MRT was performed, using a 0.5 and 1.5 Tesla magnet, on 150 patients with FBSS between three days and 23 years following lumbar disc surgery. T1-weighted spin echo sequences were obtained before and after the application of gadolinium (0.15 mmol/kg). In 67 patients the MRT findings were compared with surgical observations. MRT had a sensitivity of 94% in diagnosing recurrent prolapse, a specificity of 100% and accuracy of 94%. The ventral epidural scar tissue, the disc and the neighbouring vertebral bodies showed increased contrast uptake over a prolonged post-operative period.
使用0.5特斯拉和1.5特斯拉的磁体，对150例腰椎间盘手术后3天至23年出现FBSS的患者进行了磁共振成像（MRT）检查。在注射钆（0.15 mmol/kg）前后获取了T1加权自旋回波序列。对67例患者的MRT检查结果与手术观察结果进行了比较。MRT诊断复发性椎间盘突出的敏感性为94%，特异性为100%，准确性为94%。在术后较长一段时间内，腹侧硬膜外瘢痕组织、椎间盘及相邻椎体的造影剂摄取增加。
