目的探究分析CT与MRI两种影像 学检查方法在诊断极外侧型腰椎间盘突出 症价值及各自的特点。方法 病例来源于 我院骨科2010年1月-2014年4月收治的确 诊为极外侧型腰椎间盘突出症病患66例， 分别使用CT与MRI对其进行检查，观察比 较两种影像学方法检出阳性率及其各自的 影像学特点。结果 分别比较两种检查方 法对各节段椎间盘突出与突出程度的检出 率及总的检出率，差异均不明显，不存在 统计学意义(P>0.05)。结论 CT和MRI影像 学检查对极外侧型腰椎间盘突出症均能诊 断准确，能够较好的判断极外侧型腰椎间 盘突出症病患的程度与节段，具有较重要 的临床诊断价值。

Objective To explore the imaging examination diagnosis value and analysis the characteristics of the two methods: CT and MRI on the extreme lateral lumbar intervertebral disc protrusion. Methods 66 cases were diagnosed with the extreme lateral lumbar intervertebral disc protrusion disease, from our hospital orthopedic from January 2010 to April 2010. Respectively using CT and MRI to check, compare two methods of imaging detection positive rate and their imaging characteristics. Results To compare two methods of inspection of each segment disc herniation with prominence detection rate and the total detection rate, differences are not obvious, there is not statistical significant (P>0.05). Conclusion The CT and MRI imaging examination can diagnose type of extreme lateral lumbar intervertebral disc protrusion, to better determine the degree of type extreme lateral lumbar disc disease patients with segmental, has the important clinical diagnostic value.
