Note.—NA indicates not applicable because procedure not performed; ?, equivocal; HIE, hypoxic-ischemic encephalopathy; Global, generalized abnormality. Note that anatomic sites as listed under Follow-up Imaging had one or more of the following: atrophy, abnormal MR imaging signal, or abnormal CT attenuation.

^*Caudate nuclei were not separately assessed.
