MRI在诊断股骨髋臼撞击综合征中的应用

摘要

股骨髋臼撞击综合征(femora acetabular impingement,FAI)被认为是导致髋关节骨性关节炎的重要原因.FAI能够导致关节软骨被破坏.软骨的破坏程度直接影响髋关节骨性关节炎的预后.如果能够早期发现FAI并能及时治疗可以减少髋关节骨性关节炎的发生.如何才能做到早期诊断呢?近来研究表明,MRI是诊断FAI的最好方法.MRI有很高的分辨率和信噪比,能够清晰显示髋关节的软骨及盂唇.文章综述了FAI目前诊断的标准和因难以及高场MRI可能的解决办法.%Femora acetabular impingement (FAI) is thought as the major mason leds to hip osteoarthritis. FAI results to destruction of the arthrodial cartilage. Prognoses of hip osteoarthritis is affected by the degree of arthrodial cartilage destruction.The hip osteoarthritis could be prevented if FAI is diagnosed and treated in earlier period. How can we diagnose FAI in earlier period? Recent studies showed that MRI was the best way for FAI diagnosis. It has higher resolution and signal-noise ratio.Cartilage and gleniod labrum of hip could be shown by MRI. The paper reviewed the standard and difficulties of diagnosis about FAI. High magnet MRI maybe is one way to solve the problems.
