Partial-Volume Correction in PET: Validation of an Iterative Postreconstruction Method with Phantom and Patient Data

Partial-volume errors (PVEs) in PET can cause incorrect estimation of radiopharmaceutical uptake in small tumors. An iterative postreconstruction method was evaluated that corrects for PVEs without a priori knowledge of tumor size or background. Volumes of interest (VOIs) were drawn on uncorrected P...
