Purpose Magnetic resonance fingerprinting (MRF) with spiral readout enables rapid quantification of tissue relaxation times. However, it is prone to blurring because of off‐resonance effects. Hence, fat blurring into adjacent regions might prevent identification of small tumors by their quantitative...
