Detailed understanding of the pulsatile motion of the
cerebrospinal fluid (CSF) and its importance to maintain
brain health still remains enigmatic. 4D PC MRI flow
measurements allow evaluating the complexities of the
CSF flow patterns in diseases such as Chiari I
Malformation. Computational fluid dynamics (CFD)
simulations have provided detailed information about the
CSF flow field. The first comparison of 4D PC MRI
measurements to CFD of CSF flow in the craniocervical
junction has recently been employed. This study aims to
assess the inter-operator variability of the 3D rigid
wall CFD simulations of the CSF flow in the
craniocervical junction.
