胸椎创伤的磁共振诊断价值

Diagnostic value of MRI in trauma of thoracic vertebra

目的 :研究胸椎创伤的磁共振表现及诊断价值。方法 :回顾性分析 30例胸椎损伤病人的 4 1幅 MRI图像。 19例为急性损伤 ,11例为慢性损伤。结果 :19例急性损伤的 MRI显示 :髓外软组织改变9例 ,占 4 7% ;髓内改变 13例 ,占 6 8% (包括挫伤和硬膜外血肿 ) ;11例慢性期 MRI片 ,89%发现髓内异常 ,包括脊髓压迫、萎缩、软化或空洞。结论 :MRI对胸椎急性损伤可用来辨别造成髓内异常的原因和显示髓外软组织的异常 ;对慢性期创伤 。

Objective: To study the diagnostic value of MRI in trauma of thoracic vertebra and spinal cord, methods: A retrospective analvsis of 41 MRI examinations in 30 patients with previous thoracic vertebra and cord trauma was carried out. Among These 19 were acute injuries, 11 were chronic Results: 19 acute injuries showed 9(47%)extraspinal soft tissue changes and 13(68%) intraspinal lesions (mostly were spinal cord contusion and extradural hematoma);11 chronic injuries showed intraspinal abnormalities in 89%, including spinal cord compression, atrophy, myelomalacia and syringohydromyelia Conclusion: MRI can reveal the etiology of thoracic cord damage in acute injury, the traumatic soft tissue components are particularly well demonstrated with MRI. In the chronic stage, various pathologic changes can be identified accurately and deliver gurilance to surgical therapy Hence, MRI is recommended as a necessary procedure in investigation of thoracic cord injury
