To determine whether a visually apparent increase in the antero-posterior diameter of the spinal canal can be used reliably to differentiate degenerative from isthamic spondylolisthesis on midline sagittal MR images. It is hypothesized that the wide canal sign would be present only in isthmic spondylolisthesis, where the vertebral ring is disrupted by defects in the pars interarticularis and absent in degenerative spondylolysthesis where there is no such defect.
