Spontaneous osteonecrosis of the femoral condyle in 40 knees was followed by sequential radiographs and three-phase bone scans using 99mTc-methylene diphosphonate. The characteristic bone scan appearance of focal increased uptake by the medial femoral condyle in blood flow, blood pool, and delayed images helped to make the specific diagnosis in 11 knees that had no characteristic radiographic findings at the time of presentation. The three phases of the bone scan demonstrated a pattern that was useful in determining the activity of the process. There was a gradual loss of hyperemia as healing progressed. Late bone scans were normal or showed nonspecific findings. Radionuclide bone scans were able to confirm or exclude this disease and were superior to radiographs in demonstrating the disease in the acute phase.
对40个膝关节的股骨髁自发性骨坏死进行了系列X线片检查，并使用99mTc-亚甲基二膦酸盐进行三相骨扫描。在血流、血池和延迟图像上，股骨内侧髁局灶性摄取增加的特征性骨扫描表现有助于对11个在就诊时无特征性X线表现的膝关节做出明确诊断。骨扫描的三个阶段显示出一种有助于确定病变活动情况的模式。随着愈合进展，充血逐渐消失。后期骨扫描结果正常或显示非特异性表现。放射性核素骨扫描能够确诊或排除该病，在急性期显示该病方面优于X线片。
