摘要
目的分析创伤性无骨折脱位型颈髓损伤的MRI表现及其预后的关系。方法回顾性分析21例创伤性无骨折脱位型颈髓损伤的急、慢性期的MRI表现。结果损伤颈髓急性期信号形态变化分3型，慢性期信号形态变化分4型，急、慢性期信号形态的变化有明显的演变关系，并和预后密切相关。结论MRI能明确判断颈髓损伤的程度和范围，显示损伤的病理状态，并能对预后作出预测。
Objective To find the magnetic resonance imaging (MRI) expressions of traumatic cervical spinal cord injuries (TCSCI) without fracture-dislocation (FD) and its correlation with prognosis. Methods Analysed retrospectively MRI of 21 cases with TCSCI without FD in acute or chronic stage. Results According to signal intensity and morphology of injured cervical spinal cord, lesions were divided into 3 types in acute stage and 4 types in chronic stage. A clear changing correlation was observed between acute and chronic stage. Conclusion MRI could identify tile degree and range of cervical spinal cord injuries, reveal the pathological state and predict prognosis.
