摘　　要：目的探讨腰椎间盘病的类型与相邻椎体MRI加权图像上信号改变之间的关系。方法整群选取并回顾分析2012年7月—2014年2月在该院行椎间盘切除术的168例患者资料术前均有MRI、T1加权、T2加权的影像学检查结果,对比分析行手术的椎间盘及上下相邻椎体与正常椎间盘的MRI T1加权、T2加权影像信号的变化强度,记录信号改变的强度,采用统计分析的方法进行对比分析。结果根据MRI加权信号的改变(低或高的信号改变)评估椎间盘病的类型,其信号改变较为明显的是上部相邻椎体的T2加权图像(45.3%);而椎间盘突出的患者信号改变较差(30.9%),结果表明差异具有统计学意义(P<0.05)。结论椎间盘脱出的上部相邻椎体在MRI T1加权像上信号改变明显,在MRI T2加权图像上,椎间盘脱出的上部相邻椎体的信号改变比椎间盘突出者更加明显。Objective To explore the relationship between lumbar disc disease types and adjacent vertebral body on MRI weighted images signal change. Methods Group selection and retrospective analysis of July 2012 - February 2014 before surgery in our hospital of 168 patient data discectomy have MRI, Tl-weighted, T2-weighted imaging findings. Signal inten- sity of the upper and the lower adjacent vertebra and the operated herniated disc were compared with the normal discs, both in Tl-weighted and T2-weighted. Changes in signal intensity were recorded in qualitative variables. Statistical analysis was then performed between two groups. Results Evaluating the type of diseopathy with the presence of signal changes （hypo or hyper signal changes） demonstrated more signal changes in upper adjacent vertebrae in T2-weighted MRI （45.3%）. Howev- er, patients with protruded discs showed less changes （30.9%）. It showed that the difference was statistically significant （P〈 0.05）. Conclusion Extruded discs are associated with increased signal in Tl-weighted MRI （short TR/TE） in the upper ad- jacent vertebrae. Signal changes in T2-weighted MRI （long TR/TE） in upper adjacent vertebrae are significantly more com- mon in extruded discs, in comparison with protruded discs.
