3D FSE (left) and 3D bSSFP (right) images of a 6 month old patient with a pulmonary artery band (as palliation for an unbalanced atrioventricular septal defect). The pulmonary artery anatomy (which is vital for subsequent surgical planning) is clearly seen with 3D FSE (arrow) but not 3D bSSFP (right) due to dephasing artifact from turbulent flow after the band. The patient went on to have an uneventful cavopulmonary anastomosis. AAo = ascending aorta; MPA = main pulmonary artery; RPA = right pulmonary artery; LPA = left pulmonary artery
