Representative cardiac cine SSFP images with multiple signal averages (MN) and respiratory triggered (RT) acquisition techniques in an unsedated free-breathing 14 year old female with Down syndrome and status post Tetralogy of Fallot repair. Three representative short axis slices from the base (top row), mid chamber (middle row) and apex (bottom row) are presented. The MN images on the left demonstrate subtle blurring of the myocardium and trabeculae, best visualized on the apical slice, while the RT images on the right show significant improvement in edge definition.
