颈脊髓损伤MRI的诊断分型(附66例手术所见分析)

本文报告66例急性颈髓损伤,通过MRI检查,有三种压迫颈髓情况:1.单纯椎间盘突出,2.椎间盘与骨折块一起压迫颈髓;3.单独骨折块压迫颈髓。在脊髓成像上显示的病理变化;1.硬脊膜与脊髓水肿,在T_2—wis上为明亮的高信号成像;2.脊髓信号呈暗淡的低信号成像;3.脊髓信号变化的脊段没有脊髓受压现象。在治疗上:单纯椎间盘突出患者效果比较满意,椎间盘与骨折块同时压迫者或单独骨折块压迫者效果比较差;脊髓信号变化与受压平面不一致者,可给予保守治疗,必要时,手术能获得满意效果。

Diagnosis and Classification of MRI for Cervical Spinal Cord Injuries (An Analysis of 66 Cases)

Sixty-six cases of acute cervical cord injuries were reported in this paper. Three types of injuries were described by way of MRI examination:1. Simple disc herniation,2. Disc herniation with bone fragment compression, 3. Simple bone fragment compression. Three features of pathological changes of the cord were demonstrated by MRI:1. Edema of the cord and dura,which showed bright high intensity signal in T2 - wis image, 2.Dark low intensity signal of the cord, 3- Various signals of the cord without phenomenon of compression. The treatment results of simple disc herniation were better than that of the another two types. If the signal changes of the cord does not consistent with the compressive level,conservative therapy should be taken. Surgical treatment,if need be,would achieve good results.
