摘　　要：目的:探讨多层螺旋CT三维重建在腹股沟区解剖的应用。方法:回顾性分析20例行多层螺旋CT腹股沟区扫描的三维重建图像,观察在横断面、冠状面及矢状面上腹股沟韧带、腹壁下动脉、圆韧带或精索的显示情况。结果:20例病例中腹壁下动脉在3个轴面上均能显示,显示率100%。横断面不能很好的显示腹股沟韧带,圆韧带或精索的显示率为70%。冠状面能100%显示腹股沟韧带,圆韧带或精索的显示率为77.5%。矢状面腹股沟韧带的显示率为90%,圆韧带或精索的显示率为72.5%。结论:结合多层螺旋CT重建的横断面、冠状面及矢状面图像能满意显示腹股沟区的关键解剖结构,对诊断分型腹股沟疝有较大意义。Objective：To evaluate multi slice spiral CT （MSCT） with three-dimensional reconstruction techniques in the study of the anatomy of inguinal region. Methods： MSCT three-dimensional reconstruction images of inguinal region in order to display the inguinal ligament （IL） ,inferior epigastric artery （IEA） and round ligament or spermatic cord on the ax- ial, coronal, and sagittal views in 20 patients were retrospectively analyzed. Results： The inferior epigastric artery was identi- fied in all planes of all 20 patients （100%）. The inguinal ligament and the round ligament or spermatic cord could only be well identified on axial plane in 70% of 20 patients. On coronal views, the inguinal ligament could be revealed in 100K, whereas the round ligament or spermatic cord could only be showed in 77.5%of the patients. The inguinal ligament was i- dentifiable in 90 % and the round ligament or spermatic cord in 72.5 ~ of the patients on sagittal view. Conclusion： Combi nation of the axial, coronal and sagittal reconstruction images of MSCT could display the key anatomic structures of inguinal region, and is significant in the diagnosis and classification of inguinal hernia.
