Once again, the proceedings of the Badgastein Symposium, this one being the 22nd in an uninterrupted series, offer a comprehensive record of the scientific events. Highlights at this meeting were certainly reports ofthe exciting new developments ofpositron imaging with Anger cameras, both with conventional high-energy collimators and with coincidence techniques. Preliminary c1inical results are promising and seem to offer a true alternative to sophisticated PET -technology with its for many laboratories prohibitive costs. The general nature ofthe symposium is documented by the large range oftopics covered so that all major topics of interest in both the basic sciences of nuc1ear medicine and c1inical ap plication are found. In accordance with the general trends in nuc1ear medicine, there has been a substantial increase in oncological work compared to the more traditional topics. This is also reflected in the Badgastein lecture, given by Professor P. Rigo, who presented an excellent survey ofnuc1ear oncology.
