In a method and magnetic resonance (MR) apparatus for quantitative T1 determination in MR imaging, MR data of the volume section are acquired depending on a contrast agent administered in the examined object, wherein the MR data of the volume section are acquired several times during various phases of the diffusion of the contrast agent in the volume section. First MR data of the volume section are acquired with a first sequence and second MR data of the volume section are acquired with a second sequence, wherein the first sequence is distinguished from the second sequence only by the flip angle of at least one RF pulse in the respective sequences and/or only by the repetition time of the respective sequences. Respective T1 values of each voxel of the volume section are determined depending on the first MR data and the second MR data.
