摘要
作者应用电子计算机 X 线体层摄影(CT)和磁共振成像(MRI)对110例腰椎间盘突出症经手术探查的共157个椎间盘的结果进行了分析。其中 CT60例,89个椎间盘,正确率为85.4%,假阳性10个(11.2%),假阴性3个(3.4%)。MRI50例,68个椎间盘,正确率为85.38%,假阳性6个(8.8%),假阴性4个(5.9%)。CT 与 MRI 和椎管碘水造影检查比较,具有无创伤性、放射线量低、对骨骼组织分辨率高和检查费用不高等优点,可作为不典型的腰椎间盘突出症术前诊断和定位的首选方法,MRI 检查和椎管碘水造影术仅在某些特殊情况下施行。如果进一步提高阅片质量和结合临床检查可提高 CT 和 MRI 的正确率。
The operative findings in 110 cases(157 disks)of disk herniation were comparedwith CT or MRI diagnoses.Among the 60 cases having CT examination,herniation wasverified in 76(85.4%)of the 89 disks.In the 50 cases with MRI diagnoses,herniationwas found in 58(85.3%)of the 68 disks.CT and MRI in the diagnosis of lumbar diskherniation are comparable.However,the authors stress the importance of clinical judgementand imaging technics are only complementary.
