常规MRI在创伤性脊髓损伤预后评估中的研究进展

Research progress of conventional MRI in prognostic assessment of traumatic spinal cord injuries

创伤性脊髓损伤(TSCI)常由直接的机械性损伤引起,是一种严重的致残性疾病。临床上常借助常规脊髓MRI对脊髓损伤(SCI)严重程度进行评估,所以探讨常规MRI在TSCI中的全面应用进展是非常必要的。MRI可显示TSCI不同时期的变化,急性期MRI能显示脊髓水肿和出血范围,在亚急性期,随着水肿和出血的消退,MRI指标可能对损伤严重程度诊断和预后预测有更大价值;而慢性期MRI能够观察TSCI后脊髓和脑内的萎缩情况。本文回顾近几年相关文献,对TSCI在MRI上的信号表现及MRI对评估神经功能缺损和预测恢复的价值进行阐述,以期为TSCI患者的诊疗和康复及未来研究方向提供建议。

Traumatic spinal cord injury(TSCI)is often caused by direct mechanical injury and is a serious disabling disease.In clinical practice,conventional spinal cord MRI is mostly used to evaluate the severity of spinal cord injuries(SCI),but its comprehensive application in TSCI also deserves exploration.MRI can show the changes in different stages of TSCI.In the acute stage of TSCI,MRI can show the extent of spinal cord edema and bleeding;in the subacute stage,with the subsiding of edema and bleeding,MRI indicators may have greateRvalue foRinjury severity diagnosis and outcome prediction;while in the chronic stage,MRI can reveal the atrophy of the spinal cord and brain.This papeRreviews the relevant literature in recent years,and explains the signal performance of TSCI on MRI and the value of MRI in assessing neurological deficits and predicting recovery following TSCI,to provide suggestions foRthe diagnosis,treatment,rehabilitation,and future research directions of TSCI patients.
