We considered the steps needed to analyse Diffusion Tensor Imaging (DTI) cross-sectionally and longitudinally, following a state-of-the-art approach which takes into account image quality, acquisition consistency, artifact correction, spatial correspondence. We applied this method to a small cohort of frontotemporal dementia (FTD) patients and controls to replicate the findings in the existing literature.
