摘　　要：目的:探讨肺动脉栓塞多层螺旋CT动态增强扫描的CT征象及对临床的诊断价值。方法:搜集经多层螺旋CT动态增强扫描确诊的肺动脉栓塞27例,根据其CT影像资料,重点分析肺动脉栓塞指数、中央肺动脉受累比例、有无支气管动脉扩张显示、是否并肺梗死。结果:27例肺动脉栓塞患者,中央肺动脉受累15例(55.6%),支气管动脉扩张4例(14.8%),发生肺梗死12例(44.4%)。12例发生肺梗死的肺动脉栓塞指数平均46%,15例非肺梗死的肺动脉栓塞指数平均21%,栓塞指数比较差异有显著性(P<0.05)。结论:多层螺旋CT动态增强扫描能清楚地显示肺动脉栓塞的程度及范围,对评价病情、指导治疗和估计预后具有重要的临床价值。Objective： To investigate the clinical value of spiral CT dynamic contrast enhanced scanning on pulmonary embolism. Methods： To collect and analyze the appearance in muhislice spiral CT of 27 patients with pulmonary embolism. According to the CT image information, to study the embolismic index, the involved proportion of central pulmonary artery, the presenting proportion of bronchodilation and pulmonary infarction especially. Results：In the 27 patients with pulmonary embolism, 15 cases were involved in central pulmonary artery （ 55. 6 % ） and 4 cases with dilated bronchial artery（ 14. 8% ） , 12 cases with puhnonary infraction （ 44. 4% ） whose average puhnonary embolismic index was 46% , other 15 cases with no pulmonary infraction whose average embolismic index was 21% , and there was significant difference between the two groups （ P 〈 0. 05 ）. Conclusion：Multislice spiral CT dynamic contrast enhanced scanning can well show the image appearance, it is an effective method for pulmonary embolism to evaluate the prognosis and direct the treatment methods.
