The value of MRI in congenital heart disease (CHD) is well-recognized. However, high time overhead and the requirement for expert oversight of image acquisition impede its more widespread use. Ferumoxytol-enhanced 4-dimensional multiphase imaging with contrast (4D-MUSIC) is a cardiac phase-resolved MR technique that generates highly detailed images under controlled ventilation. Our early multi-center experience demonstrates that 4D-MUSIC provides value-added imaging in CHD by shortening the examination time, simplifying the imaging protocol, and providing reliable, gadolinium-free, high spatial resolution, cardiac phase-resolved images. When combined with locally available velocity mapping, 4D-MUSIC enables comprehensive imaging of complex CHD in less than 40 minutes.
