摘　　要：目的:SPECT/CT同机融合显像鉴别诊断骶髂关节区良恶性病变的价值。方法:56例骶髂关节区单发异常放射性分布不能明确诊断行SPECT/CT显像,并通过得到患者的病理诊断或随访6月以上的综合影像诊断。对SPECT图像、CT图像及SPECT/CT融合图像的诊断符合率进行对比,采用SPSS 13.0软件行Mc Nemar检验。结果 :56例患者中,良性病灶41例,恶性病灶15例。SPECT、CT及融合图像对56例病灶的诊断符合率分别为71.4%(40/56)、85.7%(48/56)、94.6%(53/56),SPECT、CT图像分别与融合图像比较,差异均有统计学意义(χ2=28.32和14.27,P均<0.05)。结论 :在对肿瘤患者进行骨显像,发现骶髂关节区病变以良性病变居多,SPECT/CT融合显像可提高诊断符合率。Objective： To evaluate the v alue of SPECT/CT in assessment of sacroiliac joint foci of abnormal bone metabolism classified as indeterminate on bone scanning using99mTc-MDP. Methods： Undiagnosed fifty-six patients with solitary sacroiliac joint abnormal uptake in bone scanning were scanned by SPECT/CT. The final diagnosis was based on patholo-gy or follow-up diagnosis of more than six months. Mc Nemar test was used for data analysis for SPETCT, CT and their fusion images（SPSS version 13.0）. Results： In Fifty-six patients, 15 cases were malignant and 41 cases were benign diseases. The diagnostic accuracy of SPECT, CT and SPECT/CT was 71.4%, 85.7% and 94.6% respectively. The accuracy of SPECT/CT was significantly higher than that of SPECT and CT（χ2=28.32, 14.27, P0.05）. Conclusion： Most of the solitary sacroiliac joint foci caused by benign diseases. SPECT/CT is particularly valuable in the differential diagnosis of benign and malignant sacroiliac joint diseases.
