AB  - AIMS: To evaluate the role of four-dimensional (4D) ultrasound with B-flow 
      imaging and spatiotemporal image correlation (STIC) in the evaluation of normal 
      fetal heart and congenital heart disease during pregnancy. METHODS: Volume data 
      sets of the fetal heart were acquired with automated transverse and longitudinal 
      sweeps of the anterior chest wall. We studied 31 normal fetuses and 28 fetuses 
      with congenital heart disease (6 with double-outlet right ventricle, 5 with 
      complete transposition of great arteries, 8 with tetralogy of Fallot, 3 with 
      right aortic arch, 2 with persistent left superior vena cava, 3 with truncus 
      arteriosus communis, and 1 with interruption of aortic arch) at gestation ages 
      ranging from 18 to 39 weeks using transabdominal 4D B-flow sonography with STIC 
      (4D BF-STIC). RESULTS: Four-dimensional BF-STIC demonstrated dynamic angiographic 
      features in both normal and abnormal fetal hearts. Four-dimensional BF-STIC 
      images could not be obtained in two normal fetuses at 18.9 and 35.6 weeks because 
      of the high fetal heart rate and inappropriate fetal position. Of the other 29 
      fetuses all extracardiac vessels such as aorta, pulmonary artery, ductus 
      arteriosus, inferior vena cava, and ductus venosus could be detected on 
      reconstructed images. In seven normal cases, a 4D image was recorded to allow 
      simultaneous visualization of all four pulmonary veins. In the 28 fetuses with 
      cardiac anomalies, 4D sonography with B-flow imaging and STIC detected the 
      "digital casts" of the outflow tracts, great arteries, and veins draining into 
      the heart. These results demonstrate spatial relationship among these structures 
      which provide important anatomical information. CONCLUSION: Four-dimensional 
      BF-STIC provides a means of real time three-dimensional evaluation of fetal 
      extracardiac hemodynamics in the second and third trimesters. This novel 
      technique assists in the evaluation of fetal cardiac hemodynamics and may play an 
      important role in future fetal cardiac research and in the identification of 
      anatomical features of different congenital cardiac anomalies.
