| 摘 要： | 目的比较不同对比剂方案对冠状动脉成像的影响。方法 60例临床疑诊冠心病患者在行回顾性心电门控64-层螺旋CT冠状动脉造影检查中,根据不同对比剂方案随机分为以下3组:A组(20例)先注射对比剂,后注射生理盐水;B组(20例)先注射对比剂,后注射对比剂与盐水以3∶7比例配制的稀释液;C组(20例)先注射对比剂,后注射对比剂与盐水以1∶1比例配制的稀释液。分别测量所有患者冠状动脉左主干、左前降支、左回旋支及右冠状动脉的CT值。对获自显示冠状动脉、右心室均匀性及左心室壁的数据,利用SPSS13.0软件进行统计学分析与比较。结果在冠状动脉左主干、左前降支、左回旋支测得的CT值以及右心室均匀性显示,各组间均无显著性差异(P>0.05),然而,左心室壁的显示在A、B组之间或A、C组之间均有显著性差异(P=0.0001),在B、C组之间亦有显著性差异(P=0.0007)。结论在64层螺旋CT冠状动脉增强扫描中,稀释对比剂方案优于传统的注射方案(A组),以3∶7比例配制的稀释液(B组)为最佳方案。 |

| Abstract: | Objective To compare the effects of different contrast injection protocols on coronary angiography.Methods According to different contrast injection protocols during coronary angiography by retrospectively ECG-galed 64-slice spiral CT,60 patients with clinically suspected coronary heart disease were randomly divided into following three groups: group A(n=20) was injected by initial contrast medium and subsequent saline;group B(n=20) was injected by initial contrast medium and subsequent a dilute solustion w... |
