单椎体转移瘤的CT、MRI、SPECT/CT骨显像诊断

The Diagnosis of Metastasis of Tumor to Single Vertebral Body by CT and MRI and SPECT/CT Bone Scan

目的:评价CT、MRI、SPECT/CT骨显像在单椎体转移瘤中的诊断价值。方法:本组单椎体转移瘤66例,所有病例均行CT、MRI、SPECT/CT骨显像检查,并经手术及病理证实。结果:CT阳性率75.76%,MRI阳性率90.90%,SPECT/CT骨显像阳性率100%。CT符合率69.69%,MRI符合率89.39%,SPECT/CT骨显像符合率90.90%。结论:SPECT/CT骨显像可作为筛选临床疑诊椎体转移瘤的首选检查,MRI、CT是其必要的补充手段。

Objective：To appraise the diagnostic value in metastasis of tumor in single vertebral body by CT and MRI and SPECT/CT bone scan.Methods：Sixty-six cases of single body of vertebral metastasis tumor were studied,all cases were examined by CT and MRI and SPECT/CT bone scan,approved by operation and pathology.Results：The positive ratio of CT was 75.76%,and MRI 90.90%,and SPECT/CT 100%.The accurate ratio of CT was 69.69%,MRI 89.39%,and SPECT/CT 90.90%.Conclusion：In the examination of metastasis of vertebral tumor,the SPECT/CT bone scan is the first choice,and MRI and CT could be used as adjuvant methods.
