摘　　要：目的探讨多层螺旋CT(MSCT)及磁共振成像(MRI)在胸腰椎爆裂型骨折中的临床应用价值。方法回顾性分析52例胸腰椎爆裂型骨折临床、影像学资料,所有患者均行MSCT及MRI检查,比较两者诊断结果,分析骨折合并脊髓、韧带及椎间盘损伤等情况MSCT、MRI表现。结果 52例中,椎管内骨折片的显示MSCT优于MRI(49个比40个,P<0.05);韧带、脊髓及椎间盘等软组织损伤的显示MRI均优于MSCT,MRI发现韧带损伤15例,MSCT 1例(P<0.01);脊髓损伤CT检出6例,MRI 25例(P<0.01);椎间盘损伤MSCT检出5例,MRI 39例(P<0.01)。结论脊柱损伤应常规行MSCT检查,MRI应作为韧带、脊髓损伤的首选检查。胸腰椎爆裂型骨折尤其存在不稳定骨折者,应同时选用MSCT和MRI检查。Objective To explore the clinical value of multi-slice helical CT（MSCT） and magnetic resonance imaging （MRI） in diagnosis of thoracolumbar burst fractures. Methods The clinical record, MSCT and MRI of 52 thoracolumbar burst fractures were reviewed. Diagnosis of fracture and complications of spine cord, ligament and intervertebral disc injury on MSCT and MRI were retrospectively analyzed. Results Of 52 cases, MSCT （49） was significantly better than MRI （40） for delineating the fracture fragments in the vertebral canal （P〈0.05）. MRI was superior to CT for demonstratingligament （15,1）, spinal cord （25, 6） and intervertebral disk （39, 5） injury （P〈0.01）. Conclusion MSCT is the initial investi- gation for vertebral injury. MRI can be considered for ligament and spinal cord injury. In thoracolumbar burst fractures, both MSCT and MRI should be performed.
