Average MTR values at 1.2 ppm inside the tumor for each model group. There was a significant decrease in MTR values from day 6 to day 8 (P < 0.05) and from day 6 to day 10 (P < 0.01) after transplantation. However, there was no significant decrease from day 8 to day 10 after transplantation (P = 0.76).
