无骨折脱位颈段脊髓损伤的MRI表现

目的：探讨无骨折脱闰颈段脊髓损伤的机制及ＭＲＩ表现。方法：收集１５例经Ｘ线，ＣＴ或ＭＲＩ检查未见骨折脱位的颈段脊髓损伤的病例。所有病例均行矢状位，轴位扫描，均行ＳＥ序列Ｔ１ＷＩ及ＦＳＥ序列Ｔ２ＷＩ。结果：７例有颈椎间盘突出，其中４０岁以上的有６例，前纵韧带撕裂５例，４例为４０岁以上，脊髓受压７例，为突出间盘及肥厚黄韧带压迫所致。所有病例在Ｔ２ＷＩ均呈现出明显的异常信号。脊髓挫伤，水肿１１例，出血１

MRI findings of cervical spinal cord injury without fracture and dislocation

Objective: To investigate the mechanism of cervical spinal coal in injury without fracture and dislocation and to demonstrate the WRI fiedingr of the inilny. Methods: fifteen patiens with eervical spinal cord injury with the boare and dialca1ion were studied with 1.5T magn. ha: Intervertebral disk hewhation was seen with Mm in seven peients. sit of theIn were over 40 yeare old.Anterior longitudinal ligament was ruptured in five cases, four of them were over fourty. Spnal cord was comprssed by driated disk in four cases. Abn0rmal signal on T2WI was seen in all cases. spind coul contusion and edema were seen in eleven cases. Hemorrhage was seen in two cases,and cyst in two also. Conclusions: The spnal cord injdries hauly occur hy means of eithe one of the two mechanisms: forent contusion, or compession of the sPinal coal by the hewhated disk. The area of the spinal cord injmp in children is more extensive than in adult, and there is usuall no compresson on the spinal cord which is usually seen in adults. MRI is the best all to diagnose the spinal cord injury.
