Abstract OBJECTIVE: To describe an easy technique for obtaining one of the most important views of the fetal brain and image. The entire lateral ventricle including the anterior, posterior and inferior horns is demonstrated on one image. We propose to call this view, obtained in an oblique plane 'the three horn view'. METHODS: Depending upon the scanning technique employed there are two ways to obtain the three horn view: (1) by two-dimensional (2D) transvaginal transfontanelle sonography obtained by using the left and right Oblique-1 sections, and (2) by three-dimensional (3D) imaging of the fetal brain, is obtained by acquiring a volume scan of the brain orienting the fetal head in the three main orthogonal planes and by rotating or tilting the midcoronal section to the left and right. RESULTS: To illustrate the technique of obtaining the three horn view four normal fetal brains were scanned. Two scans utilized the 2D transvaginal transfontanelle approach and two scans utilized the 3D scanning technique. The same technique was then applied to six fetuses with various brain malformations with inflicted changes in the shape of the proposed three horn view. CONCLUSION: The three horn view, depicting the anterior, posterior, and inferior horns on the same image, was easy to obtain using both the 2D and the 3D ultrasound techniques. It provided diagnostic and clinically useful information much like neonatal transfontanelle ultrasound imaging after which it was emulated.
