目的：探讨多层螺旋CT肺动脉造影及多方法三维重建技术在肺栓塞诊断中的临床价值。材料与方法：回顾性分析我院2007年1月-2010年5月临床拟诊为肺栓塞,并经16层螺旋CT肺动脉造影及多平面重组（MPR）、容积再现（VRT）、最大密度投影（MIP）多方法三维重建确诊的41例病例。结果：41例病例均得到满意图像,CT肺动脉造影对肺动脉主干、左右肺动脉干及叶、段、亚段肺动脉显示良好,41例病例共发现栓子512个,其中肺动脉主干2个,右肺动脉干63个、左肺动脉干54个、叶动脉105个、段及亚段288个。直接征象表现为各级肺动脉内不同形态的充盈缺损,间接征象表现为因肺动脉栓塞所致的肺梗塞、肺动脉高压、支气管动脉扩张、右心功能不全及局限性的肺纹理稀疏、胸腔积液等的影像学表现。结论：多层螺旋CT肺动脉造影及多方法三维重建技术安全、迅速、无创、敏感性、特异性、分辨率高可作为临床诊断肺栓塞及复查疗效的首选影像学方法。

Purpose：To evaluate the clinical value of pulmonary angiography with multi-slice spiral CT in the diagnosis of pulmonary embolism（PE）. Materials and Methods：41 patients with clinically suspected PE underwent multi-detector CT pulmonary angiography and post-processing,such as maximum intensity projection（MIP）,volume rendering technique（VRT）and multiplanar reformation（MPR）,subsequently synthetical analysis. Results：The pulmonary artery main trunk,left and right pulmonary arteries trunk,lobar arteries,segment arteries,and deuto-segment arteries were displayed clearly in all cases.Of the 41 patient s with PE,altogether 512 emboli were detected by CT pulmonary anigogrpahy.2,63,54,and 105 emboli were detected in pulmonary artery main trunk,right pulmonary artery trunk,left pulmonary trunk,lobar arteries,respectively.288 emboli were demonstrated in segment and deuto-segment arteries.The direct sign of PE was filling defect in different degree and the indirect signs included lung infraction,pulmonary hypertension,bronchial arteries ectasia,right ventricle functional defect,localized pulmonary markings raritas,and pleural effusion. Conclusion：Multi-slice spiral CT pulmonary angiography is non-invasive,fast,highly sensitive and maybe the first choice for diagnosis of PE.
