FOREWORD
Therapeutic radiopharmaceuticals play a major role in todays nuclear medicine, especially in the treatment of cancer. They have long been applied in radiation synovectomy, or, more briefly, radiosynovectomy (RSV) . In recent decades, the production and quality control of radiopharmaceuticals for use in RSV has moved from simple P colloids to recently developed matrixes labelled with short and medium range beta emitters. RSV is a well established technique with growing applications worldwide. However, the lack of generic and peer reviewed production, quality control and clinical application guidelines and recommendations is a major concern for their application in human patients.
Given both the IAEAs global efforts in supporting Member States in the application of nuclear techniques in radiopharmacy and health and several requests from Member States as well as professional societies in recent years, the need for an IAEA technical publication on the subject became apparent. Currently, there is a lack of international standardized regulations for RSV production and clinical use. This publication is intended for professionals in the field. It outlines ideal quality control and quality assurance procedures in the production of several radiopharmaceuticals for performing RSV, as well as the standard operating procedures needed to achieve successful therapeutic effec ts in patients.
This publication is the outcome of the continuous efforts of an international expert team that was in the field between 2016 and 2018; the IAEA wishes to thank the experts for their valuable work and scientific contribution, especially A. Dash (India) and J. Farahati (Germany). Special thanks to J.S. Vera Araujo from the Division of Physical and Chemical Sciences for her support in revising and editing. The IAEA officers responsible for this publication were A.R. Jalilian and F. Giammarile of the Division of Physical and Chem ical Sciences.

1. INTRODUCTION
1.1.Background
Radiopharmaceuticals have had an incrementally positive impact in the health sector since the 1950s, especially in the diagnosis and treatment of diseases. In particular, radiation synovectomy, known more briefly as radiosynovectomy (RSV), has been used as an alternative minimally invasive treatment for joint inflammation. A common manifestation of this is rheumatoid arthritis, which, despite recent therapeutic advances, remains incurable. RSV has been used for over 50 years as an adjunct to conventional treatment (e.g. corticosteroids, arthroscopic synovectomy, arthrodesis) of refractory painful and disabling synovitis in patients with rheumatoid arthritis and other inflammatory synoviopathies, such as activated osteoarthritis and haemophilia. RSV is a local treatment with ionizing radiation involving the coupling of the right unsealed beta emitting radioisotope with a suitable colloid applied intra-articularly to irradiate the pathological superficial synovial membrane. A multidisciplinary approach involving rheumatologists, orthopaedists and nuclear medicine physicians, as well as a good understanding of the pathophysiology of synoviopathy, are essential for selecting the most appropriate treatment for individualized joints in order to optimize the result of this minimally invasive local therapy. Hence, RSV production and application ought to be handled and administered carefully, as there are several requirements to meet to deliver succes sful outcomes.
