a T1Pre and T1Gd values after intravenous injection of Gd-DTPA2− (0.2 mmol/kg body weight), in posteromedial healthy (n = 12; closed circles), pathological grade 2 (n = 11; open circles) and pathological grade 3 (n = 7; closed triangles) menisci. T1Gd was longer in the pathological grade 2 menisci (p = 0.027, ANOVA) and showed no difference in the pathological grade 3 menisci compared to the healthy menisci. b ΔR1 values in posteromedial healthy (n = 12; closed circles), pathological grade 2 (n = 11; open circles) and pathological grade 3 (n = 7; closed triangles) menisci, after an intravenous injection of Gd-DTPA2− (0.2 mmol/kg body weight). The values were lower in the pathological grade 2 menisci (p = 0.046, ANOVA) and tend to show higher values in the pathological grade 3 menisci (p = 0.110, ANOVA) compared to the healthy menisci
