Combination of B-mode sonography (imaging sonography) and Doppler method. Using duplex sonography, both a 2-dimensional sectional image and the flow curve of the examined vessel can be displayed. By means of colour coding, the blood flows in the vessels can be displayed in colour according to their flow direction.

The addition "Duplex" means that 2 signals can be supplied and processed simultaneously. Firstly, the sonographic image (B-mode) shows an image of the blood vessel. Using the Doppler method, the flow velocity of the blood in the examined vessel can be measured simultaneously.

Duplex sonography is used to examine the heart and the different vascular areas of the most diverse organs.
