Fast multiparametric mapping could ease the adoption of quantitative MRI in clinical practice. We propose a new 3D sequence (RAMSES) which toggles the readout modality between mono- and multi-gradient echo that, associated with the acquisition of one or several spoiled gradient echo images, can provide maps of T1, T2*, B1 and net magnetisation, M0. Results show the feasibility of RAMSES for accurate and precise relaxometry mapping within a clinically reasonable acquisition time.
