[Application of MR arthrography for diagnosis of femoral acetabular impingement syndrome].

Femora acetabular impingement (FAI) is thought as the major reason 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.
