Zusammenfassung
Introduction: FDG-PET and PET/CT is increasingly used for radiotherapy (RT) planning in non-small-cell lung carcinoma (NSCLC). The RT planning process is often based on separately acquired FDG-PET/CT and planning CT. The influence of the fusion of PET data with CT data acquired with different breathing manouvers and different PET-data acquisitions on FDG-based groß tumor volume (P-GTV) definition is not known to date. We compared intra- and interindividual differences of P-GTV between PETs acquired in diagnostic and RT position coregistered with planning CTs acquired during different breathing manouvers. Materia…
