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

Abstract

Hydrocephalus is a condition characterized by abnormal cerebrospinal fluid flow and is usually diagnosed through shape measurements of the ventricular system. In this work, actual brain and skull geometries obtained from MRI scans are incorporated into numerical simulations of the cerebrospinal fluid flow throughout the brain parenchyma Intracranial pressure and fluid velocity fields in the brain tissue in hydrocephalus are calculated using finite element methods. A case-study is used to summarize the procedure.
