Answer

MRI is the imaging modality of choice for the diagnosis and follow-up of infants with moderate-to-severe hypoxic-ischemic encephalopathy (HIE). [41, 42, 43, 44] Conventional MRI sequences (T1w and T2w) provide information on the status of myelination and preexisting developmental defects of the brain. When performed after the first day (and particularly after day 4), conventional images may accurately demonstrate the injury pattern as area of hyperintensity. Conventional images are most helpful at age 7-10 days, when the diffusion-weighted imaging (DWI) findings have pseudonormalized.
