我们将来自骨坏死患者的八个股骨头的术前磁共振 (MR) 图像和组织病理学进行了关联。在纤维血管组织、分解的纤维血管组织或无定形坏死物质占据髓腔的区域，MR 图像的信号强度较低。另一方面，未进行血运重建的坏死骨髓显示出高信号强度。一旦一定量的骨髓被纤维血管组织替代，就可以通过磁共振成像检测到骨坏死。
We correlated preoperative magnetic resonance (MR) images and histopathology of eight femoral heads from patients with osteonecrosis. The signal intensity of the MR image was low in the area where fibrovascular tissue, disintegrated fibrovascular tissue, or amorphous necrotic material occupied the medullary space. On the other hand, the necrotic marrow without revascularization showed high signal intensity. Osteonecrosis can be detected by MR imaging as soon as a certain amount of bone marrow is replaced by fibrovascular tissue.
