[Ultrasound in oncology, current perspectives].

In tumor diagnostics, especially in the staging diagnostic of tumor patients, ultrasound is predominantly an additive method in the age of modern imaging (CT/MRT/PET-CT), because of the limitation by interobserver variability and poor sound conditions. The aim of this thesis is to elaborate specific oncological questions on the sonography and to describe the requirements for sonography and the importance of the method in the diagnosis of tumor diseases in the age of CT, MRT and PET-CT. In general, the requirements on the sonography must be differentiated between primary diagnosis, staging diagnostic, treatment response, and tumor aftercare. This paper will present these in the context of the current guidelines of the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) and the Working Community of the Scientific Medical Societies as well as the requirements in clinical practice.
