- Primary Outcome Measures
Name Time Method <p>The primary study parameter is qualitative re-staging after nCRT based on<br /><br>FDG-PET/MRI versus FDG-PET/CT, with pathology as gold standard (i.e.<br /><br>histopathologic assessment of the resection specimen when patients undergo<br /><br>surgery after nCRT, or histopathology/cytopathology of the primary tumor and<br /><br>suspected (distant) metastases as obtained during standard follow-up when<br /><br>patients do not undergo surgery or postpone surgery after nCRT).The other<br /><br>primary study parameters to assess feasibility include: experienced burden of<br /><br>undergoing FDG-PET/MRI, measurements of the primary tumor and lymph nodes,<br /><br>quantitative measurements of standardized uptake values at the primary tumor<br /><br>and suspected locoregional lymph nodes on FDG-PET/MRI compared to FDG-PET/CT,<br /><br>and quantitative measurements of the apparent diffusion coefficient at the<br /><br>primary tumor and suspected locoregional lymph nodes on FDG-PET/MRI.</p><br>
