Synopsis
High-quality cardiac MRI at 3T in sedated children with congenital heart disease (CHD) is challenging, because of field inhomogeneities and free breathing motions. Therefore, we aimed to employ the non-contrast free-breathing generic T1-weighted turbo-field echo (TFE) sequence with compressed sensing reconstruction for assessment of vessel diameters and evaluation of the intra- and extracardiac structures in children with CHD aged <5 years. Our results show a highly reliable clinical applicability for intra- and extracardiac structures with significantly higher accuracy in comparison to contrast-enhanced MR-angiography and 3D-Dixon sequences.
