From: Dual-phase whole-heart imaging using image navigation in congenital heart disease

Reformatted dual-phase 3D WH bSSFP data from two healthy subjects in systole and diastole. This figure shows that in some subjects with poor dNav gating, excessively long scan times can result in worse image quality. iNAV = image-navigator; dNAV = diaphragmatic 1D pencil beam navigator. Arrows highlight coronary segments with improved sharpness using iNAV compared to dNAV
