摘　　要：目的:探讨螺旋CT对肺栓塞的诊断价值。方法:回顾性分析15例肺栓塞患者CT平扫及增强扫描表现。结果:15例平扫显示片状实变影、磨玻璃影、楔型影、“马赛克”征等。增强扫描中央型肺栓塞12例,周围型肺栓塞3例;中央肺动脉扩张10例;右心室增大7例;支气管动脉显示15例,其中扩张6例;支气管静脉显示并扩张1例;根据肺动脉内栓子形态分4类。结论:CT对肺动脉栓塞具有较高的诊断价值。Objective：To explore the value of spiral CT in the diagnosis of pulmonary embolism （PE）. Methods： 15 cases of plain CT and contrast enhancement （CE） CT manifestations were analysed retrospectively. Results： Patchy consolidation, ground glass opacity, wedge-shaped shadow, ＂mosaic oligemia＂ etc can be seen on plain CT. On CE CT scan, the central pulmonary embolism is found in 12 cases, the peripheral pulmonary embolism is found in 3 cases; The dilatation of central pulmonary arteries is found in 10 cases; Enlargement of right ventricle is found in 7 eases; The bronchial artery appears in 15 cases, among them dilates in 6 cases; The bronchial vein appears and dilates in 1 case. The emboh axe divided into 4 kinds according to the shapes. Conclusion： CT is of high value in the diagnosis of ptdmonary artery embolism.
