Fetal CMR is difficult due to the lack of an ECG signal, fetal motion, small anatomic sizes and high fetal heart rates. Initial results are presented which use a doppler ultrasound gating device to capture fetal cardiac motion in standard cardiac views and blood flow was quantified with 4D flow MRI. bSSFP cine images were scored for image quality by two radiologists and flow in the umbilical vein, ascending aorta and main pulmonary artery were quantified and agreed well with reported values. Unique insight was provided with dynamic imaging regarding the fetal circulation and the impact of congenital disease.
