Effect of magnetic resonance fingerprinting (MRF) dictionary step size on symmetrical gray level co-occurrence matrix. (a) Inter-dictionary percent relative change of radiomic features. (b) Intraclass correlation coefficients (ICCs) for each feature (rows) extracted with different dictionary step sizes (columns). Radiomic features obtained from the highly dense dictionary were used as references based on the assumption that the highly dense dictionary contained the greatest amount of information. Spherical volume of interests was used. Id, inverse difference; Idn, inverse difference normalized; Idm, inverse difference moment; Idmn, inverse difference moment normalized; Imc, informational measure of correlation; MCC, maximal correlation coefficient
