MR quantitative T1ρ mapping has gained increasing attention due to its capability in studying low-frequency motional processes and chemical exchange in biological tissues. At ultra-high fields, the chemical exchange and proton diffusion in biological tissues should be more prominent. In this study, for the first time, we aim to test the feasibility of T1ρ mapping of brain at 5T and evaluate the T1ρ values estimated from datasets using both 3T and 5T scanners.
