WORK IN PROGRESS CAVUS - TRANSCAVAL ULTRASONOGRAPHY OF ABDOMINAL ORGANS - PRELIMINARY-RESULTS

Endoluminal sonography using tiny transducers (20 MHz) has found wide application in various fields of investigation. We have applied the sa me technology to the assessment of abdominal organs using the transcav al route (CAVUS). Normal vessels and both normal and dilated bile duct s were displayed. Although the procedure is simple and safe, and the i mages produced are excellent, to be useful clinically, microtransducer s (6 or 7 MHz) will have to be developed. This technique holds much pr omise, and further miniaturization will allow greatly expanded use of endoluminal approaches.
