International Symposium on Trends in Radiopharmaceuticals (ISTR-2023)

17–21 April 2023, Vienna, Austria

Trends in Radiopharmaceuticals (ISTR-2023)


Advances in nuclear medicine have opened possibilities to generate unprecedented solutions to clinical problems by providing better diagnosis and more efficient therapies. Emerging new radiopharmaceuticals and efficient production of relevant radioisotopes have been always tightly linked to these developments.

Impressive technologies including high-energy and high-current accelerators are now becoming available for radioisotope production in addition to the existing ones. This has allowed broader access to several promising radionuclides, including gallium-68, copper-64 and zirconium-89. Development of high-power electron linacs resulted in the production of therapeutic radionuclides such as scandium-47, actinium-225, and copper-67. Alternative methods, using both electron and proton accelerators, are being developed for large scale production of molybdenum-99/technetium-99m, which remains the most widely used diagnostic radionuclide. Read more →

Purpose and Objectives

The International Symposium on Trends in Radiopharmaceuticals, ISTR-2023, will provide scientists and other professionals working in the production of radioisotopes and radiopharmaceuticals with an international forum to discuss the most recent developments and challenges in the field. Topics covered during the event, including the development, production and uses of diagnostic, therapeutic and theranostic radioisotopes and radiopharmaceuticals, as well as regulatory and licensing issues. Education, certification and training methodologies will also be addressed. We expect participants from academia, industry, healthcare institutions, regulatory bodies and other organizations. Read more →

Target Audience

The target audience for this Symposium includes (radio)chemists, (radio)pharmacists, biologists, physicists, technologists, medical researchers, policy makers and health regulators, educators and other professionals working in the fields of production and uses of medical radioisotopes and radiopharmaceuticals. The IAEA welcomes and encourages the participation of individuals from developing countries, women, and early career professionals including students.

Key Deadlines and Dates

  • 30 September 31 October 2022: Submission of abstracts through IAEA-INDICO
  • 30 September 31 October 2022: Submission of Form B (together with Form A) through the InTouch+ platform
  • 30 September 31 October 2022: Submission of Form C (together with Form A) through the InTouch+ platform
  • 30 November 2022: Notification of acceptance of abstracts for oral or poster presentation
  • No deadline: Submission of Form A only (no paper submission, no grant request) through the InTouch+ platform


To demonstrate its commitment to sustainability, the IAEA will organize this conference as a 'green meeting' according to the guidelines of the Austrian Ecolabel.

There will be a focus on the areas of paper smart documentation, waste reduction and recycling, and environmentally friendly catering.

Conference app

The IAEA Conferences and Meetings App provides a one-stop access to information on the Conference, exhibitions and scheduled side events. The app also allows users to put together their own personalized schedule of events. Via this app participants will be able to view contributed papers and the latest conference programme, message other participants, and view PowerPoint presentations released after the event. Participants will receive an email inviting them to register for the app approximately one week before the conference.

For iPhone or iPad users, get your free download through the App Store; those with Android devices can visit the Google Play Store.
