摘　　要：目的评价多排螺旋CT肺动脉造影在肺动脉栓塞中的临床应用价值。方法对10例行多排螺旋CT肺动脉造影检查的肺动脉栓塞的影像表现进行回顾性分析。用双排螺旋CT扫描,行胸部平扫及增强扫描,并进行图像后处理,获得肺动脉多平面重建图像。结果10例中肺动脉主干、左右肺动脉及叶段肺动脉的显示率为100%,直接征象包括肺动脉腔内充盈缺损和完全阻塞,间接征象为肺梗塞、胸腔积液、心包积液、肺动脉高压。结论多排螺旋CT肺动脉造影诊断肺动脉栓塞安全、准确、无创,且对治疗后疗效的评价有重要的价值。Objective To evaluate the clinical value of muti-slice spiral CT pulmonary arteriography in diagnosing pulmonary embolism. Methods The image manifestation of 10 cases of pulmonary embolism examined by mulit-slice spiral CT were analyzed retrospectively. Plain scans and contrast enhanced scans were performed by two-slice spiral CT and images were restructed with MPR. Results The main pulmonary artery and right or left pulmonary artery could be displayed in the all 10 cases. The direct signs included filling defect and obstruction in pulmonary artery, and the indirect signs included pulmonary infarction, pleural effusion, pericardial effusion and pulmonary artery hypertension. Conclusion Multi-slice spiral CT pulmonary arteriography is safe, exact and atraumatic, and it is of importamt value in evaluating curative effect.
