First experience with ultrasound angiography of extracranial and peripheral arteries in 20 patients is reported. Ultrasound angiography is a new method of color-coded vessel imaging. It is based on signal processing of the blood flow amplitudes. Color imaging of echo signals by ultrasound angiography is independent of the direction and velocity of blood flow and of the angle of ultrasound beam. Aliasing and changes of colors due to changes of direction do not exist. We found a sharper imaging of the vessel lumen and the vessel wall compared with color Doppler. Imaging of vessel branches and small vessels is even better. Documentation of vessels by ultrasound angiography is similar to angiography and can be obtained convincingly. Application of this method in addition to color-coded duplex sonography is recommended.
本文报道了对20例患者进行颅外和外周动脉超声血管造影的首次经验。超声血管造影是一种彩色编码血管成像的新方法。它基于血流振幅的信号处理。超声血管造影对回波信号的彩色成像与血流方向、速度以及超声束角度无关。不存在因方向改变而导致的混叠和颜色变化。与彩色多普勒相比，我们发现血管腔和血管壁的成像更清晰。血管分支和小血管的成像甚至更好。超声血管造影对血管的记录与血管造影相似，且能令人信服地获得。建议在彩色编码双功超声检查之外应用此方法。
