The invention belongs to the technical field of magnetic resonance imaging, and provides a quantitative magnetic resonance imaging parameter determination method, device and equipment and a storage medium. The method comprises the steps that a plurality of magnetic resonance images of a tested subject are acquired based on a preset MRF pulse sequence, and an evolution signal of each voxel is extracted from the plurality of magnetic resonance images; the transverse relaxation time of each voxel is determined according to an analog signal matched with the corresponding evolution signal of each voxel in a preset dictionary, wherein the MRF pulse sequence comprises a plurality of radio frequency pulse strings excited in sequence, and the radio frequency pulse strings are used for exciting thetransverse magnetization vector of the tested object; and each evolution signal is used for representing the change of the signal strength of each voxel in the plurality of magnetic resonance images.According to the quantitat
