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.
