[Procedural guideline for Iodine-131 whole-body scintigraphy in differentiated thyroid carcinoma (version 5)].

Version 5 of the procedural guideline for Iodine-131 whole-body scintigraphy (WBS) in differentiated thyroid carcinoma is an update of the version 4, published by the "Deutsche Gesellschaft für Nuklearmedizin" (DGN). This procedural guideline advises on how to best perform I-131 whole body scintigraphy after I-131 therapy or after application of a diagnostic I-131 activity. A representative expert group has discussed and reached consensus on the procedural guideline; the development of this procedural guideline therefore fulfils the criteria for level S1 (first step) within the classification of the German Workgroup of Scientific Medical Societies ("Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften"; AWMF).
