股骨头软骨下功能不全骨折可能与股骨头坏死相混淆，主要是因为放射学重叠。回顾性分析 7 例软骨下功能不全骨折患者的 Tc-99 m 羟亚甲基二磷酸盐 SPECT/CT 图像，并与 11 例有症状的早期骨坏死患者的图像进行比较。在所有患有软骨下功能不全骨折的髋部中，SPECT/CT 显示股骨头软骨下病变处的摄取增加。另一方面，在所有患有骨坏死的髋部中，在软骨下病变处确认了缺乏摄取。 SPECT/CT 可能有助于区分软骨下功能不全骨折和骨坏死。
Subchondral insufficiency fracture of the femoral head may be confused with osteonecrosis, mainly because of radiological overlap. SPECT/CT with Tc-99 m hydroxymethylene diphosphonate images in 7 patients with subchondral insufficiency fracture were retrospectively reviewed and compared with those from 11 patients with symptomatic early osteonecrosis. In all of the hips with subchondral insufficiency fracture, SPECT/CT showed increased uptake at the subchondral lesions of the femoral head. On the other hand, in all of the hips with osteonecrosis, absence of uptake was confirmed at the subchondral lesions. SPECT/CT may assist in differentiating subchondral insufficiency fracture from osteonecrosis.
