From: Impact of penalizing factor in a block-sequential regularized expectation maximization reconstruction algorithm for 18F-fluorocholine PET-CT regarding image quality and interpretation

  1. Image quality in pilot study. Image quality in 18F-FCH PET-CT examinations (graded 1–5 where 1 = unacceptable image quality and 5 = very high image quality) for the three patients in the pilot study for all combinations of β and frame duration as well OSEM. The combinations shown in grey were further evaluated regarding image quality and lymph node metastases
