Traumatic Spinal Cord Injury: A Comparison between MRI Findings and Clinical Manifestations

目的 评价MRI在脊髓损伤的临床应用价值。资料与方法 回顾性分析 6 6例脊髓损伤的临床及MRI表现 ,着重分析脊髓损伤的MRI征象与病理、临床的关系。结果 MRI显示椎体压缩性骨折 5 1例 ,椎间盘脱出 2例 ,椎体骨折并椎间盘脱出 5例 ;椎体部分性滑脱 2 0例 ,完全性滑脱 1例。显示脊髓完全性截断 4例 ,部分性截断 1例 ,脊髓受压 4 1例。 6 2例脊髓连贯者 5 9例显示脊髓信号异常。 5 9例有完整的住院治疗记录 ,治疗后显示病情好转 2 5例 ,症状无改善 2 6例 ,死亡 8例。结论 MRI检查能明确脊髓有无损伤以及损伤的程度 。

Objective To assess the clinical application of MRI in spinal cord injury.Materials and Methods Clinical data and MRI findings in 66 patients with spinal cord injury were retrospectively analyzed, focusing on the relation between MRI signs, pathological results and clinical manifestations.Results MRI showed vertebral fracture in 51, intervertebral disc extrusion in 2 and vertebral fracture with disc extrusion in 5 cases. Besides, partial and complete vertebral olisthy was seen in 20 and one case, respectively. Partial and complete fragmentation of the spinal cord was demonstrated in 4 and one case, respectively. In 41 cases the spinal cord was compressed due to the fracture, subluxation or disc extrusion. Of 62 patients with coherent spinal cord, abnormal signal in the injured area was demonstrated in 59, of which clinical improvement after treatment was seen in 25, no improvement in 26 and death occurred in 8.Conclusion MRI can clarify the presence or absence of the spinal cord injury and determine the extent of the injury, very helpful for guiding clinical management and evaluating the prognosis.
