Nuclear medicine has a central role in the diagnosis, staging, response assessment and long-term follow-up of neuroblastoma, the most common solid extracranial tumour in children. These EANM guidelines include updated information on I-mIBG, the most common study in nuclear medicine for the evaluation of neuroblastoma, and on PET/CT imaging withF-FDG, F-DOPA andGa-DOTA peptides. These PET/CT studies are increasingly employed in clinical practice. Indications, advantages and limitations are presented along with recommendations on study protocols, interpretation of findings and reporting results.
Highlights d Pathologic protein networks and their engagement in clinic are monitored by imaging d Real-time tumor pharmacometric data are obtained at the level of individual tumors d Theranostic and clinical assay combined provide quantitative tumor measurements d The platform provides dose and schedule information for epichaperome targeting
Background: To fulfil good manufacturing requirements, analytical methods for the analysis of pharmaceuticals for human and vetinary use must be validated. The International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) has published guidance documents on the requirements for such validation activities and these have been adopted by the European Medicines Agency, The U.S. Food and Drug Administration (FDA) and other regulatory bodies. These guidance documents do not, however, fully address all the specific tests required for the analysis of radiopharmaceuticals. This guideline attempts to rectify this shortcoming, by recommending approaches to validate such methods. Results: Recommedations for the validation of analytical methods which are specific for radiopharmaceutials are presented in this guideline, along with two practical examples. Conclusions: In order to comply with good manufacturing practice, analytical methods for radiopharmaceuticals for human use should be validated.
This guideline on current good radiopharmacy practice (cGRPP) for small-scale preparation of radiopharmaceuticals represents the view of the Radiopharmacy Committee of the European Association of Nuclear Medicine (EANM). The guideline is laid out in the format of the EU Good Manufacturing Practice (GMP) guidelines as defined in EudraLex volume 4. It is intended for non-commercial sites such as hospital radiopharmacies, nuclear medicine departments, research PET centres and in general any healthcare establishments. In the first section, general aspects which are applicable to all levels of operations are discussed. The second section discusses the preparation of small-scale radiopharmaceuticals (SSRP) using licensed generators and kits. Finally, the third section goes into the more complex preparation of SSRP from non-licensed starting materials, often requiring a purification step and sterile filtration. The intention is that the guideline will assist radiopharmacies in the preparation of diagnostic and therapeutic SSRP’s safe for human administration.
Tellurium dioxide / Iodine-124 / Dry distillation / PET Summary. Iodine-124 is a radionuclide with a 4.18 day halflife which decays by positron emission (23.3%) and electron capture (76.7 %). Details on the preparation of this radionuclide via the 124 Te(p,n) 124 I nuclear reaction are described. A reusable target uniquely suited for low energy cyclotron irradiations has been described along with specific characteristics for the dry distillation recovery of the 124 I species.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
