In this study 50 pediatric brain tumors were analysed in the intial(preop.), early (one month postop.) & late follow up(six months postop.) for determining the treatment outcome using the ADC values as well as specteroscopic metabolites peaks & ratios.We correlated all the available values in our results including ADCvalue, NAA, tCho which were discussed both alone and as combined relations and their statistical significance & p values were calculated. Statistically significant results were found in combining diffusion values & MRS findings.
