摘要
目的评价多层螺旋CT肺动脉造影在肺栓塞中的临床应用价值。方法23例拟诊肺栓塞患者行多层螺旋CT肺动脉造影，在工作站上对原始薄层图像进行后处理观察肺动脉栓子分布情况。结果全部病例三维肺血管图像均能充分显示肺动、静脉的空间关系与解剖细节，不但能准确、直观地观察肺血管，而且能明确诊断肺动脉栓塞及有无侧支循环形成。23例患者中检出肺动脉栓塞16例，共发现肺动脉栓子264处，其中段及段以上栓子149处，亚段及以下5～6级分支115处，血栓栓塞血管直径最小者1mm。结论多层螺旋CT肺动脉造影对肺动脉主干、亚段及以下5～6级分支肺栓塞具有很好的应用价值。
Objective To evaluate the clinical value of pulmonary vessels with multi slice spiral CT pulmonary angiography（MSCTPA） in pulmonary embolism（PE）. Methods MSCTPA was performed in 23 cases suspected patients. All the primitive images of pulmonary vessels were produced at the console workstation. The distribution of pulmonary vessels emboli was evaluated from different angle. Results Spatial relationship and anatomical details of pulmonary arteries and veins could exactly be shown on all pulmonary vessels three-dimenslonal images in above-mentioned patients. On the basis of MSCTPA, PE could be diagnosed definitely, in addition, collateral circulation formation could be clearly demonstrated. Of 23 patients, PE were found in 16 cases by MSCTPA. Two hundrends and sixty-four emboh were demonstrated in total, among which there are 149 emhokukicated in segmental ateries and 115 in subsegmental ateries（ grade 5- 6 branches）. The minimal diameter of pulmonary atery with thrombus was 1mm. Conclusion MSCTA has very high clinical value in detecting segmental and subsegrnental pulmonary thrombi in PE patients, and provides useful information for the diagnosis and treatment of pulmonary vascular diseases.
