摘要：目的：探讨16层螺旋CT造影(MSCTA)在冠状动脉狭窄诊 断中的应用价值。方法：26例疑为冠心病的患者，进行16层螺旋CT冠状动脉造影，利 用MPR、CPR、MIP、VR、VE等多种技术进行重建，并将其结果与冠脉造影对比，分析冠状动 脉的狭窄情况。结果：26例患者中，MSCTA图像质量优良率为92.3%；冠状动脉狭窄情况分析 ，以管腔直径减少>50%为诊断标准，发现冠脉狭窄13例，冠状动脉壁钙化18例，管壁欠光滑 20例，管壁充盈缺损4例。结论：多层螺旋CT作为无创性检查手段在冠状动脉狭窄诊断中具 有重要价值。

    Abstract:Objective:To assess the diagnostic value of 16-slice spira l CT angiography (MSCTA) in coronary artery stenosis. Methods:26 patients suspec ted of coronary heart diseases were examined by 16-slice spiral CT scanner, andthen the obtained images were reconstructed by many techniques such as: MPR, CP R, MIP, VR and VE ......
