A multivariable linear regression analysis found no relationship of the ADC value of the [68Ga]Ga-PSMA PET/MRI with the SUVmax of the tumor (p = 0.50; t = 0.70; F = 0.50) or with the H-score of the immunohistochemical endothelial PSMA expression (p = 0.67; t = 0.45; F = 0.20), with an R2 of 0.06. Here, FOLH1 is linked to neoplasm.
