ROIs	OA group (n = 20)	Control group (n = 20)	t	P
wbFC (T1Gd, ms)	380.0 ± 47.8	400.3 ± 51.5	−1.224	0.236
pFC (T1Gd, ms)	391.0 ± 66.3	393.6 ± 57.9	−0.183	0.857
FC (T1Gd, ms)	386.7 ± 50.7	397.5 ± 52.3	−0.745	0.465
TC (T1Gd, ms)	429.6 ± 59.9	448.6 ± 62.5	−1.013	0.324

The data were presented by mean ± SD. wbFC: Weight-bearing femoral cartilage; pFC: Posterior nonweight-bearing femoral cartilage; FC: Femoral cartilage; TC: Tibial cartilage; SD: Standard deviation; OA: Osteoarthritis; ROIs: Region of interests.
