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 sagittal 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.
