【摘要】Objective To determine the accuracy of 64-slice spiral computer tomography in the diagnosis of coronary artery lesions. Methods We retrospectively collected the coronary artery imaging data of 120 patients with known or suspected CAD hospitalized in our ward during July 2006 and May 2009. Each patient underwent 64-slice CTA and conventional catheter-based selective coronary angiography ( SCA) within 2 weeks which served as gold standard. For the analysis of MSCT and CAG, the coronary artery tree was broken down into 16 segments after a modified American Heart Association (AHA) classification and all segments were analysed individually. A luminal narrowing of > 50% based on visual estimation was considered significant in both modalities. The diagnostic accuracy of 64-slice spiral CTA was expressed as sensitivity, specificity, positive predictive value and negative predictive value. Results Out of a total of 1920 coronary artery segments, 1857(97% )were visible by MSCT and CAG simultaneously. The CTA had a sensitivity, specificity, positive predictive value, negative predictive value and diagnose accordance rate of 89% ,98% ,85% ,98% and 97% , respectively. Conclusion 64-slice MSCT has a good diagnostic accuracy
