Comparison of the size (mean, SD) of the lymph node metastases detected or not on the 18FDG PET/CT scans at each acquisition duration time from 2 to 10 min depending on the reconstruction modality in surgical patients. OSEM-/PSF- are lesions not detected by either reconstruction, OSEM-/PSF+ are those detected only by PSFallpass reconstruction, and OSEM+/PSF+ are those detected by both reconstructions
