The study aimed to identify and characterise changes occurring in the vertebral end-plate on MRI following uncomplicated lumbar discography. MRI was performed immediately before and within 2 h after uncomplicated lumbar discography in 20 consecutive patients undergoing the study as a precursor to possible spinal fusion. Of these, seven patients underwent a further MRI study at a mean of 72 days after discography (range 19-183 days). The MRI scans were assessed for the presence of any changes in the end-plates prior to and following discography. End-plate changes were identified in eight patients (40%) prior to discography. No new changes in end-plate signal intensity (SI) were identified in either the immediate or delayed MRI studies. The study suggests that any changes occurring in the vertebral end-plate following discography should be considered due to infectious discitis. There is no support for the concept of chemical discitis, chemical irritation of bone or microfracture of subchondral trabeculae as a cause of pain at discography.
该研究旨在识别并描述单纯腰椎间盘造影术后MRI上椎体终板发生的变化。对20例连续接受该研究的患者在单纯腰椎间盘造影术前及术后2小时内进行MRI检查，作为可能进行脊柱融合术的前期检查。其中，7例患者在椎间盘造影术后平均72天（范围19 - 183天）进行了进一步的MRI检查。对MRI扫描结果评估椎间盘造影术前及术后终板是否存在任何变化。在椎间盘造影术前，8例患者（40%）发现终板有变化。在即时或延迟MRI研究中均未发现终板信号强度（SI）有新的变化。该研究表明，椎间盘造影术后椎体终板发生的任何变化都应考虑为感染性椎间盘炎所致。没有证据支持化学性椎间盘炎、骨化学性刺激或软骨下小梁微骨折是椎间盘造影时疼痛原因的观点。
