Triplex Ultrasound (Color-Flow Imaging)
Triplex Ultrasound (Color-Flow Imaging)
Color-flow imaging (also called triplex ultrasound) is an enhanced form of Doppler ultrasound technology. In a procedure similar to duplex ultrasound, it uses color to highlight the direction of blood flow. Vessels in which blood is flowing are colored red for flow in one direction and blue for flow in the other, with a color scale that reflects the speed of the flow.
Because different colors are used to designate the direction of blood flow, this Doppler technique simplifies interpretation of the ultrasound data.
