[Doppler ultrasonic arteriography with colorimetric morpho-function analysis of frequency (Echoflow). Preliminary trials].
Doppler arteriography with chromatic frequency analysis is a new and very sound diagnostic method in cases of vascular disease. It can be carried out with apparatus such as the Echoflow (reg'd), a natural development of the Doppler technique ultrasonography. Vessels are shown in red, yellow, or blue, depending on the rate of their intraluminal flow. Surface arteries lying 5-6 cm below the skin and not hidden by bone can be studied. Preliminary results on 23 supra-aortic trunks, 21 lower extremity arterial systems, and 5 upper limb systems are described. The use of the instrument in other situations in also recommended.
