Track density imaging (TDI) mapping method has been developed to dramatically increase the spatial resolution of diffusion-weighted imaging (DWI) data beyond the acquired resolution. However, it is not clear if TDI maps can be used to reliably to quantify differences in brain populations. This project aims to characterise short track TDI (stTDI) in terms of stability and reproducibility as a quantitative tool for group comparison of brain structures.
