ABSTRACT
Objective To explore the feasibility of spatiotemporal image correlation (STIC) and virtual organ computeraided analysis (VOCAL) in assessment of fetal cardiac ventricular wall volume.Methods Two hundred and forty-seven normal singleton pregnancies from 22 week to 32+6 week were analyzed.The intraclass correlation coefficient (ICC) was used to assess intra-observer and inter-observer concordance.The ventricular wall volume of 14 fetuses with cardiac disor ders were evaluated.Results There was good correlation between the mean wall volume and gestational age (GA)The volume of left cardiac ventricular wall=-6.542 + 0.339 × GA (r2 =0.98),while the volume of right cardiac ventricular wall=-7.509+0.384 × GA (r2 =0.74).The intra-observer and inter-observer concordance in assessing the volume of the right (ICC=0.994,0.888) and left ventricular wall (ICC=0.995,0.972) were good.The volume of the right and left ventricular wall were altered (<5th percentile and/or >95th percentile) in 6 fetuses of 14 fetuses with cardiac disorders.Conclusion The reference ranges for the volume of the right and left ventricular wall can be calculated with three-dimensional ultrasound using STIC and VOCAL,and the reproducibility is good.
