Abstract:
Nomograms of the fetal lateral ventricles were obtained by the transvaginal approach. Three hundred low-risk women with no sonographically apparent fetal anomalies were scanned prospectively in a cross-sectional study. Three measurements in the parasagittal plane, three in the midline coronal plane, and two in the posterior coronal plane were used to generate seven nomograms. Two additional nomograms reflecting two calculated ratios also were created. A mean regression line and the 5th and 95th confidence intervals were determined. We concluded that transvaginal sonography of the fetal brain generates images of both hemispheres of good enough resolution to allow several precise and reproducible measurements.
