摘要
目的 :总结术后腰椎间盘炎的MRI表现 ,以提高对本病的认识。方法 :对 15例经病理和临床证实的术后腰椎间盘炎就MRI表现进行了回顾性分析。结果 :MRI表现包括 :(1)椎间隙变窄 ,以及邻近的椎体骨髓信号呈长T1长T2 信号 ;(2 )T2 WI上髓核内低信号裂隙消失 ;(3)椎旁软组织肿胀 ;(4)MR增强后受累椎间隙和邻近椎体的信号明显增强。结论 :MRI能全面评价术后腰椎间盘炎 ,对其诊断有重要价值。
Objective To summarize the MRI manifestations of the postoperative lumbar diskitis and to improve the recognization of this disease. Methods Fifteen cases of the postoperative lumbar diskitis underwent MRI scan, and the MRI findings were reviewed. Result MRI manifestations include: (1)the intervertibral disk space narrowed, and the bone marrow adjacent to the involved disk space showed long T 1 and T 2 signal intensity. (2) the intranuclear cleft disappeared on T 2 WI. (3) paraspinal soft tissue swelled. (4) the signal intensity in the sick spaces and adjacent vertibral bodies increased obviously after Gd-DTPA administration. Conclusion MRI can evaluate completely the postoperative lumbar diskitis, and has high value to dignose this disease.
