| 摘 要： | 目的：探讨脊柱转移瘤的MRI表现及诊断价值。材料与方法：回顾性分析52例经临床和病理证实的脊柱转移瘤的MRI表现。结果：（1）52例共累及209节椎体,167节附件,“跳跃征”发生率占71．7％。（2）病灶T1WI均表现为低信号,T2WI因其类型不同而分为高（24．4％）,低（30．1％）和混杂（45．5％）信号,“晕征”出现率占26．9％。（3）椎旁肿块、椎管受累和椎间隙狭窄发生率分别为57．1％、60．7％和64．3％。结论：MRI对脊柱转移瘤的诊断有重要的价值。

| Abstract: | Purpose:To explored the MRI signs and diagnostic values of spinal metastases.Materials and Methods:The MRI Features of 52 cases of spinal metastases proved clinically or histologically were analyzed retrospectively.Results:(1)52 cases had destoryed 209 vertebral body and 167 accessory parts.The "Jump Up"sign occurred in 71 7% cases;(2)Tumors generally appeared hypointense on T 1WI.Depending on different bony destructive types,the signals on T 2WI were divided into three groups:high(24 4%),low (30 1%)and mixed (45 5%).The "halo" sign occurred in 26 9%.(3)Masses of paravertebra,intraspinal involvement and accessory intervertebral foramen narrow were 57 1%,60 7% and 64 3%.Conclusion:MRI is great practical important in the diagnosis of spinal metastases. |
