摘要
目的提高术后椎间盘炎的MRI诊断水平。方法回顾性分析7例临床和手术病理证实术后椎间盘炎的低场MRI表现。结果①病变椎间盘及相邻椎体呈长T1长T2信号7例;②椎间盘破坏致椎间隙变窄7例,T1加权像呈低信号5例,等信号2例,T2加权像呈高信号5例,低信号2例,T2加权像髓核内低信号裂隙消失5例;③相邻椎体终板及终板下骨质破坏;④椎体旁及椎管内硬膜外脓肿5例;⑤Gd-DTPA增强扫描,4例病变椎间盘和相邻椎体信号强度增高。结论低场MRI对术后椎间盘炎的诊断非常有用,而且还能显示硬膜外脓肿或蛛网膜炎等并发症。
Objective To improve the MRI diagnosis of Postoperative discitis.Methods The MRI findings were studied retrospectively in 7 cases with discitis proven by pathology and clinic.Results ①The Intervertebral discs and adjacent vertebral bodies had long T1 and T2 signal intensity in 7 cases. ②The Intervertebral disc was destroyed and narrowed with hypointersity in 5 cases,isointensiey 2 cases on T2WI.The nucleus pulposus hypointensity cleft was disappeared on T2WI in 5 cases. ③The adjacent vertebral body endplate and under the endplate bone were destroyed. ④There were the paraspinal abscess and epidural abscess in 5 cases. ⑤The signal intensity of The signal intensity of The discs and the adjacent vertebral bodies were increased obviously enhanced after Gd-DTPA enhancement in all 4 cases. Conclusion The Low field MRI is avery useful procedure to diagnose the postoperative discitis and can demonstrate the complications such as epidural abscess or arachnoiditis.
