Avascular necrosis of the femoral head: MR imaging with radiological and histological correlation

摘要

Conclusions MR imaging plays an important role in the diagnosis of AVN of femoral head especially in the early detection of AVN. The MR patterns of AVN is not correlated with radiographic stages exactly. Objective To assess the value of MR in the di- agnosis of avascular necrosis (AVN) of the femoral head. Methods MR images in 34 consecutive patients (26 men and 8 women) with AVN (57 hips) were re- viewed. All lesions were confirmed by radiographic, ra- dionuclide, computed tomographic, and/or histologic examination. Eleven specimens were obtained after to- tal replacement of the hip.
