Doppler-endosonography with the GF-UE 160 electronic radial echoendoscope - current use and future potential.

This tutorial survey with images examines current and possible future applications of the recently introduced 360-degree Doppler capable echoendoscopes. The better gray-scale resolution together with flow, spectral and color Doppler can improve EUS investigations in the mediastinum, abdomen and pelvis. There is no or very little EUS literature covering such important fields a Budd-Chiari syndrome, anatomic variations of the celiac trunk and hepatic artery, mesenteric artery flow determinations in the evaluation of mesenteric ischemia and arterial compression syndromes (celiac, superior mesenteric artery and hepatic artery). Additional other areas of possible future research are suggested.
