OBJECTIVE. The aim of this study was to evaluate prospectively the effects of respiratory
gating during FDG PET/CT on the determination of lesion size and the measurement of …

Respiratory motion may reduce the sensitivity of 18F-FDG PET for the detection of small
pulmonary nodules close to the base of the lungs. This motion also interferes with attempts …

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 …

A computer-aided method was developed to automatically localize tumors in lung PET
images of discrete bins within the breathing cycle, followed by an algorithm that registers all …

We have reported in our previous studies on the methodology, and feasibility of 4D‐PET
(Gated PET) acquisition, to reduce respiratory motion artifact in PET imaging of the thorax. In …

1741 Objectives: Respiratory motion in PET degrades images and limits detectability and
characterization of small or low-contrast lesions. Although image quality can in principle be …

OBJECTIVE. PET/CT provides a fusion of both anatomic and functional information.
However, because of the temporal difference of both modalities and respiratory motion of …

Background Fluorine-18-fluorodeoxyglucose (18 F-FDG) PET/computed tomography (CT) is
a reliable imaging modality for the diagnosis of malignant lung nodules and to assess the …

Background Respiratory motion artefacts are a pitfall in thoracic PET/CT imaging. A source
of these motion artefacts within PET images is the CT used for attenuation correction of the …

Purpose Respiratory gating is an established approach to overcoming respiration-induced
image artefacts in PET. Of special interest in this respect are raw PET data-driven gating …
