Eighty-one patients with historically confirmed PCa
underwent two repeated 3T DWI examinations performed using 14 b-values in the
range of 0-500 s/mm2 and diffusion time of 19.004 ms. Various fitting methods
for IVIM and mathematical models were evaluated in the terms of fitting quality
(Akaike information criteria), repeatability, and Gleason score prediction. Monoexponential
model demonstrated the highest repeatability and clinical values
in the regions-of-interest based
analysis of PCa DWI, b-values
in the range of 0-500 s/mm2.
