FOLH1 and neoplasm: Further, logistic regression did not show a relationship between the presence of a diffusion restriction within the tumor in the DWI (dichotomized into diffusion restriction present or not present) and the PSMA uptake using the SUVmax of the tumor (odd ́s ratio 0.93; 95% CI 0.45-1.84) or the H-score of the immunohistochemical endothelial PSMA expression (odd ́s ratio 1.01; 95% CI 0.96-1.06).
