Yeo L, et al. – This study is performed to assess the performance of color and bidirectional power Doppler ultrasound combined with Fetal Intelligent Navigation Echocardiography (FINE) in analyzing the fetal heart. The FINE method applied to STIC volumes of normal fetal hearts acquired with color or bidirectional power Doppler information can generate successfully eight to nine standard fetal echocardiography views (via grayscale, color Doppler or power Doppler) in the second and third trimesters. Color Doppler FINEshows effectively abnormal anatomy and/or Doppler flow characteristics in cases of CHD.
