The T2 values calculated by GEAW workstation are used to create pseudo-color images, respectively. 1 mm2 ROI was set on cartilage to lateral to measure T2 values. Cartilage thickness was measured at same position in Sag-T1WI (not list). Due to different thresholds, different colors represent different T2 values. a–c The T2 values of TT cartilage. ROI was placed on articular cartilage of calcaneus side and talus side, respectively. Blue–red shows high–low T2 values. d–f The T2 values of pST cartilage. ROI was placed on the articular cartilage of the side of the talus and the side of the calcaneus, respectively. Red–blue shows high–low T2 values
