The 13th World Federation of Nuclear Medicine and Biology congress (WFNMB 2022): summarize the past half century and discuss the next half century of WFNMB-

The 13th World Federation of Nuclear Medicine and Biology congress (WFNMB 2022) was held in Kyoto and Kanazawa, Japan in September 2022, approximately half a century after the first World Congress of Nuclear Medicine held in Tokyo and Kyoto, Japan. In this paper, we describe the road to hosting another WFNMB congress in Japan, including the historic election for WFNMB 2022, the state of WFNMB 2022 in Kyoto, and the post-congress symposium in Kanazawa. This congress, themed “Summarize the past half century and discuss the next half century of WFNMB,” was successful and strongly encouraged doctors and researchers to develop future research and clinical practice in nuclear medicine.
