Objective. To assess the agreement of 3‐dimensional ultrasonography and magnetic resonance imaging in estimating fetal lung volume in cases with isolated congenital diaphragmatic hernia. Methods. Fetal lung volume was measured in 11 cases of congenital diaphragmatic hernia (10 left and 1 right) by 3‐dimensional ultrasonography and magnetic resonance imaging. These examinations were performed during the same week. The operators were blinded to each other's results. Intraclass correlation was used to evaluate the agreement between 3‐dimensional ultrasonography and magnetic resonance imaging estimations of the ipsilateral, contralateral, and total fetal lung volume. A Bland‐Altman graph was plotted to detect possible discordant observations. Results. The global intraclass correlation coefficient between magnetic resonance imaging and 3‐dimensional ultrasonographic measurement of fetal lung volume was 0.94 (95% confidence interval, 0.78–0.98) with no outliers observed on the Bland‐Altman plot. Conclusions. There is a good agreement between 3‐dimensional ultrasonography and magnetic resonance imaging for fetal lung volume estimation in cases with congenital diaphragmatic hernia.
