Figure 7. FAST Echo algorithm and Volume Contrast Imaging (VCI) applied to a normal fetus at 26 weeks of gestation.

Figure 7

All three independent planes are simultaneously visualized (along with the longitudinal view of the ductal arch/pulmonary artery) after placement of 3 lines. VCI has been activated with a slice thickness of 2 mm and X-ray/surface smooth (Mix 100/0%) render mode applied. VCI allows images to appear smoother and the interface between different tissues to be more apparent. The render direction applies from the solid to the dotted line.
