【摘要】 目的比较SPECT/CT融合图像和MRI在髋关节良性病变中的诊断价值。方法回顾性分析22例临床疑似股骨头缺血性坏死,并伴有髋部不适、疼痛或活动受限等症状患者的SPECT/CT融合图像和MRI。全部患者核素骨显像和MR检查均于5日内完成,并经临床随访证实。结果22例患者的44个髋关节中,共发现股骨头坏死18髋,关节炎性病变4髋,其中1例患者为强直性脊柱炎。MRI发现股骨头坏死17髋,髋关节炎4髋;SPECT/CT融合图像发现股骨头坏死18髋,髋关节炎4髋,且核素骨显像浓聚或稀疏区与MRI征象之间均存在对应关系。结论SPECT/CT融合图像和MRI两种显像方法在诊断髋关节良性病变中的阳性率相当,两者互为补充,且SPECT/CT融合图像可区分髋臼与股骨头病变,较单纯平面显像提高了诊断的准确率。更多还原

【Abstract】 Objective To compare SPECT/CT fusion imaging and MRI in the diagnosis of benign hip lesions.Methods Twenty-two patients suspected avascular necrosis of femoral head with hip discomfort,pain or action limited were analyzed retrospectively.All patients underwent radionuclide bone scan and MR examination within 5 days,and the diagnosis was proved with clinical follow-up.Results Eighteen necrosis of the femoral head and 4 hip arthritis including 1 patient with ankylosing spondylitis were found in 44 hip joints of 22 patients.MRI detected 17 femoral head necrosis and 4 hip arthritis,while SPECT/CT fusion image found out 18 femoral head necrosis and 4 hip arthritis.There was corresponding relationship in signs of hip lesions between MRI and SPECT/CT fusion imaging.Conclusion SPECT/CT fusion imaging and MRI has no markedly difference in the diagnosis of hip benign lesions,and is complementary to each other.SPECT/CT fusion image can distinguish the hip lesions from the femoral head lesions,and has a higher accuracy of diagnosing hip lesions than whole body bone scanning.更多还原
