Cardiac computed tomographic angiography (CCTA) is a unique diagnostic modality that can provide a comprehensive assessment of cardiac anatomy. Rapid advances in scanner and software technology have resulted in the ability to noninvasively image the coronary arteries. However, careful patient preparation and scanning technique is required to ensure optimal image quality while minimizing radiation dose delivered. Important components of patient preparation include knowledge of the indications and contraindications for CCTA, patient screening, patient premedication, patient positioning, prescan instruction, and electrocardiograph lead placement. Scanning technique should be determined on a patient by patient basis and tailored according to age and radiation risk, body mass index and chest circumference, heart rate and variability, presence of stents, and coronary calcification.
