摘要
目的:探讨MRI对脊髓梗死的诊断价值。方法:选择3岁雄性实验猴,行双侧T12肋间动脉栓塞致脊髓梗死的动物模型,连续动态观察MRI改变。回顾分析了9例患者脊髓梗死的病因,临床特点及MRI表现。结果:实验猴,9例患者MRI矢状位T2WI显示脊髓中央区高信号,轴位T2WI显示脊髓内“H”型高信号及脊髓前角高信号(“猫头鹰”眼征),T1WI在急性期脊髓增粗,慢性期脊髓变细萎缩。结论:MRI是脊髓梗死唯一的首选检查方法。
Objective： To evaluate the diagnostic value of MRI in spinal cord infarction. Methods： Spinal cord infarction was induced in 3-years-old male rhesus through bilateral T12 intercostal artery embolization. The MR imaging features were observed dynamically. Nine patients with spinal cord infarction were retrospectively studied in their etiology, clinical features and MRI changes. Results： The serial MR images in 9 patients and rhesus with spinal cord infarction showed hyperintensity on sag/ttal T2WI located in the center of the spinal cord. On axial T2WI, ＂H＂ shaped gray matter hyperintensity and high signals in the anterior horn of spinal cord （owl＇s eye sign） could be seen. On T1WI, the spinal cord swelled in acute stage and atrophied in chronic stage. Conclusion： MR imaging is the prefered method in diagnosis of spinal cord infarction.
