Fig. 5From: Apparent diffusion coefficient restriction in the white matter: going beyond acute brain territorial ischemiaMagnetic resonance images obtained in an asymptomatic, phenylketonuric adult who was treated early (plasmatic phenylalanine levels of 729 μmol/l n.v. 44–66 μmol/l). Axial diffusion-weighted (a) ADC maps (b) and T2-weighted images (c) showed periventricular white matter signal abnormalities predominantly in the parieto-occipital regions (arrows)Back to article page
