目的：研究16层螺旋CT血管造影(CTA)对肺动脉栓塞的诊断价值。方法选取2012年1月-2014年11月门诊及住院部收治的30例肺动脉栓塞患者为研究对象，均行16层螺旋CT血管造影检查，采用容积重建(VRT)、多平面重建(MPR)、最大密度投影(MIP)等技术后处理并分析、评估各分支血管。结果30例肺栓塞患者中25例栓塞的范围、位置、血管狭窄程度等显示清晰，约占83.33%；肺动脉栓塞最直接影像学征象为肺动脉腔内充盈缺损、完全阻塞、血管壁加厚，间接影像学征象包含肺梗死、肺动脉高压、马赛克征、胸腔积液、支气管扩张、右心室、右心房内栓塞等。结论 CTA对肺动脉栓塞的诊断具有迅速、无创、确诊率高等优点，有利于临床医师对治疗方案的制定和疗效的评估。

Objective This paper is to discuss the diagnostic value of 16 slices spiral CT angiography (CTA) on pulmonary artery embolism. Methods Thirty patients with pulmonary artery embolism admitted by the Out-patient Service and In-patient Department from January, 2012 to November, 2014 were selected as research subjects, 16 layers of spiral CT angiography was applied to conduct examination, and the post-processed technology such as volume rendering, multi-plane reconstruction and maximum density projection were applied to evaluate the branch blood vessels. Results The range, location of embolism and narrowing of blood vessel luminal of 25 out of 30 patients with pulmonary embolism were dislayed clearly, accounting for 83.33%approximately, the most direct radiological signs of pulmonary artery embolism included intra-cavity filling defect, complete blocking, blood vessel wall thickening. And the indirect radiological signs included pulmonary infarction, pulmonary hypertension, Mosaic sign, pleural effusion, bronchiectasis and embolism in right ventricle or right atrium, etc. Conclusions CTA delivers rapid and noninvasive advantages with high diagnosis rate in the diagnosis of pulmonary embolism, facilitating the formulation and evaluation of clinical physicians on treatment schemes.
