Abstract
Patient noise equivalent count (NEC), NEC density, and liver region of interest (ROI) S/N have been proposed as physical indicators of image quality, but have not been thoroughly compared with visual assessments. In this study, those indicators were contrasted with blind visual evaluations for whole-body fluorodeoxyglucose–positron emission tomography (FDG-PET) images acquired under a variety of scanning conditions and body weights. Images were...
