Fig. 4.

Intra-dictionary repeatability of magnetic resonance fingerprinting (MRF)–derived radiomic features across conventional imaging and MRF with dictionaries of different step sizes. (a) First-order features and (b) symmetrical gray level co-occurrence matrix are shown. Spherical volume of interests was used. Conventional refers to conventional 3D T1-weighted imaging. ICC, intraclass correlation coefficient; 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
