Abstract
The joint study among 9 national hospitals was performed in order to establish early diagnostic system by nuclear medicine during the period from 1979 to 1981.
Recent progress in clinical nuclear medicine and development in instrumentation and radiopharmaceuticals are closely linked. Members of this study group had specialized field and it was necessary to have explosively increasing knowledge in related fields, such as biochemistry, biophysics and biomedical engineering. This required an ability to learn advanced technology other than medicine. During these 3 years we have tried to keep this in mind and have attempted to publish a monograph compiled in a single volume to present outstanding works. This basic cóncept supported the purpose of our group studies to provide broad insight into this subject.
Significant development has been made in the areas of both in vivo and in vitro nuclear medicine in our joint study group. However, some papers may be imcomplete because of a rapidly expanding knowledge. These problems may be filled in part by progress of current investigation.
