Figure 4: 3T sagittal T2 weighted MRI image of a lumbar spine from animal 9480, sacrificed at 12 weeks. Non-injured adjacent level controls (L1/2, L5/6), represented by blue arrows, and scored Pfirrmann 1. Injured discs L2/3, L3/4 and L4/5, represented by red arrows, scored Pfirrmann 2. As can be seen all injured discs (red arrows) demonstrate an inhomogeneous disc structure with grey banding. Adjacent controls (blue arrows) demonstrate a homogenous bright white structure.
