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 the differential diagnosis of spinal metastases by low field strength MRI and analyze the MRI signs to improve the early diagnosis of spinal metastases. Methods Fifty patients with spinal metastases were examined by MRI and MRI findings of spinal metastases were observed. Summarize the difference of their image performance. Results 50 cases, involving a total of 146 vertebral body. A single vertebra in 12 cases, multiple vertebral 38 cases. 108 anterior and posterior edge of vertebral kyphosis. 29 cases of vertebral compression fractures, 22 cases of soft tissue mass, soft tissue mass often destroy the area as the center of growth. 146 lesions in the vertebral body, 108 vertebral anterior and posterior border protrusion. 29 cases of vertebral compression fractures, 22 cases of soft tissue mass, soft tissue mass often destroy the area as the center of growth. Conclusion MRI examination is more sensitive and specific in the differential diagnosis of spinal metastases and other spondylopathy. Combined with clinical data, MRI can be distinguished from other diseases.
