Ultrasound How the Test is Performed:
The test is done in the ultrasound or radiology department. You will be lying down. A conducting paste is applied to the area to help with the transmission. The transducer (a hand-held instrument) is then moved over the area under investigation. You may be asked to move to other positions to examine different areas.

This is a normal fetal ultrasound performed at 17 weeks gestation. The development of the brain and nervous system begins early in fetal development. During an ultrasound, the technician usually looks for the presence of brain ventricles. Ventricles are spaces in the brain that are filled with fluid. In this early ultrasound, the ventricles can be seen as light lines extending through the skull, seen in the upper right side of the image. The cross hair is pointing to the front of the skull, and directly to the right, the lines of the ventricles are visible.
