Three dimensional magnetic resonance angiography (3DMRA) and two-dimensional phase contrast are commonly used for assessment of anatomy and flow in congenital heart disease. Time-resolved, three-dimensional phase contrast MRI (4D flow) provides complete volumetric coverage of the chest with flow assessment in any plane. How the addition of ferumoxytol (Fe), a blood pool contrast, changes 4D flow magnitude image quality relative to extracellular gadolinium-based contrast agents (GB) and non-contrast (NC) exams is unknown. We compare image quality measurements in Fe, GB and NC 4D flow with ECG-gated, respiratory-navigated 3DMRA.
