摘要
目的探讨多层螺旋CT肺血管造影在肺动脉栓塞中的诊断价值。方法回顾性总结分析2011年1月～2013年1月我科经64层螺旋CT扫描并经临床确诊的肺动脉栓塞患者的临床资料。结果 40例肺栓塞患者64层螺旋CT扫描显示共累及肺动脉580支,PE的直接征象分为中心型64支(占11.0%),附壁环型215支(占37.0%),偏心型187支(占33.0%),闭塞型114支(占20.0%)。肺动脉栓塞的间接征象的CT表现为肺纹理稀疏,局部肺密度下降,肺梗死灶形成,肺动脉高压和胸腔积液。结论 64层螺旋CT具有扫描用时短、图像清晰、三维重建方便等优势,已经成为检查肺动脉栓塞的首选方法之一,值得广泛推广和应用。
Objective To investigate the value of multi-slice spiral CT pulmonary angiography in the diagnosis of pul- monary embolism. Methods We retrospectively analyzed the clinical data from January 2011 to January 2013 by spiral CT scan and clinically diagnosed in patients with pulmonary embolism. Results The 40 cases of pulmonary embolism in patients with CT scan display total pulmonary involvement 580, PE of direct signs were divided into the central type 64（11.0%）, mural ring 215（37.0%）, the eccentric 187（33.0%）, occlusion of 114（20.0%）. Indirect signs of pulmonary embolism CT showed markings sparse local decline in lung density, the formation of pulmonary infarction, pulmonary hypertension, and pleural effusion. Conclusion Multi-slice CT has a short scanning, image clarity, has become one of the preferred method of inspection pulmonary embolism, should be popularized and applied.
