1. A method for multi-dimensional, relaxation-diffusion magnetic resonance fingerprinting (MRF), the method comprising:
performing, using a magnetic resonance imaging (MRI) system, a pulse sequence that integrates free-waveform b-tensor diffusion encoding into a magnet resonance fingerprinting pulse sequence to perform a multi-dimensional, relaxation-diffusion encoding while acquiring MRF signal evolutions;
processing, using a processor, the acquired MRF signal evolutions to determine at least one relaxation parameter and at least one diffusivity parameter; and
generating, using the processor, a report including at least one of the at least one relaxation parameter and the at least diffusivity parameter.
