Objective To evaluate the quality of fetal heart volumes acquired with different initial planes with three-dimensional ultrasound and investigate the value of tomographic ultrasound imaging technique in evaluation normal fetal heart.Methods The fetal heart volumes were acquired with the apical four chamber view and transversal four chamber view as the initial planes using three-dimensional ultrasound in 158 fetuses,whose gestational ages were range from 16 to 40 weeks.And then the volumes were rotated with TUI software for showing the nine standard views of four chamber view,five chamber view,three vessels-trachea view,left ventricular outflow tract view,right ventricular outflow tract view,short-axis view of great arteries,sagittal view of aortic arch,sagittal view of ductus arteriosus,superior vena cava view and inferior vena cava view.All the volumes were divided into three groups according to gestational age.The gestational age were range from 16 to 24 weeks in group A,25 to 32 weeks in group B and 33 to 40 weeks in group C.Then the display rates of the nine views were compared among the three groups.Results One hundred and forty-nine volumes were acquired in these 158 fetuses.Seventy-two volumes were acquired withthe apical four chamber view as the initial plane and 77 volumes were acquired with the transversal four chamber view as the initial plane.The display rate(2 point section rage) of the superior vena cava view and the inferior vena cava view were significantly different in A and B groups and the results were similar for both volumes acquired with the two different initial planes (χ2=4.927,22.938,6.312,21.761,all P<0.05).The display rate (2 point section rage)of aortic arch section and arterial duct arch section,in the apex cordis four cavity cherished surface,has significant differences in A and B groups (χ2=8.053,4.967,all P<0.05),as the display rate in B group is the best,that in C group is next,and that in A group is the worst.Conclusions Both of the apical four chamber view and transversal four chamber view could be used as the initial planes for acquiring fetal heart volumes with three-dimensional ultrasound.The qualities of the volumes are influenced by the external conditions.The volumes acquired with the apical four chamber view as initial plane may be impacted more significantly.The optimal time for fetal heart screening is between 25 to 32 weeks.The fetal heart volumes that are acquired with the apical four chamber view and transversal four chamber view as the initial planes are very important for the standard fetal heart screening and remote consultation.
