Duplex Sanning

A Duplex scanning is a procedure of tracking by ultrasound that demonstrates the structures in two dimensions and in real time. It shows the blood speed in two directions with a spectral analysis, of the flow in color and its speed. To perform a Duplex scanning it is necessary to perform a scanning in real time, therefore the billing of a duplex scanning and Doppler ultrasound of the same part of the body represents "unbundling" and does not proceed for payment. The Duplex scanning should be limited to specific indications. The information required is anatomically accurate. Therefore, the Duplex scanning must not be used for situations in which another diagnostic study is 0recommended. <a id="
