title: [Initial results with the use of "contrast media", the so-called sonographica, for ultrasound examination of the upper abdomen].
abstract: First experiences with contrast media, so-called "sonographica", for the purpose to improve the ultrasonographic diagnostic of the upper abdomen are reported; special emulsions and suspensions with particle diameters between 50-2000 mu were used. The sonographica cause an echo texture similar to the liver and a more homogeneous ultrasonic absorption in the upper abdomen--within the range of frequencies and intensities used in sonographic diagnostic. This improves the possibility of obtaining cross-sections by using several transducers--arranged on a circuit--simultaneously. By increasing the echogenicity of the sonographicum the thickness of the stomach and duodenal wall can be indicated regularly for the first time.
