X线、CT和MRI对腰椎间盘突出症诊断的价值对比分析

Comparative analysis of value of X-ray,CT and MRI in the diagnosis of lumbar disc herniation

目的比较腰椎间盘突出症x线、CT、MRI诊断的准确性及临床价值。方法选取2015年1月-2016年3月在本院接受治疗的74例腰椎间盘突出症患者，均接受x线、cT及MRI三种影像学检查。对比分析三种检查方法的诊断价值，总结腰椎间盘突出症的影像表现。结果74例椎间盘突出症患者中，x线、CT、MRI的检出率分别为21．62％、74．32％、87．84％。X线检查的检出率显著低于MRI、CT检查，差异有统计学意义（P〈0．05）。MRI检查的检出率显著高于cT检查，差异有统计学意义（P〈0．05）。结论MRI在腰椎间盘突出症诊断中的准确率优于x线与CT，但扫描时间长、价格高也成为其短板。CT则更加适用于临床，其较x线更加灵敏。当CT检查结果出入较大时，应结合MRI进行诊断，两种检查方法互补以提高检出率。

Objective To compare the diagnostic accuracy and clinical value of X-ray,CT and MRI in lumbar disc her- niation.Methods 74 patients with lumbar disc herniation in our hospital from January 2015 to March 2016 were select- ed and received X-ray,CT and MRI three kinds of imaging examination.The diagnostic value of the three methods were compared and analyzed,and the imaging findings of lumbar disc herniation were summarized.Results In 74 patients with intervertebral disc protrusion,the detection rates of X-ray,MRI and CT was 21.62%,74.32% and 87.84%,respectively. The detection rate of X-ray examination was lower than that of MRI and CT examination,with significant difference （P〈 0.05）.The detection rate of MRI was higher than that of CT,with significant difference （P〈0.05）.Conclusion The accu- rate rate of MRI in the diagnosis of lumbar disc herniation is better than X-ray and CT,but the length of scan time and high price also become the short board.CT is more applicable to clinical,and it is more sensitive than x-ray.When there are large differences in the results of CT examination,which should be combined with MRI to improve the detection rate of complementary.
