Fig. 2.

Representative magnetic resonance fingerprinting (MRF) maps and a histogram of each dictionary with different step sizes. Representative T1 maps generated from different dictionaries in axial, coronal, and sagittal views (upper 3 rows). Representative spherical volume of interest with a diameter of 20 mm is indicated by transparent green color. Since datasets for each subject are inherently aligned in MRF, each volume of interest was copied and pasted across all datasets. Note that the images obtained from different dictionaries are challenging to distinguish visually. Histogram of T1 values for each dictionary (bottom row). Note that the sparser dictionary has coarser discretization values
