目的探析MRI在急性脊柱外伤中的应用。方法选取78例急性脊柱外伤患者,对可疑损伤部位进行CT扫描。在伤后8小时采取T1WI、T2WI横断面,T2WI及脂肪抑制STIR序列矢状面对患者脊柱进行常规MRI扫描,回顾性分析MRI对脊柱损伤的诊断效果。结果 78例患者CT扫描后,结果显示,颈椎椎体骨折且椎管狭窄者有20例患者,腰椎椎体骨折且伴有附件骨折者具有48例患者,胸椎骨折的患者具有6例,骶椎椎体骨折的患者具有4例;78例脊柱骨折中具有88个椎体骨折;脊髓损伤MRI检出率(25/78)32.05%,CT(12/78)15.38%,比较差异有统计学意义(P<0.05);韧带损伤MRI检出率(50/78)64.10%,CT(6/78)7.69%,比较差异有统计学意义(P<0.05)。结论非创伤性脊髓损伤采取MRI检查,效果较好,可以清晰显示脊柱形态、骨折及位置同脊髓的关系等病理改变情况,为临床提供依据。
Objective To explore the application of MRI in acute spinal trauma. Methods A total of 78 patients with acute spinal trauma were selected for CT scan of suspicious lesions. At 8 hours after injury, conventional MRI scan of the spine was performed on the sagittal plane of T1WI, T2WI, T2WI and fat suppression STIR. The diagnostic results of MRI on spinal injury were retrospectively analyzed. Results 78 patients after CT scan, the results showed that 20 patients with cervical vertebral fracture and spinal stenosis, lumbar vertebral fracture with accessory fracture with 48 patients, thoracic fracture patients with 6 cases, sacral There were 4 cases in the vertebral body fractures, 88 vertebral fractures in 78 cases with spinal fractures, 32.05% (25/78) in spinal cord injury and 15.38% in CT (12/78), the difference was statistically significant (P <0.05). The MRI detection rate of ligament injury (50/78) was 64.10%, and CT (6/78) was 7.69%. The difference was statistically significant (P <0.05). Conclusion Noninvasive spinal cord injury using MRI, the effect is better, you can clearly show the spinal morphology, fracture and the relationship between the location and the spinal cord and other pathological changes, provide a basis for clinical.
