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 …

Recently, there has been an increased interest in imaging different pulmonary disorders
using PET techniques. Previous work has shown, for static PET/CT, that air content in the …

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 …

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 …

Millions of people are affected by respiratory diseases, leading to a significant health burden
globally. Because of the current insufficient knowledge of the underlying mechanisms that …

Purpose The aim of this study is to assess a software-based method with semiautomated
correction for partial volume effect (PVE) to quantify the metabolic activity of pulmonary …

Regional lung density (LD) and lung water (LW) measurements were made with positron
transmission and emission tomography (PET) in normal and edematous lung in supine dogs …

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 …

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 …

Objectives Correction of the “partial volume effect” has been an area of great interest in the
recent times in quantitative PET imaging and has been mainly studied with count recovery …
