We carried out MRI studies of 74 patients with end-plate and vertebral bone-marrow changes associated with degenerative lumbar disc disease. Abnormalities were classified into type A, with decreased signal intensities, and type B, with increased signal intensities on T1-weighted spin-echo images. Twenty-seven (73%) of the 37 patients with type-A changes had low back pain, in contrast to only four (11%) of the 37 patients with type-B changes. Lateral flexion-extension radiographs showed hypermobility in 26 patients (70%) with type-A changes, and in only six (16%) with type-B changes. Type-A changes correlated with segmental hypermobility and low back pain, while type-B changes were more common in patients with stable degenerative disc disease.
我们对74例伴有退行性腰椎间盘疾病的终板和椎体骨髓改变的患者进行了MRI研究。异常情况分为A类，即T1加权自旋回波图像上信号强度降低，以及B类，即信号强度增加。37例A类改变患者中有27例（73%）有腰痛，相比之下，37例B类改变患者中只有4例（11%）有腰痛。侧屈-伸展位X线片显示，26例（70%）A类改变患者有节段性活动过度，而B类改变患者中只有6例（16%）有节段性活动过度。A类改变与节段性活动过度和腰痛相关，而B类改变在稳定的退行性椎间盘疾病患者中更为常见。
