[ Initial nuclear magnetic resonance tomography results of the treatment course of avascular femur head necrosis after femoral core decompression ] . The vascular femoral head necrosis is a serious illness , especially when appearing in patients aged 30 to 50 years . Many etiologic factors cause a femoral head necrosis such as , for example , high-dose steroids , abuse of alcohol , defect of bone marrow and trauma of the hip . Often the X-ray photograph leads to the diagnosis in the second stage ( ARCO 1992 ) or in the third stage , when the femoral head has begun to collapse . The stage IIc and III shows an evident enhancement in contrast media in MRI . Contrast enhancement is demonstrated by STIR , FATSAT , T1-weighted and dynamic screening sequence . The characteristics of the contrast media enhancement argue for an active concomitant process of destruction and regeneration . This stage has the best chances for a drug or a surgical therapy . The evaluation of the signal intensity by the dynamic screening sequence is considered as an objective contribution for the staging of the femoral head necrosis . This enables one to differentiate between the curable stage IIc and the stage III , showing the beginning of breakdown of the femoral head .
