目的：对比分析胸主动脉供血与腹主动脉供血肺隔离症的影像学征象。方法：回顾性分析经术后病理证实的23例肺隔离症病例，对比分析胸主动脉供血及腹主动脉供血肺隔离症的CT 图像。结果：23例肺隔离症中，16例由胸主动脉供血，其中7例有2支供血动脉；7例由腹主动脉供血。21例表现为实性软组织密度，1例胸主动脉供血者表现为囊实性不均匀密度，1例胸主动脉供血者表现为局部粗大血管。胸主动脉供血动脉直径（4．8±2．2）mm，长度（37±12）mm，腹主动脉供血动脉直径（3．3±0．5）mm，长度（104±42）mm。胸主动脉供血血管长度及隔离肺组织体积均小于腹主动脉供血（P均＜0．001）。结论：胸主动脉供血及腹主动脉供血肺隔离症的肺内表现相似，胸主动脉与腹主动脉供血动脉长度及隔离肺组织体积存在差异。

Objective:To compare and analyze the imaging features of pulmonary sequestration (PS)supplied by tho-racic aorta and supplied by abdominal aorta.Methods:A retrospective analysis was performed in 23 patients with PS con-firmed by pathology after operation and the CT images were comparatively analyzed according to the source of blood sup-ply.Results:Of the 23 patients with PS,16 cases were supplied by thoracic aorta and 7 of them had two supplying arteries, 7 cases were supplied by abdominal aorta.The lesions appeared as mass with soft tissue density in 21 cases.One case sup-plied by thoracic aorta showed cystic heterogeneous density.In one case supplied by thoracic aorta,focal thick vessel was shown.The average diameter and length of the supplying arteries from thoracic aorta were (4.8±2.2)mm and (37±12) mm respectively,while these from abdominal aorta were (3.3±0.5)mm and (104±42)mm respectively.The length of sup-plying arteries and volume of sequestrated lung tissues supplied by thoracic aorta were smaller than those supplied by ab-dominal aorta (P<0.001).Conclusion:PS supplied by thoracic and abdominal aorta share similar imaging features.The length of supplying arteries and the volume of sequestrated lung tissues supplied by thoracic aorta are different from those supplied by abdominal aorta.
