title: [Improvement in abdominal imaging in sonography by the compression and compound technics].
abstract: In a clinical study with 663 patients the influence of compression and compound technique of the visualisation of the abdomen was tested with a real-time-scanner Combison 100, compound scanner Combison 202 and the Octoson-machine. In 66 patients the retroperitoneal space was not demonstrated. Compression with the real-time-transducer improves demonstration in 50% (33/66), compound-technique 20% (19/66). Compound-technique was handicapped in 30% (19/66) by velocity errors and reflection which causes a deterioration in resolution.
