In-utero three-dimensional magnetic resonance imaging of fetal brains

We assessed ten prenatal magnetic resonance imaging (MRI) scans for fetal brain anomalies, and identified eight that were suitable for post-processing. Anatomical abnormalities were assessed on the three-dimensional (3D) models and compared with two-dimensional (2D) imaging findings. We calculated the volume of the intracranial ventricles and a periventricular haemorrhage. In three cases additional clinical information was obtained. 3D modelling of the brain in-utero is possible and can be used to plantreatment. Additional information provided by in-utero MRI facilitated postnatal management of a vein of Galen malformation.
