Abstract

Despite several limitations, multidetector CT (MDCT) such as 64-slice scanner recently draws attention as the first-line test for the evaluation of chest pain or as a complementary test in patients with equivocal stress test results due to its high negative predictive value and high sensitivity and specificity. In addition, MDCT has the potential as a screening test in asymptomatic patients with a high risk of coronary artery disease. However, the evaluation of in-stent restenosis by MDCT is not infrequently challenging by artifacts caused by metal, especially in smaller stents. In this review, the author will discuss the role of MDCT in patients with suspected coronary artery disease and highlight cardiac MDCT as an emerging diagnostic tool in a routine clinical practice.

  Figure 1. A 52-year-old man with atypical chest pain, but normal treadmill test. (A) Cardiac MDCT shows tight discrete stenosis (90%) at proximal LAD and os area of 1st diagonal branch (arrow). (B) Conventional coronary angiography reveals tight stenosis at the same area (arrow) and is very well correlated with cardiac MDCT
