Purpose. Respiratory motion presents significant challenges for accurate PET/CT. It often
introduces apparent increase of lesion size, reduction of measured standardized uptake …

This study proposes a new method to reduce respiratory motion artifacts in PET images of
lung cancer. The method is referred to as respiratory-correlated dynamic PET (RCDPET) …

Objectives Positron emission tomography acquisition takes several minutes representing an
image averaged over multiple breathing cycles. Therefore, in areas influenced by respiratory …

Purpose: Respiratory motion during PET/CT imaging can cause substantial image blurring
and underestimation of tracer concentration for both static and dynamic studies. In this study …

Purpose Respiratory motion of patients during positron emission tomography
(PET)/computed tomography (CT) imaging affects both image quality and quantitative …

Purpose: We present a method to correct respiratory motion blurring in PET/CT imaging
using internal–external (INTEX) motion correlation. The internal motion of a known tumor is …

Purpose Respiratory motion causes substantial artifacts in reconstructed PET images when
using helical CT as the attenuation map in PET/CT imaging. In this study, we aimed to …

Our aim is to investigate the impact of respiratory motion on tumor quantification and
delineation in static PET/CT imaging using a population of patient respiratory traces. A total …

Respiratory motion blurs the standardized uptake value (SUV) and leads to a further signal
reduction and changes in the SUV maxima. 4D PET can provide accurate tumor localization …

Combined PET/computed tomography (CT) is of value in cancer diagnosis, follow-up, and
treatment planning. For cancers located in the thorax or abdomen, the patient's breathing …
