- W2079303732 abstract "The aim of this study was to evaluate the effect of ordered‐subset expectation maximization reconstruction algorithm with scatter correction and attenuation correction based on computed tomography maps and to find out the optimum number of subsets and iterations upon image quality for 123I−DaTSCAN neuroimaging. We retrospectively studied SPECT/CT scans of 44 consecutive patients with clinical indications of Parkinson’s disease. Images were reconstructed with use of two methods: filtered back projection and OSEM. Image quality was assessed by: striatal binding indices as a measure of contrast and coefficients of variation as a measure of noise. The quality of DaTSCAN images reconstructed with the use of OSEM (4iter/10subs) with reconstruction corrections was superior to that provided by the commonly applied FBP." @default.
