a

– significantly different than PZ (p<0.001)

b

– significantly different than CG (p<0.001)

c

– significantly different than CG (p<0.01)

<D> – mean diffusivity, FA – fractional anisotropy

Ktrans – volume transfer constant, ve – fractional volume of the extra-vascular extra-cellular space, vp – fractional plasma volume

PCa – prostatic adenocarcinoma (DTI: n = 25, DCE MRI: n = 19), PZ – normal peripheral zone (DTI: n = 147, DCE MRI: n = 133), CG – central gland (DTI: n = 40, DCE MRI: n = 40)
