The circumference, area, and volume of the SCH (Cs, As, and 3DVs) and gestational sac (Cg, Ag, and 3DVg) were automatically calculated by VOCAL. Interobserver agreement was assessed with the intraclass correlation coefficient and Bland-Altman plot. Odds ratios for the clinical and ultrasound characteristics of adverse pregnancy outcomes were estimated by univariate or multivariable logistic regression. There was high interobserver agreement in VOCAL measurements of the SCH and gestational sac (intraclass correlation coefficients, >0.900). By univariate regression analysis, women with adverse pregnancy outcomes were more likely to have vaginal bleeding, a larger As and 3DVs, and higher Cs/Cg, As/Ag, and 3DVs/3DVg ratios (all P < 0.05). In the multivariable regression analysis, a higher 3DVs/3DVg ratio of SCH (odds ratio, 1.034; 95% confidence interval [CI], 1.015-1.053; P = 0.000) and vaginal heavy bleeding had a significant positive relationship with the risk of adverse pregnancy outcomes (odds ratio, 7.846; 95% CI, 1.104-55.737; P = 0.039) remained associated with an increased risk of adverse pregnancy outcomes.

ImageJ processing software was used to determine the x (transverse), y (anterior-posterior), and z (craniocaudal) coordinates for the gallbladder neck and fundus in 544 consecutive computed tomography examinations. The differences in the fundal and neck coordinates were used to determine the likelihood of moving a stone from the neck to the fundus for the left and right lateral decubitus positions ( x coordinates), the prone position ( y coordinates), and the upright position ( z coordinates).
