Ruling out stenosis in patients at low-to-intermediate risk for coronary artery disease tops the list but coronary CT angiography has a much broader role to play.

Achenbach S.

The leading indication for coronary computed tomographic angiography (CTA) is in ruling out coronary stenosis in patients with low-to-intermediate risk for coronary artery disease. Coronary CTA has the potential for broader application, however. This article will explore 10 indications for coronary CTA, dividing them into 3 general categories: ruling out coronary stenosis, establishing the patency of bypass grafts, and resolving questions after cardiac catheterization (Table 1).

Crafting a "Top 10" list is, by definition, a subjective exercise. This list, however, is based on scientific data, knowledge of recent advancements in CT technology, and an understanding of the diagnostic needs of clinicians and patients.
