摘　　要：目的:探讨正常踝关节内、外侧韧带的解剖形态及其MRI和CT表现。方法:6例正常人踝关节新鲜标本MRI扫描,解剖显示内、外侧韧带后,CT断层扫描与MRI对照观察踝关节内、外侧韧带的影像学表现;在30例正常志愿者踝关节的MRI上测量内、外韧带的宽度及厚度。结果:MRI横断面及冠状面可充分显示踝关节内、外侧韧带及其周围组织的解剖结构;踝关节内、外侧韧带在冠状面及横断面上所测的宽、厚度,男女间存在一定的差异。结论:MRI能清晰地显示踝关节的解剖结构,所测量的正常踝关节内、外侧韧带的宽、厚度数据,为临床诊断踝关节内、外侧韧带的病变提供了形态学依据。Objective： To study the anatomy of the lateral and medial ligaments in normal ankle joint and the images of these ligaments on MRI and CT. Methods： MRI displaying of the normal ankle ioints from 6 fresh specimens was followed by dissection of the lateral and medial collateral ligaments. CT scans conducted after the dissection were compared with MRI in this study. The width and thickness of the lateral and medial ligaments were measured on MRI from 30 volunteers. Results： MRI coronal and transverse plane could well display normal anatomy of the ankle joint, including not only the ligaments, but also the important structures around the ligaments. The width and thickness of the ligaments measured on transverse and coronal MRI images were significantly different between male and female. Conclusion： MRI could clearly display the anatomical structures of the ankle joint. The width and the thickness measured through MRI facilitate clinical diagnosis of the ligamentous injury.
