The early diagnosis of aseptic osteonecrosis of the femoral head has always been difficult. By studying 58 cases, the authors have demonstrated the diagnostic superiority of magnetic resonance imaging. As in the literature, we found aseptic osteonecrosis of the femoral head with no clinical sign, neither radiographic nor scintigraphic, by positive magnetic, resonance imaging. Moreover, it enables the simultaneous study of both hips. It gives with precision the age and extent of the necrosed fragment and enables an absolute differential diagnosis with hip algodystrophy. Magnetic resonance imaging is therefore the second and only examination to be carried out after the standard radiography. The couple, radiography and magnetic resonance imaging, gives all the necessary information for the diagnosis and classification of the aseptic osteonecrosis of the femoral head and Te 99m bone scintigraphy and scanner, whose value was limited, can thus be avoided.
股骨头无菌性坏死的早期诊断一直很困难。通过对58例病例的研究，作者证明了磁共振成像的诊断优势。正如文献中所述，我们发现通过磁共振成像呈阳性，存在无临床症状、X线及闪烁扫描均无表现的股骨头无菌性坏死。此外，它能够同时对双侧髋关节进行检查。它能精确给出坏死碎片的年代和范围，并能与髋关节营养障碍进行绝对鉴别诊断。因此，磁共振成像为标准X线摄影之后应进行的第二项也是唯一一项检查。X线摄影与磁共振成像相结合，可为股骨头无菌性坏死的诊断和分类提供所有必要信息，从而可以避免价值有限的锝99m骨闪烁扫描和扫描仪检查。
