Whole-heart 3D water-fat imaging during free-breathing can provide high-resolution fat-suppressed morphological images in patients incapable of holding their breath. In this work we evaluated a 3D chemical-shift-encoded pulse sequence with ECG gating and navigators in 15 patients referred for a wide variety of clinically-indicated cardiac MRI exams. Images were graded by two experienced radiologists on a 4-point scale for overall image quality and level of residual artifacts. Diagnostic images of good/excellent quality were obtained in all patients.
