11C-labeled neuroreceptor ligands frequently require long scan durations to quantify ligand-receptor binding. In this paper, we compare the accuracy of two three-dimensional (3D) positron emission tomography (PET) reconstructions: ordered-subset expectation-maximization (OS-EM) versus filtered backprojection (FBP) under low count rate conditions exhibited by 11C neuroreceptor studies. Data were obtained from a dynamic 11C phantom acquisition as well as six dynamic human [11C] WAY-100635 studies… CONTINUE READING
