title: [Color coding in vascular Doppler echography aimed at improving lesion quantification].
abstract: Color flow duplex scanning diffusion is now restricted by an expansive cost. Static or dynamic range of a faint endovascular image can better be assessed by mean velocities. Pathologic high velocities allows visualisation of the direction and the width of the jet. The Doppler cursor can be correctly aligned in the jet core and allows accurate measures, and the display of spectral analysis is better with faster computers. Recently, enhancement of low flow analysis is of particular interest in pre-occlusive or occlusive vascular pathology.
