In this work we optimize ATR-bSSFP with respect to contrast and fat saturation for abdominal imaging. To do so we used simulations and validated them with phantom measurements. After validation, we use the simulations to determine optimal settings with respect to contrast between abdominal organs. We then confirm the optimal contrast settings in vivo in two healthy volunteers and a patient with pancreatic cancer.
