【摘要】 目的探讨脊柱骨转移瘤的MR去脂序列的影像学特征。方法对70例脊柱转移瘤患者MR图像进行回顾性分析。结果脊柱骨转移瘤的信号改变明显,所有病灶椎体信号均有改变,其中去脂T2W I序列中病灶表现为中等高信号为100%,均高于周围正常椎体信号;脊柱骨转移瘤累及附件、椎旁软组织肿块的形成和邻近椎间盘的无受累对与其他疾病的鉴别诊断具有重要意义。结论MR去脂序列应作为怀疑脊柱骨转移瘤的常规检查手段。更多还原

【Abstract】 Objective To study MR fat suppression imaging features of vertebral metastases.Methods MR imaging features wereretrospectively reviewed in 70 patients with vertebral metastases.MR imaging included T₁WI,T₂WI and fat suppressed imaging.Results The change of signal intensity in the vertebral metastases was obvious.The abnormal signal intensity was revealed in all lesions.Onfat-suppression sequence,all lesions were hyperintensity signal than that of other normal vertebral.The findings including abnormal signal of the pedicle,paravertebral soft tissue masses and no disc destruction were of significant in differentiating metastasis from other disease.Conclusion MR fat-suppression sequence imaging should be used as a routine examination in the cases suspected vertebral metastases.更多还原
