Echocolor Doppler Physics and How To Do It

In biology the Doppler effect allows to distinguish a laminar flow (present in normal artery) from a pathological one with increased velocity or reversal flow (present in a stenotic artery).

The echocolor Doppler is the integration of information: 1) B-mode (gray scale image); 2) color (blood flow images are superimposed to the B-mode images); 3) Doppler (to obtain hemodynamic information).

These ultrasound integrated informations allow to explore reliably and noninvasively all the vascular districts; in recent years, in particular, they have played a very important role in changing the attitude of clinicians towards important vascular diseases such as atherosclerosis and venous thrombosis of the lower limbs.

In these lessons the echocolor Doppler physics and the technique of execution of the ultrasound study of the extra-and intracranial vessels, of the aorta and the arteries of the lower limbs are presented.
