Introduction

MRI is the established gold standard for imaging acute spinal cord injury (SCI). Our aim was to identify the prognostic value, in terms of neurological outcome, of extradural and intradural features detected on MRI performed acutely following traumatic cervical SCI.

Materials and methods

Several databases were systematically searched to identify potentially eligible articles until December 2019. Using a standard PRISMA template, 2606 articles were initially identified.

Results

A final 6 full-text articles met the inclusion criteria and were analyzed. An extradural factor, namely the maximal spinal cord compression, was associated with poor neurological outcome and statistically significant (P = 0.02 and P = 0.001 in 2 out of 3 studies). The intradural factors of length of the cord edema (P = 0.001, P = 0.006, and P < 0.001 in 3 studies), intramedullary hemorrhage (P = 0.002, P < 0.001, P < 0.001, and P = 0.002 in 4 studies), and the length of intramedullary hemorrhage (P = 0.028, P = 0.022 in 2 studies) also significantly correlated with poor neurological recovery at follow-up.

Conclusion

While early MRI is established as a gold standard imaging of acute spinal trauma, it also serves to provide prognostic value on the neurological recovery. From our systematic review, there is a strong association of the extradural finding of maximal spinal cord compression, intradural MRI findings of length of cord edema, intramedullary hemorrhage, and length of intramedullary hemorrhage with neurological recovery in traumatic cervical spinal cord injuries.

MRI检查结果可以预测颈脊髓损伤的预后吗？系统的审查。

介绍

MRI是对急性脊髓损伤（SCI）进行成像的公认金标准。我们的目的是根据神经学结果确定在创伤性宫颈脊髓损伤后急性进行的MRI所检测到的硬膜外和硬膜内特征的预后价值。

材料和方法

直到2019年12月，系统地搜索了几个数据库以识别可能符合条件的文章。使用标准PRISMA模板，最初识别了2606篇文章。

结果

最后的6篇全文文章符合纳入标准并进行了分析。硬膜外因素，即最大脊髓压迫，与神经系统预后不良相关，且具有统计学意义（ 3项研究中有2项P  = 0.02和P = 0.001）。硬膜水肿长度的硬脑膜内因素（ 在3个研究中P  = 0.001，P = 0.006和P <0.001），髓内出血（在4个研究中P  = 0.002，P  <0.001，P  <0.001和P  = 0.002） ，以及髓内出血的时间（P  = 0.028，P 在2项研究中= 0.022）也与随访时神经功能恢复差相关。

结论

早期MRI被确立为急性脊柱外伤的金标准成像，但它也可为神经恢复提供预后价值。从我们的系统回顾，有最大的脊髓压迫的硬膜外发现的强相关性，在外伤性颈脊髓损伤神经功能恢复脊髓水肿，出血髓内和髓内出血的长度的长度的硬膜内MRI表现。
