1、腰椎骨质增生与椎间盘膨出或突出的相关性【摘要】目的探讨腰椎骨质增生与椎间盘膨出或突出的相关性，分析骨赘常见MRI信号类型。资料与方法回顾性分析行腰椎MRI检查的202例患者的影像学资料，分别记录腰椎有无骨赘形成、最长骨赘长度及信号、椎间盘膨出或突出程度，并分析所有患者及男性患者、女性患者各自最长骨赘长度与椎间盘膨出或突出程度之间的相关性。结果202例腰椎图像包括1010个椎体，其中156个椎体有肉眼可见骨赘形成，MRI上骨赘主要表现为T1和T2等或高信号，STIR低信号，平均最长骨赘长度为(05.80士2.40~，平均椎间盘膨出或突出程度为(06.17士2.64)~，两者呈显著正相关(r
