摘　　要：目的：评价128层螺旋CT对肺栓塞的临床应用价值。方法：采用触发扫描技术对32例临床怀疑肺栓塞患者行128层螺旋CT肺动脉造影检查，所得容积数据传送至工作站后分别行多平面重建（MPR）、最大密度投影（MIP）、容积再现（VR）成像。结果：32例患者中，经临床及实验室检查并随访确诊者18例，128层螺旋CT肺动脉造影检出18例，其中肺动脉主干栓塞1支，左右肺动脉栓塞3支，叶肺动脉栓塞23支，段肺动脉栓塞67支。肺栓塞的直接征象为管腔狭窄、阻塞、分支减少及血管腔内的低密度充盈缺损，间接征象为肺梗死灶形成、胸腔积液、肺动脉高压等。结论：128层螺旋CT肺动脉造影能够及时、准确、直观地显示栓子部位，是肺栓塞安全、迅速、无创的有效诊断方法。Objective ：To evaluate the diagnosis value of 128 slice spirl Computed Tomography Angiography in pulmonary em- bolism. Methods ：32 suspected Pulmonary embolism patients were examined by technique that concentrateion of contrast medium controls the scanning of 128 slice spiral CT. Volume data was transmitted to the work station and the reconstruction of multiplanar reformations（MPR） ,maximum intensity projection（MIP）,volume rendering（VR） was done . Results ：The direct signs of Pulmo- nary embolism were luminal constriction,emphraxis, branched decreased,intraluminal low D filling defect of blood vessel;while the indirect signs were formation of pulmonary infarction focus, pleural effusion, pulmonary hypertension, etc. Conclusion： 128 slice spirl CTPA plays an important role in the vivid recognition of thrombosis and sites of thrombosis. This is a safe,quick and non--in- vasive imagilogic examination for Pulmonary embolism .
