3D printed models from MRI scans can effectively demonstrate the surface structure of the brain. Previous workflows focus on adult brains as a basis for prints. Our database of pediatric MRI brains who had perinatal hypoxic ischemic injury and presented late for imaging, with pathology causing cortical surface irregularities and parenchymal cysts. Difficulties arise in accurate depiction of the cortex on 3D print models in these pathologic brains. We aim to demonstrate effective workflows to accurately and efficiently print 3D models of especially pathologic pediatric MRI brains. Also, to critically and empirically test and refine the various steps involved in producing 3D print models which include segmentation of the MRI volume into tissue classes, generation of a surface model from this volume, preparation and final print of a 3D model.

Hypoxic ischemic injury (HII) is a leading cause of neonatal encephalopathy and resultant cerebral palsy. Most studies focus on early magnetic resonance imaging (MRI) findings and patterns of injury, with few studies evaluating patterns in delayed MRI of patients with cerebral palsy.
We aim to categorise the delayed imaging MRI findings and distribution of abnormalities in a large cohort of children with cerebral palsy and obtained for medicolegal purposes to determine the causes of cerebral palsy, and to map the frequency of anatomic involvement in those with hypoxic ischemic injury.
