Fig. 5From: T1ρ, T2 and T2* mapping of lumbar intervertebral disc degeneration: a comparison studyBox plots of the values in nucleus pulposus (NP) aaccording to the morphologic changes of disc degeneration. For comparisons of normal, bulging discs and herniated discs, A, B and C are respectively T1ρ, T2 and T2* relaxation time of NP. For comparison of no tear and annular tears, D, E and F are respectively T1ρ, T2 and T2* relaxation time of NP. ** P < 0.01Back to article page
