Abstract (EN): Objectives To determine the accuracy of measuring the corpus callosum (CC) length in reconstructed midsagittal views obtained by 3D multiplanar manipulations or volume contrast imaging in the C-plane (VCI-C) in comparison to measurements obtained by direct mid-sagittal view. Methods Forty-six normal fetuses were examined by 2D and 3D ultrasound between 23 and 32 weeks of gestation. Direct mid-sagittal views were obtained by either the transabdominal or/and the transvaginal approach. 3D reconstructed mid-sagittal views were obtained by either 3D multi:planar manipulations or VCI-C. The CC length was measured in direct mid-sagittal views and in 3D reconstructed mid-sagittal views. Results One hundred and thirty ultrasound examinations were performed. In 118 cases (91%) it was possible to obtain both a direct and a 3D reconstructed mid-sagittal view. Measurements of the CC length in direct mid-sagittal views correlated significantly with the measurements in reconstructed mid-sagittal views when the region underneath the comma-shaped echogenic structure was measured, but correlated poorly when this echogenic structure was included. Conclusions Reconstructed mid-sagittal views obtained by 3D multiplanar manipulations or by VCI-C are valid approaches for measuring CC length. In these views the CC should be measured as the region underneath the comma-shaped echogenic structure. Copyright (C) 2011 John Wiley & Sons, Ltd.
