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。Objective：To assess the diagnostic value of 16-slice spiral CT angiography（MSCTA）in coronary artery stenosis.Methods：26 patients suspected of coronary heart diseases were examined by 16-slice spiral CT scanner,and then the obtained images were reconstructed by many techniques such as：MPR,CPR,MIP,VR and VE,etc.The results were compared with the conventional coronary artery angiography to assess the stenosis.Results：In 26 pa- tients,the rate of fine image in this method was 92.3%.Coronary stenosis was defined as lumen diameter reduction≥50%,13 cases showed vessel stenosis,18 cases were calcified,20 cases were insufficient smooth,4 cases were filling defect.Conclusion：The non-invasive technique of MSCTA for examining the coronary artery appears to be a useful method for detecting coronary artery stenosis.
