Fig. 1From: Evaluation of intervertebral disc degeneration in young adult asymptomatic Dachshunds with magnetic resonance imaging and radiographyModel images of each MRI grade in the two image plane classification scheme of IVD degeneration. MRI = magnetic resonance imaging; IVD = intervertebral disc. 1 A sagittal and 1B: transverse plane image of non-degenerated MRI grade 1 intervertebral disc (IVD). 2 A sagittal and 2B: transverse plane image of mildly degenerated MRI grade 2 IVD. 3 A sagittal and 3B: transverse plane image of moderately degenerated MRI grade 3 IVD. 4 A sagittal and 4B: transverse plane image of severely degenerated MRI grade 4 IVD.Back to article page
