Inspired by recent developments in combined relaxometry-diffusion imaging and growing interests in T2* imaging, this study achieves simultaneous compartmental T2 and T2* mapping for the first time. We take advantage of the recently developed diffusion-PEPTIDE imaging technique, which allows for efficient acquisition of diffusion datasets with varying T2/T2* contrast. A relaxometry-diffusion combined microstructure model and a robust multi-stage fitting approach are developed to enable compartmental T2 and T2* mapping. This technique could be a new tool for future neuroimaging studies benefiting from quantification of T2-T2*-diffusion, such as studying iron content related development and pathology.
