We here present a proof of concept for a new quantitative MT mapping sequence using spin and stimulated echoes. The approach is based on the fact, that the labeled magnetization of the STEAM signal follows an double-exponential decay due to MT. With the help of a T1 map, a single acquisition with just one mixing time and an integrated spin echo allows to map the fraction of the bound proton pool.
