3D and 4D Fetal Neuroscan: Sharing the Know-how and Tricks of the Trade

Visual information from 2-D images may be limited in reflecting a 3-D structural reality. 3-D techniques have emerged enabling acquisition of an entire volume of spatial ultrasound information that can be analyzed and displayed in multiple planes and display modes that exceed the capacities of 2-D US and better reflect the 3-D nature of a structure or anomaly. In the future 3-D evaluation of the fetal body will be an inherent part of fetal study in cases of congenital anomaly' specifically fetal brain abnormality. This article focuses on the technique for obtaining and analyzing acquired volumes and displaying them.
