The purpose of this study was to develop an experimental
4D Flow MRI setup as verification of a CFD TCPC model.
4D Flow MRI was performed in two TCPC subjects. Anatomy
was segmented from PC-angiograms and converted to a 3D
geometry to fabricate physical models and for CFD
analysis. Physical models were connected to a perfusion
system and imaged using the in vivo protocol. Results
for in vivo and in vitro 4D Flow MRI and CFD show
comparable velocities and flow distribution. This study
connects CFD and 4D Flow MRI for improved TCPC
assessment.
