Conventional MRI images of brain tumours likely underestimate the true extent of tumour and have variable sensitivity in diagnosis depending on tumour type. In this study, DTI scans were acquired from 94 patients with a range of brain tumours. We present a novel whole brain segmentation and visualisation technique which reveals potential tumour-specific diagnostic characteristics. Discriminant analysis of tumour characteristics reveals diagnostic sensitivities ranging from 84-100%
