Skeletal scintigraphy and QCT were performed to determine changes of subchondral bone tissues in osteoarthritis of the knee and findings were compared with plain X-ray findings, knee pain and femoro-tibial angle. Results on blood pool study were especially related to pain. Results on delayed study using single photon emission computed tomography revealed high uptake on the medial side of the femur and tibia parallel to plain X-rays and pain. The QCT value was slightly decreased as osteoarthritic changes progressed without a significant change. In addition, delayed study in cases with previous surgical intervention by high tibial osteotomy revealed a lower uptake on the medial side of the femur and tibia. When skeletal scintigraphy accurately reflects blood flow through the subchondral bone tissues and is closely related to morbidity and pain, this modality is valuable in analysis of signs and symptoms as well as postoperative outcome.
进行骨骼闪烁扫描和定量计算机断层扫描以确定膝关节骨关节炎中软骨下骨组织的变化，并将结果与普通X线检查结果、膝关节疼痛和股骨-胫骨角度进行比较。血池研究结果与疼痛尤其相关。使用单光子发射计算机断层扫描的延迟研究结果显示，股骨和胫骨内侧的摄取量较高，与普通X线检查结果和疼痛情况相符。随着骨关节炎变化的进展，定量计算机断层扫描值略有下降，但无显著变化。此外，对先前接受高位胫骨截骨术手术干预的病例进行的延迟研究显示，股骨和胫骨内侧的摄取量较低。当骨骼闪烁扫描能够准确反映软骨下骨组织的血流情况，且与发病率和疼痛密切相关时，这种检查方式在分析体征和症状以及术后结果方面具有重要价值。
