MRI中T2WI高信号长度与急性颈脊髓损伤程度相关性研究

目的：探讨MRI中T2WI高信号长度与急性颈脊髓损伤程度的关系。方法：急性颈脊髓损伤患者37例，其中脊髓完全损伤19例，不完全损伤18例。全部病人均于伤后1～7天行MRI检查，于T2加权矢状位成像上选取高信号最长层面量取其长度，并分析其与颈脊髓损伤程度的关系。结果：急性颈脊髓损伤患者颈髓矢状面T2WI高信号长度，脊髓完全性损伤组明显高于不完全性损伤组（P〈0．01）。结论：MRI是临床诊断急性脊髓损害程度及评估其预后的良好的无创性检测方法。

Study on MRI Characteristics after Cervical Acute Spinal Injury

Objective：To study the correlation between the high signal length on T2WI sagittal plane of MRI and the degree of cervical acute spinal injury. Methods ：Thirty seven cases of cervical acute spinal injury, including 19 cases of complete paralysis and 18 of incomplete paralysis, received inspection by MRI within 1 - 7 days after injuries. To measure the high signal lengths in the damaged areas on T2WI sagittal plane, and analyze the relationship between these lengths and the degree of spinal injury. Results：The patients with complete paralysis had longer signal length in the damaged areas on T2WI sagittal plane of MRI than those with incomplete paralysis. Conclusions： MRI is a favorable and non-invasive examination for evaluating the degree of acute spinal cord injury and predicting prognosis of the patients.
