An example of a fetal CMR cine image corrupted by fetal motion and lack of gating (left). No cardiac structures can be clearly seen. Corresponding image (right) acquired using Doppler-ultrasound gated cine bSSFP optimized for fetal heart size and heart rate. Left (LV) and right (RV) ventricles, atria, mitral and tricuspid valves, and descending aorta (DAo) are clearly depicted.
An example in which ultrasound was challenging: no fully diagnostic images, but suspicion of ventricular asymmetry with narrow aorta. Fetal CMR in gestational week 35 shows normal systolic function, and in the 3-chamber view a normal-sized aortic annulus and ascending aorta.
