| 摘 要： | 目的：探讨髋关节撞击综合征的影像学表现.材料与方法：回顾性分析21例髋关节撞击综合征的影像学表现.结果：21例患者共发现28个股骨颈疝窝,病灶均位于股骨头基底和股骨颈前外侧皮质下,形态呈圆形、卵圆形或分叶状.X线平片上表现为伴清晰薄层硬化缘的透亮区,CT上表现为伴锐利的薄层硬化缘的骨质缺损区,MRI T1WI序列表现为低信号,T2WI和STIR为高信号.结论：股骨颈疝窝是髋关节撞击综合征的典型征象,CT和MRI可明确股骨颈疝窝的诊断.

| Abstract: | Purpose： To investigate the imaging features of femoroacetabular Impingement. Materials and Methods： The image findings of 21 patients with femoroacetabular Impingement were retrospectively analyzed. Results： 28 herniation pits of the femoral neck were found in 21 femoroaeetabular Impingement. The lesions were round, X - ray plain film showed a round radiolucency with a thin clear sclerotic rim. CT scans shoued a well - defined lesion. MRI displayed low sig- nal intensity on TI WI and high signal intensity on T2WI and STIR. Conclusion： The CT and MRI findings of herniaton pit of the femoral neck were characteristic, and it, s useful in defining the diagnosis of femoroacetabular Impingement. |
