摘　　要：目的研究多层螺旋CT肺血管造影在肺动脉栓塞诊断中的诊断价值。方法对18例经16层螺旋CT确诊的肺栓塞患者进行回顾性分析。结果 18例患者共累及224支肺动脉及其分支,其中肺动脉干1支,左、右肺动脉共9支,叶动脉45支,段动脉78支,亚段动脉及以下动脉分支91支。肺栓塞的CT表现:①直接征象:中心型充盈缺损、偏心型充盈缺损、附壁血栓、完全阻塞型充盈缺损。②间接征象:肺野透过度增高,肺纹理稀疏、细小,肺动脉高压,肺梗死,主、肺动脉增宽,右心室增大,心包积液、胸腔积液等。结论多层螺旋CT肺血管造影是诊断肺动脉栓塞的一种快捷、无创、安全、可靠的影像诊断方法,对及时诊断和治疗肺动脉栓塞有重要的临床意义。Objective To study the role of pulmonary angiography with muhi-slice spiral in the diagnosis of pulmonary embolism （PE）. Methods 18 cases of pulmonary embolism diagnosed with MSCT were retrospectively analyzed. Results There were 224 pulmo-nary artery and artery branches involved in 18 cases of pulmonary embolism. Of them,there were 1 embolism in main pulmonary arteries trunk,9 in left/right pulmonary artery,45 in lobular arteries branch,78 in segmental branch, and 91 in subsegmental branch. The direct CT manifestations of pulmonary embolism were various types of intra-luminal filling defects. Secondary CT signs included higher diaphaneity of lung, reduced pulmonary vascular markings, pulmonary hypertension, pulmonary infarction, dilatation of the pulmonary artery, enlargement of the right ventricle,pleural effusion and pericardial effusion. Conclusion Multi-slice spiral CT pulmonary angiography is noninvasive, quick, and highly sensitive for the diagnosis of pulmonary embolism, and it has high clinical value in the early diagnosis and treatment of pulmonary embolism.
