Microsphere technique is the reference for assessment of pulmonary blood flow (PBF) but is
destructive; PET, however, can determine PBF noninvasively. Comparisons of these 2 …

Respiratory and cardiac motion are a known source of image degradation and quantification
impairment in positron emission tomography (PET). In this study we use near-realistic …

Respiratory motion in PET and PET/CT blurs the images and can cause attenuation‐related
errors in quantitative parameters such as standard uptake values. In rare instances, this …

Respiratory motion during PET acquisition may lead to blurring in resulting images and
underestimation of uptake parameters. The advent of integrated PET/MR scanners allows us …

[en] The early application of positron emission tomography in the lung was mainly
concerned with the investigation of the regional volume of the vascular and extravascular …

667 Objectives: We present an analysis of respiratory tracking signals for respiratory gated
whole-body PET/CT imaging. Clinical PET/CT systems use gating triggers derived from …

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 …

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 …

Tracer kinetic modeling in dynamic PET has the potential to improve the diagnosis,
prognosis, and research of lung diseases. The advent of total-body PET systems with much …

Abstract Gated (4D) PET/CT has the potential to greatly improve the accuracy of
radiotherapy at treatment sites where internal organ motion is significant. However, the best …
