Hydrocephalus: A Realistic Porous-Media Model with Geometry Based on Neuroimaging

Abstract

Hydrocephalus is a condition characterized by abnormal cerebrospinalfluid flow and is usually diagnosed through shape measurements of theventricular system. In this work, actual brain and skull geometriesobtained from MRI scans are incorporated into numerical simulations ofthe cerebrospinal fluid flow throughout the brain parenchymaIntracranial pressure and fluid velocity fields in the brain tissue inhydrocephalus are calculated using finite element methods. A case-studyis used to summarize the procedure.
