Brief summary
The comparison of the imaging with 2D, 3D and 4D VCI-C ultrasound methods for the fetal midbrain and posterior fossa structures. These structures include corpus callosum, brainstem-tentorium angle, brainstem-vermis angle, cerebellar fissures and vermis.
Interventions
The evaluation of fetal midbrain and posterior fossa stuctures with ultrasound after their second trimester fetal anatomic survey is done. The ultrasound evaluation will be done using 2D, 3D and 4D modalities. Fetal intracranial structures(midbrain and posterior fossa structures) will be the point of interest. It will be done only once and will take approximately 20 min.The 3D and 4D VCI-C ultrasound methods are the intervention methods studied in this trial. 3D is a record of the image in three dimensions whereas 4D VCI-C is a real time evaluation of these dimensions.
