PET has the invaluable advantage of being intrinsically quantitative, enabling accurate
measurements of tracer concentrations in vivo. In PET tumor imaging, indices characterizing …

Abstract Positron Emission Tomography (PET), a non-invasive functional imaging method at
the molecular level, images the distribution of biologically targeted radiotracers with high …

Purpose The purpose of this educational report is to provide an overview of the present state‐
of‐the‐art PET auto‐segmentation (PET‐AS) algorithms and their respective validation, with …

Purpose A new gradient-based method for segmenting FDG-PET images is described and
validated. Methods The proposed method relies on the watershed transform and …

Malignant tumors with high glucose metabolic rates accumulate [18F]–fluorodeoxyglucose
(FDG), a positron emitting tracer. The aim of this study was to evaluate FDG positron …

In the early days of PET, the partial volume effect (PVE) was identified as a serious factor
affecting image quality and limiting the accuracy of quantitative analysis. Because of the …

Partial-volume errors (PVEs) in PET can cause incorrect estimation of radiopharmaceutical
uptake in small tumors. An iterative postreconstruction method was evaluated that corrects …

Objectives Correction of the “partial volume effect” has been an area of great interest in the
recent times in quantitative PET imaging and has been mainly studied with count recovery …

In 18F-FDG PET, tumors are often characterized by their metabolically active volume and
standardized uptake value (SUV). However, many approaches have been proposed to …

PET imaging of metabolism involves many choices, from hardware settings, software options
to animal handling considerations. How to decide what settings or conditions to use is not …
