Optimization of iterative reconstruction parameters with 3-dimensional resolution recovery, scatter and attenuation correction in 123I-FP-CIT SPECT

Objective The aim of this study was to determine the optimal reconstruction parameters on ordered-subset expectation maximization iterative reconstruction with resolution recovery, scatter and attenuation correction (OSEMRRSCAC) on 123I-FP-CIT SPECT in terms of the image quality, quantification and diagnostic ability.
