目的 提高胸部X线平片和螺旋CT对肺栓塞诊断的认识。材料与方法 经临床确诊 46例肺栓塞的影像学表现进行回顾性分析。结果 胸部X线平片中 70 %病例肺血管纹理改变为肺少血“缺血区” ,呈肺叶、段分布 ;46%病例有肺动脉、肺门动脉增粗 ;3 0 %病例见肺周的浸润灶、纤维索条影及盘状肺不张 ;11%病例胸部X线平片无阳性表现。而螺旋CT阳性率为 10 0 % ,尤其对血管腔内细微病变进行了研究观察。结论 两者各具优缺点 ,两者结合 ,更有利于肺栓塞的诊断和治疗。
Objective To improve the diagnosis of pulmonary embolism by plain radiography and spiral CT. Materials and Methods The clinical manifestations of 46 cases of pulmonary embolism were retrospectively analyzed. Results In 70% of the cases, pulmonary vascular texture was changed to “ischemic zone” in pulmonary blood and blood vessels, with lobular and segmental distribution. In 46% of the cases, pulmonary artery and hilar artery were thickened. Thirty Infiltration stove, fiber optic cable and discotic atelectasis; 11% chest X-ray film no positive manifestations. The positive rate of spiral CT was 10%, especially for intravascular micro-lesions were observed and observed. Conclusion Both have their own advantages and disadvantages, the combination of both is more conducive to the diagnosis and treatment of pulmonary embolism.
