摘　　要：目的研究多层螺旋CT在冠状动脉狭窄诊断中的应用价值及限度。方法52例16层螺旋CT冠状动脉造影,利用MPR、MIP、VR、仿真内镜等多种技术进行重建,分析冠状动脉的通畅情况。结果在严格控制患者适应证的情况下,图像质量优良率为90.4%(47例)。冠状动脉通畅情况分析,以管腔狭窄≥50%为诊断标准,发现冠脉狭窄8例,冠状动脉壁钙化28例,管壁欠光滑30例,管壁充盈缺损6例。结论作为无创检查手段,MSCTA(多层螺旋CT血管造影)在冠状动脉狭窄诊断中具有重要价值。Objective To assess the value and limitation of multi-slice spiral CT in coronary artery stenosis. Methods 52 patients with coronary artery stenosis who underwent coronary artery angiography with a 16-slice scanner, were reconstructed by CPR, MIP, VR, virtual endoscope, the results were compared with catheter angiography. Results Under the strict control of the application syndrome of patients, the rate of fine images in this method was 90.4% （47/52）, analyzing the patency of the coronary artery, and reduction of vessel diameter ≥ 50% was defined as diagnostic criterion, 8 cases showed vessel stenosis, 18 cases were calcified, 30 cases were insufficient smooth, 6 cases were filling defect.Conclusion As a non-hurt diagnosis method, multi-slices spiral CT coronary artery angiography has important diagnosis value for coronary artery stenosis.
