【摘要】 目的比较计算机断层扫描(CT)、磁共振(MR)对腰椎间盘突出症的诊断价值。方法对120例疑似腰椎间盘突出症患者实施CT、MR检查,以手术病理诊断结果为金标准,比较CT、MR的诊断价值。结果 MR对腰椎间盘突出症的诊断灵敏度、特异度、准确度、阳性预测值及阴性预测值均高于CT(P<0.05)。MR对脊髓变性、神经根受压的检出率均高于CT,而CT对钙化、椎间盘积气的检出率均高于MR(P<0.05)。结论 MR对腰椎间盘突出症的诊断准确性优于CT,但对钙化、椎间盘积气等征象的检出率不及CT。更多还原

【Abstract】 Objective To compare the values of computed tomography(CT) and magnetic resonance(MR) in the diagnosis of lumbar disc herniation. Methods A total of 120 patients with suspected lumbar disc herniation were examined by CT and MR, and the diagnostic values of CT and MR were compared with the gold standard of surgical pathological diagnosis. Results The diagnostic sensitivity, specificity, accuracy, positive predictive value and negative predictive value of MR for lumbar disc herniation were higher than those of CT(P<0.05). The detection rates of spinal cord degeneration and nerve root compression by MR were higher than those by CT, while the detection rates of calcification and intervertebral disc pneumatosis by CT were higher than those by MR(P<0.05). Conclusion The diagnostic accuracy of MR is better than that of CT in the diagnosis of lumbar disc herniation, but the detection rates of calcification and intervertebral disc pneumatosis are lower than those of CT.更多还原
