[Angiodynography: technical principles and clinical uses].
Angiodynography is a newly developed system that enables Doppler sonography to be used to obtain a colour-coded real-time image of the blood vessels in the familiar ultrasound slice image. A new computerised technique allows both the familiar pulse echo signal and the Doppler shift of the signal resulting from movement in the body to be displayed for each point on the ultrasound slice plane. Stationary tissue structures are shown as the familiar grey scale image, while movement such as of the blood is shown in colour. 453 patients were examined. Normal and pathological flow measurements were obtained in the carotid artery, the jugular vein, in renal transplants, in the thyroid, the testis and in the urethra. Pathological flow velocities were visualised in stenosis, tumours and diffuse alterations of parenchyma.
