Summary
Brief summary (as posted)
The aim of this study is to examine if late FDG-PET/CT images after intravenous FDG injection has a higher sensitivity and specificity in detecting local lymph node metastases in patients with muscle invasive BC than FDG-PET/CT images 60 minutes after FDG injection. The latter procedure has been used routinely until now.

Inclusion criteria: * Patients diagnosed with BC who are candidates for cystectomy and undergo cystectomy with lymph node dissection or have a needle biopsy of at least one FDG-PET/CT local lymph node suspected for malignancy following the FDG-PET/CT due to their BC. Exclusion criteria: * Patients who have received chemotherapy, including neoadjuvant chemotherapy, in the timespan between the FDG-PET/CT and the needle biopsy or the lymph node dissection.
