[Contrast-enhanced sonography of the abdomen and retroperitoneum].

Contrast-enhanced sonography is unquestionably the scientific highlight of any ultrasound congress at present. Recent results of studies on contrast media in the liver indicate that the diagnosis of tumours and metastases has reached the standard of CT and MRT and may even surpass it. The sessions dealing with contrast sonography in Graz are therefore a good indicator of the general enthusiasm and increasing acceptance for this technique and its prevalence. The talks delivered and the posters presented also point out difficulties in spreading this new technique and applying it to new indications.
