AIM: Ultrasound angiography is a new method of colour-coded vessel imaging. The present study aimed at giving further information on its clinical utility in neurosonology.
METHOD: The extracranial arteries of 53 patients and 5 normal persons were investigated by ultrasound angiography in comparison with colour-coded duplex sonography.
RESULTS: We found a sharper imaging of stenoses and plaques by ultrasound angiography compared with colour Doppler. The imaging of the vessels can be achieved more continuously, avoiding dropouts of the colour. Small vessels and branches can be detected more reality.
CONCLUSION: Ultrasound angiography represents a valuable additional imaging technique to colour-coded duplex sonography, providing further information, especially with regard to the border of plaques and stenoses.
