摘要
目的:探讨核素显像对股骨头缺血坏死(ANFH)的应用价值。方法:使用大视野γ照相机、针孔准直器,对53例(61侧)股骨头缺血坏死进行血池+静态显像。结果:核素显像诊断ANFH阳性率为90%(55/61侧)。2例无症状及X线表现的患髋的对侧髋显像轻度异常,2年后发展为缺血坏死。结论:采用正确的核素显像方法,不仅能够早期检测ANFH,而且可发现一些亚临床改变,同时可能用于预测股骨头塌陷。
PURPOSE:To evaluate the significance of radioisotope bone scan in patients with Avascular Necrosis of the Femoral Head(ANFH). METHOD:In 61 hips of ANFH, blood pool image were obtained, following 2 hours delayed image with pin hole collimator. RESULT:The sensitivity of imaging is 90%. 2 hips which have no symptoms but with mild abnormal imaging develop ANFH follow for 2 years. CONCLUSION:ANFH can be detected earlier and some subclinical abnormalities and the risk for collapse could be prognosticated.
