摘　　要：目的探讨多层螺旋CT对肺动脉栓塞的诊断价值。方法对40例肺动脉栓塞病人的横断面CT图像结合多种后处理技术进行回顾性分析,全面显示血栓栓子的形态。结果CT横断面图像结合多平面重建、曲面重建、最大密度投影等处理清晰地显示了肺动脉栓塞及栓子形态。其中左、右肺动脉干栓塞49支,叶动脉栓塞105支,段动脉栓塞318支,亚段动脉栓塞292支,能确定的亚亚段肺动脉栓塞为63支。结论多层螺旋CT能很好地显示肺动脉内的血栓栓子及其形态,其对肺动脉栓塞的诊断具有较高的临床价值。Objective To assess the value of multi-slice CT in the diagnosis of pulmonary artery embolism. Methods Data of 40 patients with pulmonary artery embolism were retrospectively analyzed by using varied after-treatment techniques. Results Pulmonary artery embolism and embolus were clearly displayed in cross-section CT pictures with MPR, CPR, and MIP. Conclusion Multi-slice CT can clearly show the position and morphology of embolus in pulmonary artery, which provides a higher value in the diagnosis of pulmonary artery embolism.
