The commonly used method to evaluate the fetal heart is echocardiography (ECG). However, the detection of congenital heart diseases by ECG varies from 45% to 74% and an alternative imaging modality would be desirable. Fetal cardiac MRI has the potential to visualize anatomy and to assess functional parameters of the fetal heart. External fetal cardiac gating using a newly developed Doppler ultrasound sensor (DUS) has been introduced in previous studies. The purpose of this study was to perform fetal cardiac MRI as well as MR flow measurement within great vessels using for external fetal cardiac gating in human fetus and to optimize the device.
