核磁共振与螺旋CT在脊柱外伤诊断中的应用价值对比

Application of Nuclear Magnetic Resonance and Spiral CT in the Diagnosis of Spinal Trauma

目的:对比核磁共振(MRI)与螺旋CT在脊柱外伤诊断中的应用价值。方法:选取在我院就诊的脊柱外伤患者50例,均行MRI和螺旋CT检查,比较两种方式诊断脊柱外伤的效果。结果:CT检出脊椎骨折、神经根损伤、椎体容积改变及椎旁软组织损伤检出情况与MRI诊断比较,差异无统计学意义(P>0.05);MRI检出前纵韧带损伤、后纵韧带损伤及骨挫伤情况明显高于CT检查,碎骨片检出较低,差异有统计学意义(P<0.05)。结论:MRI和螺旋CT诊断脊柱外伤均有一定的应用价值,其中CT检查可准确显示碎骨片移位情况,MRI可清楚显示韧带损伤及骨挫伤等情况。

Objective To compare the value of magnetic resonance imaging(MRI) and spiral CT in the diagnosis of spinal trauma.Methods Fifty patients with spine trauma were selected and examined by MRI and spiral CT.The effects of two methods on spinal trauma were compared.Results There were no significant differences in the detection of vertebral fracture, nerve root injury,vertebral volume change and paravertebral soft tissue injury between the two groups(P>0.05).MRI examination of the anterior longitudinal ligament injury,posterior longitudinal ligament Injury and bone contusion were significantly higher than CT examination,broken bone pieces were lower,the difference was statistically significant(P<0.05).Conclusion MRI and spiral CT have a certain value in the diagnosis of spine trauma.CT examination can accurately show the displacement of bone fragments.MRI can clearly show ligament injury and bone contusion.
