Because of the current progress in molecular medicine (genomics, proteomics), a plethora of new and often human-specific targets are being identified. These targets often play a significant role in the pathogenesis of diseases, and identifying them offers the potential for early diagnosis and intervention. An early in vivo validation of specific ligands binding to these targets in humans is needed to as sess their potential for targeted imaging and radiotherapy. Further- VI Preface more, such validation studies may allow for a better understanding of the molecular processes underlying...

Das diesjahrige Forum wurde aus einer ahnlich groBen Anzahl von Anmeldungen zusammengestellt wie in den vergangenen Jahren. Knapp ein Drittel der Abstracts konnte vom Wissenschaftlichen Beirat nach anonymer Begutachtung angenommen werden. Annahmegrlinde waren wie in den vergangenen Jahren besondere Originalitat, fehlende Vorwegpublikation, sorgfaltige Abfassung des Abstracts, hohe klinische Relevanz und nicht zuletzt auch einwandfreie formale und inhaltliche Beschreibung. Die Schwergewichte haben sich weiterhin zugunsten der chirurgi schen Onkologie und des Gebietes "Leber, Galle, Pankreas"...

New developments in the field of high resolution imaging focus on functional parameters pertaining to disease-specific medical imaging. Such new diagnostic strategies are possible using scintigraphic techniques and, more recently, by MRI and US. In addition, new therapeutic concepts, including gene therapy, require specific tracers or contrast media for therapy monitoring, for example, enzyme activity and changes in receptor expression. For this purpose scientists conducting basic research, expecially molecular biologists, and clinicians must collaborate in order to exploit the available...
