EXTENDED DIAGNOSTICS OF COLOR-CODED DUPLEX SONOGRAPHY BY MEANS OF ULTRASOUND CONTRAST AGENTS - IMAGING OF MOVEMENTS IN THE URINARY-TRACT AND TUBAE BY ANIMAL-EXPERIMENT

In colour-coded Duplex sonography, ultrasound contrast agents produce a significant enhancement of Doppler signals from the blood. Animal experiments were performed to examine whether a combination of colour-coded Duplex sonography and ultrasound contrast agents can also visualise movements from hollow spaces which do not normally contain scatteres (or an insufficient number of them). The animal experiments showed that the method can visualise both movements in the tubae and a vesicoureteral reflux. This opens up new diagnostic possibilities for ultrasound, which, however, still require rechecking by means of clinical studies.
