| 摘 要： | 目的 对比64排螺旋CT(64-MSCT)和高清CT(HDCT)所获得的支架图像质量及支架腔内横截面积。方法 对7例接受冠状动脉支架植入术(10个支架)的患者行HDCT和64-MSCT冠脉支架成像,采用评分法对比两种方法所获支架图像质量,并测量同一支架腔内5个标志点处的横截面积,对测量结果进行统计学分析。结果 64-MSCT获得的支架图像质量总评分低于HDCT,差异有统计学意义(t＝28,P<0.05);64-MSCT图像的支架腔内横截面积均值 小于HDCT图像的支架腔内横截面积均值 ,差异有统计学意义(t=－4.65,P<0.05),偏差百分率为(29.65±13.95)%。结论 HDCT可更清楚地显示支架内部结构,明显降低支架段伪影的影响,是支架植入术后有效的随诊手段。

| Abstract: | Objective To compare the imaging quality and intra-lumen measurement of coronary stent between high definition CT(HDCT) and 64-MSCT.Methods Seven patients after coronary artery stenting(totally 10 stents) underwent HDCT examination.All patients were formerly examined with 64-MSCT coronary angiography.The image quality of coronary artery stent was compared between HDCT and 64-MSCT,and the image scores of coronary stents were obtained.The cross sectional intra-coronary stent lumen area on 5 identical marked p... |
