Objective To investigate the feasibility of sonography-based volume computer aided system(SonoVCADS)in displaying normal fetal hearts diagnostic sections.Methods Sixty-six normal singleton fetuses who underwent fetal cardiac examination at the department of ultrasound in Lishui Central Hospital from August 2021 to March 2022 were included.Three hundred and fourteen volume images were obtained using SonoVCADS.Each diagnostic section was scored by three observers with different experiences and the success rate and consistency of SonoVCADS in displaying eight diagnostic sections were calculated.The time consumed by the three observers in displaying fetal cardiac diagnostic sections using SonoVCADS was compared.Additionally,50 fetuses were randomly selected to compare the time in displaying diagnostic sections using SonoVCADS and two-dimensional echocardiography.Results The success rate in displaying eight diagnostic sections of fetal heart using SonoVCADS was not significantly different among the three observers(all P＞0.05).Taking observer B(relatively inexperienced)as an example,70.70%of volume images successfully displayed 8 diagnostic sections,13.69%of volume images displayed 7 diagnostic sections,and only 4.15%of volume images displayed less than 4 diagnostic sections.The Kappa values for observer B in displaying eight diagnostic sections ranged from 0.652 to 0.854,which ranged from 0.536 to 0.752 for the three observers.Observer C(more experienced)spent significantly less time than observers A and B(both P＜0.05).The time in displaying eight diagnostic sections by observer C was significantly less using SonoVCADS than using two-dimensional ultrasound(P=0.018).Conclusion SonoVCADS exhibits a high success rate in displaying eight diagnostic sections of fetal heart,with low operator dependence,favorable consistency and diagnostic efficiency.
