磁共振在平山病诊断中的应用

摘要

目的：探讨平山病患者发病特点、颈椎磁共振扫描方法及诊断价值。方法回顾性分析41例平山病患者，观察平山病患者颈部脊髓改变特点及发生节段，测量脊髓变细程度，分析颈椎磁共振过屈位扫描在平山病诊断中的作用。结果41例患者颈椎磁共振过屈位与直立位扫描比较，颈部脊髓均有变细；平山病过屈位及直立位脊髓前后径比约为92．67％；平山病脊髓最细处与本身颈3椎体水平脊髓比值为76．74％。结论磁共振对平山病诊断具有一定作用，尤其是过屈位扫描对诊断具有重要意义。%Objective To study the hirayama disease onset characteristics , cervical vertebra method and diagnostic value of MRI scans.Methods A retrospective analysis of 41 cases of hirayama disease was done .Cervical spinal cord changes of hirayama disease characteristics and segmental were observed , and degree of spinal cord attenuate was measured .And analysis of cervical spine MRI bends in the diagnosis of hirayama disease was done .Results Through comparing with 41 patients with diagnosis of cervical flexion , upright posi-tion and magnetic resonance ( NMR) , it is found that cervical spinal cord all change is fine .A longitudinal hirayama disease after spinal flexion and the upright position before and after the diameter ratio is about 92.67%.the most even and C3 spinal cord itself ratio of hiraya-ma disease spinal cord is 76.74%.Conclusion MRI in hirayama disease diagnosis has a certain effect , and especially it has important value to the diagnosis.
