MR imaging of the fetal heart presents multiple challenges in terms of the small size of the heart and great vessels, fast fetal heart rate and uncontrolled fetal motion during acquisition. This presentation outlines the recent technical innovations designed to overcome these limitations, with referenced examples of static 2D and 3D imaging, as well as time resolved 3D data and even 4D flow sequences. Future developments are also discussed as well as current and future clinical applications.
