OBJECTIVES: The aim of this study was to determine the diagnostic accuracy of 16-slice multislice spiral computed tomography (MSCT) of the coronaries and to provide data in a real clinical setting. Previous 16-slice MSCT studies presented data excluding @entity1 with @entity730 , vessels of < 1.5 or 2 mm, and segments with impaired image quality. By including these data for 16-slice MSCT, a direct comparison with new data from 64-slice MSCT is possible. METHODS AND RESULTS: Sixty two @entity1 with suspected or known @entity453 ( @entity453 ) were prospectively enrolled and underwent computed tomography angiography (CTA) and invasive coronary angiography (ICA). All vessels were evaluated for the presence of a significant @entity3979 (>50%) using the @entity299 ( @entity299 ) 15-segment model. From the evaluation of 917 segments, sensitivity, specificity, and positive and negative predictive value (NPV) (positive predictive value [ @entity2286 ] and NPV) for the presence of relevant @entity3979 were 73, 98, and 71 and 98% per segment and 94, 90, and 91 and 93% per @entity1 , respectively. The influence of age, gender, body surface area (BSA), heart rate (HR), stents, and @entity141 -score value was analyzed. High @entity141 -score values were the only statistically significant predictor for impaired diagnostic accuracy. CONCLUSIONS: In summary, CTA with evaluation of all vessel segments in a broad spectrum of @entity1 allowed accurate and fast noninvasive coronary artery evaluation, including evaluation of stented segments. These data are very similar to those published recently for 64-slice scanners.
