Two\u2010dimensional (2D) transvaginal sonography was an important step in understanding the constantly changing and developing fetal brain. The objective of this article is to describe the use of three\u2010dimensional ultrasound of the fetal brain enhanced by the transvaginal transfontanelle scanning technique.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Thirty\u2010four pregnant patients were referred to us because of a history of brain anomaly or suspected brain pathology. The fetuses were scanned transvaginally. Two\u2010dimensional as well as three\u2010dimensional (3D) images were generated. The volumes obtained by the 3D\u2010ultrasound machine were displayed in the three conventional orthogonal planes (coronal, sagittal and axial).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the 34 fetuses 10 had normal brain anatomy and 24 had brain pathology. In all 34 cases the 2D images as well as the 3D volumes were of diagnostic quality and all three planes could be obtained. The axial sections could only be obtained by the 3D re\u2010construction of the volume scans. The 2D images produced were acquired from a common point originating from the foot print of the transvaginal probe at the fetal anterior fontanelle or the sagittal suture, the sections \u2018radiate\u2019 from this point. Therefore, these sections are not parallel sections, but are oblique to each other. In contrast, the 3D volume could be examined using the classical parallel sections in all three orthogonal planes. The posterior fossa could be seen better if the footprint of the probe was placed over the posterior fontanelle or on the sagittal suture. The marker dot enabled a precise creation of anatomy and pathology. In the \u2018angio mode\u2019 it was possible to follow the anterior cerebral and pericallosal artery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The 3D\u2010ultrasound technology using the transvaginal approach is effective and practical to perform during fetal neuroscan. The ability to \u2018navigate\u2019 in the volume and the \u2018marker dot\u2019 enables exact location of normal structures and evaluation fetal brain pathology. The volume can be reviewed over and over again, can be mailed to an expert, could be shown to consultants (pediatric neurology and neurosurgeons) and used for teaching.
