MRI全脊柱移床扫描在脊柱损伤的诊断及临床应用

The MRI scan the entire spine moving bed(MobiTrak) of spinal cord injury in the diagnosis and clinical application

目的探讨MRI全脊柱移床扫描(MobiTrak)技术在诊断脊柱、脊髓损伤中的诊断及临床应用价值。方法对48例临床疑有脊柱、脊髓损伤患者行MR全脊柱移床扫描,经后处理完成全脊柱MRI图像;并根据患者体征、临床症状,与以某一椎体为中心的局部脊柱扫描图像进行对比,少数病人行增强扫描。结果 48例患者,损伤部位颈段18例、胸段21例、腰段14例。其中多节段损伤5例。根据MRI表现将其分为单纯压缩骨折无脱位;压缩骨折伴脱位;爆裂性骨折并脱位;无骨折脱位等4类。全部病例均能清楚显示异常的脊髓信号,其中3例可见脊髓断离,1例不全断离。结论 MRI全脊柱移床扫描技术可以很好地反映出脊柱序列、形态、损伤程度和范围;对脊髓损伤的形态、大小和病理改变也能清楚显示;也可对椎间盘、软组织等损伤作出合理判断,是评价脊柱损伤的首选方法之一,对鉴别陈旧性和新鲜骨折有较高的价值。可以有效地指导治疗方法的选择,也有助于预后判断。

Objective To investigate the MRI scan the entire spine moving bed （MobiTrak） in the diagnosis of spinal cord injury in the diagnosis and clinical application. Methods For 48 cases of suspected spinal cord injury patients with spinal-wide shift bed scanning, docking neck, chest, lumbosacral spine images form a complete image of the whole spine. In accordance with the butt before the clinical symptoms and signs to a vertebrae as the center of the local spine scan image contrast, a small number of patients with CT. Results 48 cases of patients, 18 cases of cervical injury site, 21 cases of thoracic, lumbar 14 cases. Of which more than five cases of segmental injury. MRI will be in accordance with the performance of spinal injury is divided into 4 categories： a simple compression fracture without dislocation; compression fracture with dislocation; burst fracture and dislocation; without fracture or dislocation. All patients with spinal cord has been clearly demonstrated abnormal signals, 3 See, for example, breaking away from the spinal cord, which cut off one cases of incompetence. Conclusion MRI scan the entire spine moving bed can reflect patterns of spinal injury and spinal cord injury in the form and pathological changes, but also on the ligament, disc and other soft tissue injury to make an accurate assessment is the evaluation of spinal injury in a good way, can guide treatment choice, will also help determine the prognosis.
