From: In vivo experimental intervertebral disc degeneration induced by bleomycin in the rhesus monkey
Mean %DHI, T1ρ values of NP and AF at each time point. (A) A significant decrease of %DHI was observed at 12 months postoperatively in the bleomycin group (*P < 0.05). (B) A significant decrease in the T1ρ values of NP was observed at 3 months postoperatively in the bleomycin group (*P < 0.05), followed by a rapid decrease during the second 3 months. (C) A significant decrease in the T1ρ values of AF was observed at 6 months postoperatively in the bleomycin group (*P < 0.05), followed by slowly decrease. DHI: Disc height index; NP: nucleus pulposus; AF: annulus fibrosus.
