The recent development of a self-gated framework to reconstruct cardiac cine MR images without the need for an external ECG signal has opened the door to prenatal cardiac examination with MRI. This study investigates the potential of this technique for fetal cardiac MRI and compares its performance with the clinical gold standard echocardiography. Standard views from clinical fetal echocardiographic examinations were acquired with both imaging modalities and two experienced readers independently compared them qualitatively and quantitatively. The results showed good agreement between the two modalities and validate the use of MRI for prenatal evaluation of the heart.
