Disc injury results in progressive degenerative changes in the lumbar spine at 6 and 15 weeks. Representative T2-weighted sagittal (A-E) and axial (F-J) MRI images at 6 and 15 weeks obtained post-mortem using 14T MRI. Red arrows on sagittal images indicate severe disc degeneration characterized by loss of bright signal seen at uninjured levels.
