CTA Coronary Arteries In patients with low to intermediate probability of CAD, multidetector CCTA can be performed for direct coronary artery evaluation. CCTA has been shown to be of value when evaluating patients with CAD because of its high negative predictive value. The use of CCTA has advantages when compared to other testing modalities. CCTA has superior diagnostic accuracy compared to other examinations, may identify high-probability patients The American College of Radiology seeks and encourages collaboration with other organizations on the development of the ACR Appropriateness Criteria through society representation on expert panels. Participation by representatives from collaborating societies on the expert panel does not necessarily imply individual or society endorsement of the final document.

The CRESCENT investigators suggest that the use of CCTA in combination with calcium scoring may allow for a structured protocol that allows a diagnosis to be reached faster with no increase in the referral rate for ICA [20]. The CCTA can also reduce the time to diagnosis and determine which patients need invasive testing [12,13,21- 23].
