Accurate quantification in PET and SPECT requires correction for a number of physical
factors, such as photon attenuation, Compton scattering and random coincidences (in PET) …

Partial volume effects in positron emission tomography (PET) lead to quantitative under-and
over-estimations of the regional concentrations of radioactivity in reconstructed images and …

Partial volume effects (PVEs) are consequences of the limited spatial resolution in emission
tomography. They lead to a loss of signal in tissues of size similar to the point spread …

Correction for Partial Volume Effects in PET: Principle and Validation Page 1 Correction for
Partial Volume Effects in PET: Principle and Validation Olivier G. Roussel, Yilong Ma and Alan …

Positron emission tomography (PET) images are degraded by a phenomenon known as the
partial volume effect (PVE). Approaches have been developed to reduce PVEs, typically …

Despite the continuous evolution of positron emission tomography (PET) technology, the
spatial resolution (SR) of PET images remains poor (4–6 mm) compared with that of …

Partial volume (PV) effects degrade the quantitative accuracy of SPECT brain images. In this
paper, we extended a PV compensation (PVC) method originally developed for brain PET …

Abstract Purpose Partial volume effects (PVEs) are consequences of the limited resolution of
emission tomography. The aim of the present study was to compare two new voxel-wise …

Correcting positron emission tomography (PET) images for the partial volume effect (PVE)
due to the limited resolution of PET has been a long-standing challenge. Various …

PET imaging of D2 receptors or 18F-l-dopa metabolism are reference protocols to follow and
study neurodegenerative diseases, but the accuracy of striatal PET imaging is limited by the …
