在 30 例新鲜股骨颈骨折中，将 Tc-99m MDP 显像术中术前股骨头示踪剂的摄取与术中获得的股骨头活检的摄取进行比较，并与同时注射的四环素进行的活体骨染色相关。 Tc-99m MDP 和四环素的骨摄取显示出良好的相关性。股骨头活检中完全缺乏 Tc-99m MDP 摄取，对应的闪烁照相摄取比率为 0.7（对侧头部骨折），而正常的 Tc-99m MDP 活检摄取对应的比率为 1.5。这表明，在正常髋部的 Tc-99m MDP 闪烁检查中，股骨头发射的不到一半来自股骨头本身。
In 30 fresh fractures of the femoral neck, the preoperative femoral-head tracer uptake in Tc-99m MDP scintimetry was compared with the uptake of peroperatively obtained femoral-head biopsies and correlated to intravital bone staining by tetracycline, infused concurrently. Bone uptakes of Tc-99m MDP and tetracycline were shown to correlate well. Total absence of Tc-99m MDP uptake in the femoral-head biopsy corresponded to a scintigraphic uptake ratio of 0.7 (fractured over contralateral head), whereas a normal Tc-99m MDP biopsy uptake corresponded to a ratio of 1.5. This suggests that in Tc-99m MDP scintimetry of a normal hip, less than half of the emission ascribed to the femoral head is derived from the femoral head itself.
