Background Matched attenuation maps are vital for obtaining accurate and reproducible
kinetic and static parameter estimates from PET data. With increased interest in PET/CT …

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 …

1770 Objectives PET quantitation in the lung is affected by local density changes due to
respiration and hence needs accurate attenuation maps (AM) for attenuation correction (AC) …

PET quantitation depends on the accuracy of the CT-derived attenuation correction map. In
the lung, respiration leads to both positional and density mismatches, causing PET …

537 Objectives Lung density changes during respiration which affects PET/CT quantification
in the lung. We investigate the relation between density changes measured in CT, FDG …

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 …

In addition to static tracer uptake values used routinely in clinical facilities, PET imaging can
provide useful information on tracer kinetics via the use of dynamic acquisitions where a set …

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

Purpose PET/CT acquisitions are affected by physiological motion, which lowers the
quantization accuracy. Respiratory-gated PET/CT methods require a long acquisition time …

Purpose: Respiratory‐correlated positron emission tomography (PET/CT) 4D PET/CT is
used to mitigate errors from respiratory motion; however, the optimal CT attenuation …
