Routine brain MRI is many times not able to detect certain important features of the pediatric brain tumors and many times have limited role. Advanced brain MRI techniques are very much helpful to improve diagnostic performance in pediatric patients of the brain tumors. Advanced MRI techniques used for evaluating pediatric brain tumors include diffusion–weighted imaging, diffusion tensor imaging, perfusion imaging and spectroscopy. In this study, we review advanced MRI techniques and interpretation algorithms for pediatric brain tumors.
