摘　　要：目的:探讨MSCT血管成像在肺隔离症诊断中的应用价值。方法:经临床手术及病理证实的肺隔离症患者23例,均行X线平片、MSCT平扫及CTA检查,结合图像后处理技术(MPR、MIP、VR),分析本病在MSCT检查中的特征性影像学表现。结果:肺隔离症位于左肺下叶16例,右肺下叶7例。表现为肺野内实性肿块者11例;囊性病灶者8例,其中1例为单囊;表现为团片状病灶者3例;表现为单纯主动脉分支与下肺静脉吻合1例。23例隔离肺的供血动脉均发自体动脉,其中19例发自胸主动脉,4例发自腹主动脉。结论:MSCTA各种后处理技术的有机结合可准确、直观地显示隔离肺组织的供血动脉,MSCTA可以作为目前诊断肺隔离症的首选检查方法。Objective：To evaluate MSCT angiography for the diagnosis of pulmonary sequestration.Methods：Twenty-three cases of pulmonary sequestration confirmed by surgery and pathology were examined by X-rays and multi-slice spiral CT with plain and enhanced scanning.All images were reconstructed by post-processing technology（MPR,MIP,VR）,and then characteristic multi-slice spiral CT images were obtained.Results：The lesions were located at the bottom of left lung in 16 cases and at the bottom of right lung in 7 cases.The lesions appeared as solid mass in 11 cases,cystic form in 8,solid in 3 and simple anastomosis of aortic brauch with inferior pulmonary vein in one.23 cases were supplied by the systemic arterial blood,including 19 cases from the thoracic aorta and 4 cases from the abdominal aorta.Conclusion：MSCT angiography technology can accurately and directly display the blood-supply of the segregation tissue.So this method can be used as a preferred method in the diagnosis of pulmonary sequestration.
