PET/CT quantification of lung tissue is limited by several difficulties: the lung density and
local volume changes during respiration, the anatomical mismatch between PET and CT …

Aim To evaluate the effect of the 18F-FDG PET-CT respiratory gating (4D) study in the
correct documentation of pulmonary lesions with faint uptake in standard PET-CT. Methods …

Purpose It has recently been recognized that PET/CT may play a role in diffuse parenchymal
lung disease. However, interpretation can be confounded due to the variability in lung …

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 …

The use of PET in the staging of patients with NSCLC is cost-effective, mainly due to a
reduction in the number of futile operations. The addition of SUVmax to pathologic tumor …

Purpose: 4D positron emission tomography and computed tomography (PET/CT) can be
used to reduce motion artifacts by correlating the raw PET data with the respiratory cycle …

Respiratory motion during PET has a significant effect on the quantification of radiotracer
uptake in PET images. Even when respiratory motion is considered using PET gating …

Purpose Respiratory motion causes uptake in positron emission tomography (PET) images
of chest structures to spread out and misregister with the CT images. This misregistration …

Abstract Background Increased pulmonary 18 F-FDG metabolism in patients with idiopathic
pulmonary fibrosis, and other forms of diffuse parenchymal lung disease, can predict …

Accurate PET quantitation requires a matched attenuation map. Obtaining matched CT
attenuation maps in the thorax is difficult due to the respiratory cycle which causes both …
