Magnetic resonance imaging (MRI) was used to examine the lumbosacral spine of 27 dogs with degenerative lumbosacral stenosis. Four normal dogs were also similarly imaged. Compression of the soft-tissue structures within the vertebral canal at the lumbosacral space was assessed in two ways: by measuring dorsoventral diameter on T1-weighted sagittal images and cross-sectional area on transverse images. The severity of the clinical signs was compared to the severity of cauda equina compression. No significant correlation was found. It is concluded that degree of compression as determined by MRI at time of presentation is independent of disease severity.
采用磁共振成像（MRI）对27只患有退行性腰骶部椎管狭窄的犬的腰骶椎进行检查。另外对4只正常犬也进行了类似的成像检查。通过两种方式评估腰骶间隙椎管内软组织结构的受压情况：在T1加权矢状位图像上测量背腹径，在横断位图像上测量横截面积。将临床症状的严重程度与马尾神经受压的严重程度进行比较。未发现显著相关性。得出的结论是，就诊时MRI所确定的受压程度与疾病严重程度无关。
