Transversal 68Ga-DOTATOC PET images of a patient with small intestinal neuroendocrine metastases. Images were acquired 72 min post-injection and reconstructed with 2 min/bp using OSEM (3 iterations, 16 subsets, 5-mm Gaussian post-processing filter) and BSREM with β-values of 133, 267, 400, and 533. Both reconstruction methods included TOF and PSF recovery. The administered activity was 1.8 MBqkg−1. The SUVmax of the lesion (arrow) is shown for the respective reconstruction
