We investigate the feasibility of the accelerating 4D flow with compressed sensing and online reconstruction in pediatric patients. In-vitro models and imaging in pediatric patients was performed and hemodynamic quantification was compared to conventional approaches. The results demonstrated flow metrics and clinically relevant indices measured by 6-fold accelerated CS were in good agreement with those measured by conventional acceleration techniques, with scan time savings of 30.2%. This suggests the feasibility of using CS 4D flow for pediatric patients in the clinical setting.
