466 Objectives Resolution modeling is known to improve quantification in small structures
by reducing the partial-volume effects. The aim of this work is to assess the impact of a fast …

1836 Objectives The finite resolution of PET results in partial volume effects (PVE). PVE
correction is a requisite for improvement of PET quantification of small structures. The aim of …

577 Objectives In this study we compare an OSEM algorithm incorporating measured point
spread functions (PSF) modeling for resolution recovery, and two post-reconstruction …

1459 Introduction: Modern PET/CT with better instrumentation and software could possibly
produce more accurate diagnosis for brain studies such as in Alzheimer disease. The …

2341 Objectives Point spread function (PSF) based image reconstruction increases
apparent spatial resolution at the expense of possible edge artifacts. Our aim was to …

1930 Objectives Several methods to correct partial volume effect (PVE), based on magnetic
resonance (MR) images, have been proposed and utilized widely in PET studies. However …

2041 Objectives Partial volume correction (PVC) is necessary in brain PET studies to
differentiate an artefactual reduction in radiotracer uptake due to cerebral atrophy from a true …

The benefit of partial volume correction (PVC) within and post image reconstruction for high
resolution PET scanners was examined. Listmode data from a realistic simulation of the …

Background Accurate quantification of PET studies depends on the spatial resolution of the
PET data. The commonly limited PET resolution results in partial volume effects (PVE) …

Objective In quantitative positron emission tomography (PET) of the brain, partial volume
effect due mainly to the finite spatial resolution of the PET scanner (> 3 mm full width at half …
