股骨头缺血坏死患者核素骨显像的临床价值

Clinical Value of Bone Imaging for Patients with Avascular Necrosis of the Femoral Head

目的 探讨放射性核素骨显像对股骨头缺血坏死的诊断价值。方法 对 30例股骨头缺血坏死患者行99mTc 亚甲基二膦酸盐 (MDP)骨显像。结果 4 7个缺血坏死的股骨头平面显像呈现“缺损”型、“炸面圈”型和“浓聚”型 ,断层显像为“缺损”型和“炸面圈”型。 13个正常的股骨头中 3个骨显像为“缺损”型。结论 放射性核素骨显像能早期诊断股骨头缺血坏死。

Objective To study the value of radionuclide bone imaging for patients with avascular necrosis of the femoral head.Method 30 patients with avascular necrosis of the femoral head were studied by the radionuclide bone imaging after injection of 99m Tc MDP.Result 47 femoral head of avascular necrosis showed the types of “defect”,“concentrate” and “doughunt”in plane imaging and the“defect” and “doughunt” in tomography.Of 13 normal femoral head,3 femoral head showed the “defect”.Conclusion Radionuclide bone imaging was the diagnostic method for early assessment of the avascular necrosis of the femoral head.
