Respiratory motion causes a spread of lesion uptake over a larger area in Positron Emission
Tomography (PET) images for moving structures. When CT images are used for attenuation …

Purpose We applied deviceless, positron emission tomography/computed tomography
(PET/CT) data-driven respiratory gating (DDG) to validate the effects of misalignment …

In many ways, the lung is an ideal organ for study with positron emission tomography (PET).
First, structure-function relations are homogeneous over larger areas than in other organs …

Respiratory motion is known to affect the quality of PET imaging of the thorax and abdomen,
hindering the localization, detection of the lesions, and quantification of tracer uptake in a …

233 Objectives Our aim is to investigate the impact of respiratory motion on tumor
quantification and delineation in wholebody (WB) PET/CT imaging using a population of …

Positron emission tomography (PET) provides three-dimensional images of the distributions
of radionuclides that have been inhaled or injected into the lungs. By using radionuclides …

Abstract Objectives MotionFree®(AMF) is a data-driven respiratory gating (DDG) algorithm
for image processing that has recently been introduced into clinical practice. The present …

Background In thoracic PET/computed tomography (CT) imaging, uptake foci usually appear
smeared because of postreconstruction smoothing and respiratory motion. Objective The …

Previous literature has shown that 4D respiratory-gated positron emission tomography (PET)
is beneficial for quantitative analysis and defining targets for boosting therapy. However the …

698 Objectives: Accurate voxel-wise estimates of the (fractional) blood volume are essential
for quantification of pulmonary PET studies due to the large amount of blood in the lungs …
