摘　　要：目的比较多层螺旋CT(MSCT)与磁共振(MRI)诊断腰椎间盘突出症(LDH)的临床应用价值。方法收集2016年5月-2017年5月就诊的200例LDH患者临床资料展开回顾性分析,患者均经MSCT与MRI检查初步诊断,并经手术病理确诊,以手术病理诊断为金标准,比较MSCT检查与MRI检查诊断LDH的阳性率。比较MSCT检查与MRI检查对LDH征象的诊断情况,包括钙化、椎间盘积气、椎间盘变形、硬膜囊受压、脊髓变形及神经根受压。结果 MSCT检查诊断LDH符合率89.00%(178/200)与MRI检查诊断LDH符合率91.00%(182/200)比较,差异无统计学意义(P>0.05);MSCT检查诊断钙化、椎间盘积气的阳性率显著高于MRI检查,MRI检查诊断椎间盘变形、硬膜囊受压、脊髓变形的阳性率显著高于MSCT检查,差异有统计学意义(P<0.05)。结论在LDH的临床诊断过程中,MSCT与MRI均能取得较好的诊断效能,二者各具优势,其中MRI对椎管内结构的显示效果更好,二者联用可提高诊断准确性。Objective To compare the clinical value between multi-slice spiral CT(MSCT)and magnetic resonance imaging(MRI)in the diagnosis of lumbar disc herniation(LDH).Methods The clinical data of 200 patients with LDH who treated during the period from May 2016 to May 2017 were analyzed retrospectively.All patients were diagnosed by MSCT and MRI,and confirmed by surgery and pathology.With pathological diagnosis as the standard,the positive rates of LDH diagnosed by MSCT and MRI were compared.The diagnosis of LDH signs by MSCT and MRI were also compared,including calcification,intervertebral disc pneumatosis,intervertebral disc deformation,dural sac compression,spinal cord deformation and nerve root compression.Results There was no statistically significant difference in the coincidence rate in diagnosis of LDH between MSCT and MRI[89.00%(178/200 vs 91.00%(182/200)](P>0.05).The positive rates of calcification and intervertebral disc pneumatosis diagnosed by MSCT were significantly higher than those by MRI while positive rates of intervertebral disc deformation,dural sac compression and spinal cord deformation were significantly lower than those by MRI(P<0.05).Conclusion In the clinical diagnosis of LDH,both MSCT and MRI can achieve good diagnostic efficiencies,and both of them have their own advantages.The effect of MRI is better in displaying the internal structure of spinal canal.The combination of the two methods can improve the accuracy of diagnosis.
