Abstract
With the advent and evolution of three-dimensional (3D) ultrasound technology over the last 15 years, we now stand at a new threshold in noninvasive diagnosis. The progression from two to three-dimensions has brought with it a variety of new options for imaging, storing and postprocessing of the ultrasound data. This technology gives ultrasound the multiplanar capabilities that were previously reserved for computed tomography and magnetic resonance imaging. Thanks to these imaging modalities it is possible to evaluate the finest anatomical details of the developing brain and spine and to increase the diagnostic accuracy when an abnormal sonographic finding of the fetal brain is recognized during the routine examination.
The amazing technology of 3D imaging enables the examination of the fetal central nervous system simultaneously in the three orthogonal planes, better defining the spatial relationship of CNS structures and malformations. The multiplanar mode is used to navigate through the volume, observing information on
