[Visualization of the pancreas in the prone position with an automated water-coupled multisector scanner (Octoson)].
In a comparative study involving 300 patients the pancreas was demonstrated using the Combison 100 real-time system and the Combison 202 (compound-scanner) with the patients in supine position (without administration of methylcellulose or water) as well as with Octoson with the patient in the prone position. Both studies were performed within 1 hour in each case. Distribution of air in the abdomen is altered when the patient assumes the prone position for the Octoson study, a fact confirmed by 100 radiological examinations. This alteration in the distribution of air (in the abdomen) results in less interference when the pancreas is demonstrated. Other factors influencing visualization of the pancreas include: interposition of subcutaneous and omental fat (which cases absorption and defocussing of the ultrasonic beam) infiltrating of the pancreas by fat (lipomatosis) cutaneous scars, and hair, which disturbs contact between the transducer and the skin.
