From: Significant artefactual noise in 90Y TOF-PET imaging of low specific activity phantoms arises despite increased acquisition time

a, b 18F and 90Y hot rod sector slices obtained using specific activities and acquisition times similar to that of clinical whole-body 18F-FDG and of post 90Y liver radioembolization, respectively. c, d 90Y hot rod sector slices obtained using lower specific activities compensated by longer acquisition times, and additionally in d by slice summation, in order to get the same number of detected coincidences per millilitre
