Purpose This study explores the possibility of using gradient echo‐based sequences other than balanced steady‐state free precession (bSSFP) in the magnetic resonance fingerprinting (MRF) framework to quantify the relaxation parameters . Methods An MRF method based on a fast imaging with steady‐state precession (FISP) sequence structure is presented. A dictionary containing possible signal evolutions with physiological range of T 1 and T 2 was created using the extended phase graph formalism according to the acquisition parameters. The proposed method was evaluated in a phantom and a human brain. T 1 , T 2 , and proton density were quantified directly from the undersampled data by the pattern recognition algorithm. Results T 1 and T 2 values from the phantom demonstrate that the results of MRF FISP are in good agreement with the traditional gold‐standard methods. T 1 and T 2 values in brain are within the range of previously reported values. Conclusion MRF‐FISP enables a fast and accurate quantification of the relaxation parameters. It is immune to the banding artifact of bSSFP due to B 0 inhomogeneities, which could improve the ability to use MRF for applications beyond brain imaging.
