Study Summary
The purpose of this study is to assess the effectiveness of new software available on a new PET/CT scanner in the Molecular Imaging Research PET/CT Facility. Further, the study aims to evaluate the data acquisition and image processing workflow.
Primary Outcome
Confirm that motion-corrected reconstructed images acquired when the subject was moving provides similar image quality to the baseline reference reconstructed images acquired when the subject was instructed to remain still. For each subject compute the cumulative absolute relative difference (ARD) histogram in standard uptake values in grey matter voxels in images with and without motion correction versus a reference image for which the subject was stationary, then calculate the percentage of vo
Interventions
