脊椎转移瘤的低场强MRI鉴别诊断

The diagnosis and differential diagnosis of the spinal metastasis in low Field MRI

目的探讨脊椎转移瘤的低场强MRI鉴别诊断并分析其MRI征象,以提高脊椎转移瘤的早期诊断率。方法对50例脊椎转移瘤患者进行MRI检查,观察脊椎转移瘤在MRI表现。归纳其影像表现的差异。结果50例中,共累及146节椎体。单个椎体12例,多个椎体38例。108节椎体前后缘隆突。29节椎体压缩性骨折,有软组织肿块22例,软组织肿块常以破坏区为中心生长。146节病变椎体中,108节椎体前后缘隆突。29节椎体压缩性骨折,有软组织肿块22例,软组织肿块常以破坏区为中心生长。结论MRI检查在诊断脊椎转移瘤及与其他脊椎病变的鉴别诊断中更敏感、更具特异性,结合临床资料可以和其他疾病鉴别。

Objective To investigate low field MRI features of metastasis of spine and improve differential diagnosis of the spinal metastasis. Methods The MRI features of 50 cases of the spinal metastasis were analysed retrospectively and concluded the different MR/features. Results MR/ examinations demonstrated that, there were 146 lesions of spinal metastasis in 50 patients, which comprised 12 single and 38 multiple. Con- clusion The low field MRI is sensitivity in detecting the spinal metastasis and helpful in differential diagnosis in spinal metastasis, and which may be distinguished from other diseases in combination with clinical data.
