The feasibility of cardiac triggered diffusion data acquisition in a pediatric population was investigated. Data was collected with and without cardiac triggering either along the z gradient direction and then subjected to bootstrap statistics (3 subjects) or in 15 non-collinear directions and fitted to a tensor model (3 subjects). We found that cardiac triggering decreases the variability in the data without a significant increase in acquisition time in the investigated pediatric population.
