From: Dynamic fetal cardiovascular magnetic resonance imaging using Doppler ultrasound gating
Multiple Phases of DUS Gated Cine Images. DUS-gated balanced SSFP cine images (20 phases) of the fetal heart in the 4-chamber view (gestational week 36). DUS gating allowed for clear differentiation of the myocardium versus lumen throughout the cardiac cycle. Symmetric contraction of the ventricles and expansion of the atria is seen with maximum ventricular contraction and minimum ventricular blood volume in cardiac phases 10–12
