Abstract:
Objective To investigate the consistency of fetal gallbladder volume (FGV) during middle-late pregnancy with three-dimensional ultrasonic virtual organ computer-aided analysis (VOCAL) technique at different rotation angles,and to analyze the correlation between FGV and gestation age.Methods A total of 157 healthy pregnant women underwent prenatal screening were included.The reference range of FGV was measured with three-dimensional ultrasonic VOCAL at 30°,18° and 12° rotation angle,respectively.The correlation between FGV and gestation age was observed,and the consistency of FGV values measured with VOCAL at different rotation step angles was compared.Results The correlations between FGV values measured with VOCAL at 30°,18°,12° rotation step angles and gestation age were all excellent (r=0.92,0.88,0.90;all P＜ 0.001).The consistency of FGV values measured with VOCAL at different rotation step angles was very good (30° and 18°,ICC=0.94;30° and 12°,ICC=0.97;18° and 12°,ICC=0.94).Conclusion Three-dimensional ultrasonic VOCAL can be used to establish the reference range of fetal gallbladder volume in middle-late pregnancy.The consistency of FGV values measured with VOCAL at different rotation step angles was very good,and the correlation between FGV and gestation age was excellent.
