MRI对髓核游离型腰椎间盘脱出症的诊断价值

目的探讨MRI对髓核游离型腰椎间盘脱出症的诊断价值。方法选择2012年3月～2014年4月本院接诊的30例髓核游离型腰椎间盘脱出症的患者进行研究。术前进行MRI、CT检查。以手术结果作为金标准,比较两种方法的检查准确率。结果 MRI检查游离髓核上移、游离髓核居中、游离髓核下移的准确率均高于CT检查（P〈0.05）;MRI、CT检查的总准确率分别为93.33%、50.00%,两者比较,差异有统计学意义（χ^2=13.8714,P=0.0002）。结论 MRI对诊断髓核游离型腰椎间盘脱出症的准确率高,值得临床推广。

Diagnostic value of MRI on lumbar intervertebral disc prolapse of free nucleus pulposus type

Objective To discuss the diagnostic value of magnetic resonance imaging（MRI） on lumbar intervertebral disc prolapse of free nucleus pulposus type. Methods From March 2012 to April 2014,30 patients with lumbar intervertebral disc prolapse of free nucleus pulposus type visited our hospital were researched. MRI and CT examination were used before surgery,and the surgical results were considered as the golden standard,the test accuracy rate of the two different ways was compared. Results The test accuracy rate of free nucleus pulposus moving upward and downward,and maintaining in the center by MRI was higher than that by CT respectively（P〈0.05）.The total accuracy rate by MRI and CT was 93.33% and 50.00% respectively with a statistical difference（χ^2=13.8714,P=0.0002）. Conclusion The accuracy rate of MRI on lumbar intervertebral disc prolapse of free nucleus pulposus type,and it is worthy of expansion in clinic.
