Fig. 3From: Evaluation of intervertebral disc degeneration in young adult asymptomatic Dachshunds with magnetic resonance imaging and radiographyDistribution of different MRI grades (1–4) and overall IVD degeneration per dog. MRI = magnetic resonance imaging; IVD = intervertebral disc; MRI grade 1 = non-degenerated IVD; MRI grade 2 = mildly degenerated IVD; MRI grade 3 = moderately degenerated IVD; MRI grade 4 = severely degenerated IVD. X-axis represents the 21 Dachshunds. The MRI grading results of each dog are at the bottom of the Y-axis and the MRI total sum is at top of the Y-axis. The MRI total sum indicates the degree of overall IVD degeneration in each individual and is calculated by summing MRI grades of all 26 discs. The higher the column, the more advanced the overall IVD degenerationBack to article page
