvasive imaging of the coronary arteries has led to widespread enthusiasm for the use of noninvasive coronary angiography. A comprehensive and clinically useful MDCT study should incorporate an understanding of the patient history and reason for performance of the test, an overall assessment of study quality, and a complete description of pertinent findings. Because the majority of cardiac computed tomography (CT) studies are now being performed for the evaluation of the coronary arteries and obstructive coronary disease, a clear understanding of what the clinician wants to know from a CTA is critical to its comprehensive interpretation. In this manuscript, we provide an overview of the necessary components of CT coronary angiogram interpretation, from the point of view of the practicing invasive cardiologist.
