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.
