In pregnancies where fetal congenital heart disease is suspected during routine obstetric ultrasound, a thorough echocardiographic workup is required to assess the fetal cardiac anatomy and function. MRI has been increasingly proposed as an adjunct diagnostic tool to evaluate the fetus. In this work, we present a newly developed method for reconstructing high-resolution dynamic MR images of the fetal heart, evaluate this modality in the context of visualizing cardiac abnormalities, and compare to echocardiography. We show that MRI of the fetal heart has the potential to compliment echocardiography in the assessment of congenital heart disease.
