Cardiac CT: Indications and Limitations*

Cardiac CT (CCT) is rapidly evolving as a noninvasive imaging modality. Newer technologic developments in CCT allow the comprehensive assessment of cardiovascular anatomy, includ-ing the coronary arteries. There are special considerations re-garding obtaining and accurately interpreting CCT studies. On completion of this article, the reader should be able to describe the issues related to adequate patient preparation and acquisi-tion and interpretation of CCT studies, recognize specific limita-tions that impair image quality and subsequently the accuracy of diagnosis, and list the current indications and future potential applications of this technique.
