Cardiovascular MRI is an excellent diagnostic tool for children with congenital heart disease (CHD), but the long acquisition times, and need for sedation/anesthesia and the administration of a gadolinium-based contrast results it only accounts for only 2% of pediatric cardiac diagnostic tests. Our 20-min, free-breathing, non-contrast cardiovascular magnetic resonance (CMR) protocol is potentially a game-changer, because its total scan time (20 min) is considerably shorter than a standard protocol (90 min) and does not require anesthesia or gadolinium-based contrast agent.
