MRI of the brain performed in the subacute phase of HIE. DWI hyperintensity is noted in the deep grey nuclei and extensively in the cerebral cortices (arrows) on axial DWI image (a). There is no signal drop on axial ADC image (b). Diffuse cortical swelling and signal changes (arrows) are appreciated better on the axial T2W image (c). Minimal intraventricular blood (dashed arrow) is seen on axial GRE image (d). Axial source 3D-TOF MRA image (e) and reconstructed maximum intensity projection MRA image of Circle of Willis (f) show no flow signal in the intracranial arteries
