因此,椎间盘退变是脊柱疾病的重要表象。 磁共振成像 (MRI) 上的 T2 加权像通常用于确定椎间盘退变程度的定性[4,5]。在MRI中评估腰椎间盘退变最常用的方法是Pfirrmann分级[6] ,该方法是一种简单实用的利用椎间盘信号强度和椎间高度分为5级的定性评估方法。...

TE=111 ms，矩阵=256×256。MRI 检查结果见图1，图2。图1为脊柱T2加权像矢状面，该图可见T10-T11椎间盘T2WI 信号减低，向背侧隆起，挤压脊髓（箭头），提示椎间盘脱水、钙化变性，受压脊髓表现弥散T2高信号。图2为T10~T11的T2WI 横断面，可见椎间盘低信号，向背侧膨出，脊髓腹侧受压变形，呈高信号。
腰椎不稳时,在站立位时(X线片)椎体向前滑移,小关节间隙变窄;在仰卧位时(MRI片)椎体复位,造成腰椎小关节的关节间隙增大,关节内T2像高信号,为关节积液。有学者探讨了腰椎不稳和小关节积液量的关系,认为具有相关性,也就是说关节积液对腰椎不稳具有较高的提示价值。
