Image-based respiratory navigation (iNAV) may overcome the problems of respiratory artifacts and long scan time in whole-heart MRI. In this study we compared iNAV to the gold standard 1D diaphragmatic navigator (1DNAV) in 28 non-anaesthetised patients with congenital heart disease. Whole-heart MRI using iNAV significantly reduced scan time, while improving qualitative and quantitative image quality scores compared to 1DNAV.
