The aim of this study was to investigate the effects of the point-spread function (PSF) and
time-of-flight (TOF) on improving 18 F-FDG PET/CT images in relation to reconstruction …

Purpose The purpose of this study was to investigate the effects of point-spread function (PSF)
and time-of-flight (TOF) on the standardized uptake value (SUV) of lymph node metastasis …

Brain PET, which has led research in molecular imaging and diagnosis of brain cancer,
epilepsy and neurodegenerative disorders, is being spotlighted again to promote earlier …

Parallax error caused by the detector crystal thickness degrades spatial resolution at the
peripheral regions of the field-of-view (FOV) of a scanner. To resolve this issue, depth-of-…

Standardized uptake values (SUVs) have been widely used in the diagnosis of malignant
tumors and in clinical trials of tumor therapies as semiquantitative metrics of tumor 18 F-FDG …

PET can reveal in vivo biological processes at the molecular level. PET-derived quantitative
values have been used as a surrogate marker for clinical decision-making in numerous …

Objective. For PET imaging systems, a smaller detector ring enables less intrinsic spatial
resolution loss due to the photon non-collinearity effect as well as better balance between …

Positron emission tomography (PET) plays an increasingly important role in research and
clinical applications, catalysed by remarkable technical advances and a growing appreciation …

The aim of this study was to evaluate the imaging performance of 39- and 52-ring time-of-flight
(TOF) PET/CT scanners. We also assessed the potential of reducing the scanning time …

Objective The aim of this study was to evaluate the effect of the point spread function (PSF)
and time of flight (TOF) on PET/CT images of overweight patients in relation to the iteration …
