Abstract / Description of output

BACKGROUND: Cardiac magnetic resonance (CMR) is the gold standard for the evaluation of the right ventricle (RV) in congenital heart disease (CHD). Novel compressed sensing (CS)-based single-breath-hold multislice CMR cine techniques have emerged to accelerate data acquisition. The aim of this study was to compare a CS-CMR cine technique with the standard multi-breath-hold technique cine images for the assessment of RV volumes and function.METHODS: The CS-CMR acquires 2 long-axis and 3 short-axis cine in 1 single breath-hold. To measure RV ejection fraction (RVEF(CS)) and RV volumes, a non-model-based 3D reconstruction software was used (figure). For comparison, a conventional stack of multi-breath-hold short axis cine was acquired. As a reference for the RV stroke volume (RVSV), pulmonary antegrade flow was measured by phase-contrast CMR in the main and both pulmonary branch arteries.
