BACKGROUND: The @entity453 , now, the incidence is increasing in both developed and developing countries. The investigation is evoluted and non-invasive multislice CT scanners have been used more frequently, although the gold standard is still the coronary angiography. OBJECTIVE: To investigate the accuracy in detected @entity453 by using 16-slice CT scanners compared to the conventional coronary angiography. MATERIAL AND METHOD: Fifty-five @entity1 were 43 males, 12 females, median aged 62 years (43-82 years), and average heart rates 67 beats/minute (46-147 beats/minute) had the ECG-gated CT angiography followed by coronary angiography in 3 months. The ECG-gated CT angiography was performed by using 16-slice MSCT detector (0.42-s rotation time, 16 x 0. 75-mm detector collimation). RESULTS: All @entity1 were classified into two major groups; one was significant @entity3979 which was designed by @entity850 at least 50% and the other was non-significant @entity850 which was designed by normal or @entity850 less than 50%. The site having blooming artifact due to calcification that causes complete obliteration of the lumen or having significant motional artifacts was ruled out. There were 285 evaluable sites in 19 @entity1 with high heart rates, more than 70 beats/minute. The sensitivity, specificity, and accuracy in significant @entity850 were 72.9%, 99.6%, and 94.0% respectively. In 36 @entity1 with a lower heart rate, there were 563 evaluable sites, the sensitivity was 86.5%, specificity was 98.5%, and accuracy was 96.6%. The overall showed 81.1% of sensitivity, 98.9% of specificity, and 95.8% of accuracy. CONCLUSION: The accuracy of the 16-slice CT angiography for @entity1 suspected of having @entity453 was high. However, blooming artifacts from the @entity460 , respiratory artifacts, and small size of the distal and branching artery still caused limited luminal assessment. These problems have challenged the new coming generation of MDCT.
