Patient motion impacts single photon emission computed tomography (SPECT), positron
emission tomography (PET) and x-ray computed tomography (CT) by giving rise to …

Positron emission tomography (PET) is an important imaging modality for personalizing
clinical management of patients with lung cancer. In this regard, PET imaging is essential for …

Positron emission tomography (PET) is increasingly used for the detection, characterization,
and follow-up of tumors located in the thorax. However, patient respiratory motion presents a …

Background PET-based texture features have been used to quantify tumor heterogeneity
due to their predictive power in treatment outcome. We investigated the sensitivity of texture …

Purpose To assess the performance of hardware-and software-gating technologies in terms
of qualitative and quantitative characteristics of respiratory motion in positron emission …

2-deoxy-2-(18Fluorine)-fluoro-D-glucose (FDG) PET/CT is an integral part of lung carcinoma
staging and frequently used in the assessment of solitary pulmonary nodules. However, a …

Objective: Respiratory motion can degrade PET image quality and lead to inaccurate
quantification of lesion uptake. Such motion can be mitigated via respiratory gating. Our …

Many groups attempt to optimize imaging protocols on PET/MR imaging systems. Although
research protocols may take as long as 60–90 min, much more efficient clinical workflows …

Objectives: To evaluate the impact of fully automatic motion correction by data-driven
respiratory gating (DDG) on positron emission tomography (PET) image quality, lesion …

Purpose The aim of the present study was to evaluate the added diagnostic value of
respiratory-gated 4D18F–FDG PET/CT in liver lesion detection and characterization in a …
