心血管计算机断层扫描采用了最近发布的切片技术，提高了空间分辨率，减少了采集次数和切片厚度。我们研究了层螺旋CT与导管血管造影的准确性。研究对象66例，均在30天内接受了层螺旋CT和导管血管造影检查。对于狭窄50%的病变，可解释图像的准确性为94%，敏感性为95%，特异性为96%，阳性预测值为97%，阴性预测值为92%。在静脉移植物的评价中，我们发现层螺旋CT与插管100%符合(9/9)。这些指标比16层螺旋CT有了很大的改进，支持层螺旋CT作为一种可靠的诊断工具。(C)2006 Elsevier Inc.保留所有权利。
Cardiovascular computed tomography (CVCT) with the recently released 64-slice technology increases spatial resolution and decreases acquisition times and slice thickness. We investigated the accuracy of 64-slice CVCT in relation to catheter angiography. We studied 66 sequential subjects who underwent 64-slice CVCT and catheter angiography within 30 days. Accuracy results were 94% for interpretable images, 95% for sensitivity, 96% for specificity, 97% for positive predictive value, and 92% for negative predictive value for lesions with > 50% stenosis. We found 100% agreement between 64-slice CVCT and catheterization among vein graft evaluations (9 of 9). These metrics are vastly improved from the 16-slice generation and support 64-slice CVCT as a reliable diagnostic tool. (C) 2006 Elsevier Inc. All rights reserved.
