MRI观察脑梗死继发皮质脊髓束华勒变性的变化规律

Effect of MRI on the Changes of Waller’s Denaturation in the Secondary Cortical Spinal Cord of Cerebral Infarction

目的:探讨MRI观察脑梗死继发皮质脊髓束华勒变性的变化规律。方法:收集2017年1月~2018年3月本院放射科进行MRI检查的患者,分为CST高信号组和CST等信号组。对比两组在发病不同时间后MRI T1WI轴位图像中大脑脚宽度比的变化及NIHSS评分。结果:CST高信号组在发病后6个月及及发病后12个月的大脑脚宽度比明显低于对照组,两组结果比较有差异(P<0.05);CST高信号组及CST等信号组在入院时及发病后1个月的NIHSS评分结果比较无差异(P>0.05);CST高信号组在发病后6个月及发病后12个月的NIHSS评分明显高于对照组,两组结果比较有差异(P<0.05)。结论:MRI观察脑梗死继发皮质脊髓束华勒变性的变化规律,可以推测患者预后情况,当大脑脚宽度比越高时,提示脑功能恢复越差。

Objective:To investigate the changes of cortical spinal cord fasciculus Waller degeneration secondary to cerebral infarction by MRI.Methods:The patients who underwent MRI in radiology department of our hospital from January 2017 to March 2018 were collected,and divided into CST high signal group and CST signal group.Compared with the changes of cerebral foot width ratio and NIHSS score in MRI T1WI axial images at different time points between two group.Results:CST high signal group’s ratio of cerebral foot width to foot width in 6 months after onset and 12 months after onset was significantly lower than control group,and there was no significant difference in the NIHSS score between the two groups at admission and 1 month after onset(P>0.05);CST high signal group’s NIHSS score was significantly higher than control group at 6 months after onset and 12 months after onset(P<0.05).Conclusion:MRI can predict the prognosis of the patients by observing the changes of the cortical spinal cord fascicle Waller degeneration secondary to cerebral infarction.The higher the ratio of the width of the cerebral foot to the foot,the worse the recovery of brain function.
