Abstract

Objective To investigate the value of MRI in the early diagnosis of avascular necrosis of the femoral head. Methods Plain film and MRI examinations of 32 femoral heads of 20 cases were performed. CT were performed in 11 cases. Diagnostic results of three modalitis were compaired. Results In the 32 avascular necrosis of the femoral heads of the 20 cases,MR detected all of them (100%); X ray film detected 23 of them (71.9%);CT detected 14 of 19 avascular necrosis of the femoral heads in 11 cases (73.7%). Different specific signs were shown in MR imagings in each groups. Conclusion MRI is the most sensitive modality in the early diagnosis of avascular necrosis of the femoral head. [
