简要总结
We will test an ultrasound device that uses sound waves to detect the fetal heart beat, and use this device to tell the MRI scanner when to collect pictures of the fetal heart. This will help freeze motion of the fetal heart, to make MRI pictures sharper. This will be important for assessing human fetal heart disease, an active area of research at our institution.

结局指标
主要结局
Comparison between fetal MRI and fetal echocardiography
时间窗: within 2 weeks of participation in the study
Anatomic MR images of the fetal heart will be acquired using prospective gating information from the Doppler ultrasound probe (SMART-SYNC LM03) and used to calculate ejection fraction. These values will be compared with corresponding reference values obtained during the patient's visit to the Fetal Echocardiography Clinic.
