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.
