A A T1wMRI scan showed homogeneous low-signal intensity within the femoral head (before operation, dog in Group A). B A T2wMRI scan showed homogeneous low-signal intensity within the femoral head (before operation, dog in Group B). C A Group A4 MRI scan showed a stripe of T1 low-signal intensity in the weight-bearing area (at 8 weeks after operation, dog in Group A). D A Group A5 MRI scan showed elliptical T2 high-signal intensity in the weight-bearing area (at 10 weeks after operation, dog in Group A). E A Group A6 MRI scan showed a stripe of T2 high-signal intensity in the weight-bearing area (at 12 weeks after operation, dog in Group A). F A Group B3 MRI scan showed a patchy T2 slightly high -signal intensity within the femoral head (at 6 weeks after operation, dog in Group B). G A Group B4 MRI scan showed a circular T2 low-signal intensity surrounding the femoral head (at 8 weeks after operation, dog in Group B). H A Group B5 MRI scan showed a stripe of T2 high-signal intensity in the weight-bearing area (at 10 weeks after operation, dog in Group B)
