Thirteen patients with a total of 18 brain tumors undergoing first or second line treatment were examined before, during and after treatment using quantitative MRI measuring T1, T2 and ADC. Two weeks after treatment start a significant decrease in ADC and T1 was observed in patients with tumor progression. Six weeks after treatment start a significant change associated with treatment response could be seen in all parameters. There seemed to be a difference between first line and second line treatment; however more data is needed to investigate that relationship further.
