脊柱转移的CT和MRI分析

Analysis of the metastasis in the spine by MRI and CT

目的：探讨脊柱转移的CT及MRI表现。方法：回顾性分析我院2007年10月2009年9月间经临床6个月及以上随访证实或经手术及病理证实的CT和（或）MRI诊断椎体转移瘤54例。结果：溶骨性改变CT 13例,MRI 26例。成骨性改变CT 3例,MRI 4例。溶骨、成骨混合性改变CT 4例,MRI5例。合并骨性椎管受累CT 4例,MRI 6例。合并椎旁软组织肿块CT 2例,MRI 6例。结论：脊柱转移性改变在CT、MRI上均有较典型改变,有助于确定诊断,两者配合可提高诊断率及诊断准确性。

Objective： To analyze the results of MRI and CT for metastasis in the spine.Methods： Clinical data of 54 cases admitted from Oct 2007 to Sep 2009 were analyzed retrospectively,who were with metastasis in the spine and confirmed by surgery,pathological analysis,CT or MRI.Results： CT results showed 13 cases with osteolytic change,3 cases with osteogenetic change,4 cases with mixture change,4 cases complicated with diseases in spinal canal,and 2 cases complicated by mass in para-spinal soft tissue;while MRI results showed 26 cases with osteolytic change,4 cases with osteogenetic change,5 cases with mixture change,6 cases complicated with diseases in spinal canal,and 6 cases complicated by mass in para-spinal soft tissue.Conclusions： Results of both CT and MRI reveal typical changes.The combination application of CT and MRI can elevate the diagnosis rate and accuracy.
