64排螺旋CT血管成像对冠状动脉病变的筛查作用

目的评价64排螺旋CT血管成像技术对冠状动脉疾病的诊断优势及临床筛查作用。方法回顾性分析126例临床疑有冠心病患者的冠状动脉64排螺旋CT血管成像(MSCTA)检查,行容积再现(VR)、最大密度投影(MIP)、曲面重建(CPR)、高级血管分析(AVA)等多种后处理并结合原始图像进行综合分析。结果126例患者原始横断面图像及重建图像对近端冠状动脉均成功显示,对中远段的显示,原始横断面图像优于重建图像。16例支架置入者显示内支架22只;11例冠状动脉搭桥术后显示桥血管14条;35例MSCTA显示冠状动脉狭窄(>50%)41处,冠状动脉混合性斑块53处,冠状动脉瘤状扩张31处。结论64排螺旋CT冠状动脉重建成像技术为有效可靠的冠心病影像学诊断方法,对病变血管腔狭窄、硬化斑块及内支架、桥血管情况的评价有较高价值,是疑有冠心病患者的首选筛查方法。

64-slice spiral CT angiography for screening coronary artery disease

Objective To evaluate the diagnosis superiority and clinical screening role of 64-slice spiral CT angiography imanes(MSCTA) for coronary artery diseases. Metheds 162 patients who were suspected to suffer from coronary artery heart disease undergone MSCTA were analysis retrospectively. Many postprocessing methods, such as VR,MIP, CPR and AVA, and primitive images were used in Meta-analysis. Results The primitive transection images and reformed images of proximal coronary artery in 162 patients were both disp...
