This article reviews the potential use of positron emission tomography (PET), alone and in
combination with computed tomography, for evaluating the severity of disease in cystic …

PET with 18F-FDG may be useful for quantifying neutrophilic activation. We previously
demonstrated that pulmonary neutrophil sequestration could be detected during acute lung …

13N when coupled with a positron camera allows excellent quantification and imaging of
regional lung function. The studies can be readily repeated since the half-life of the 13N is …

18F-FDG positron emission tomographic (PET) scanning is a major imaging tool widely
used to investigate lung function and lung disease. Tomographic imaging of drug delivered …

Pulmonary PET imaging is still immature relative to developments and experience in other
fields, such as brain, heart, and cancer. The reasons for this are several, including …

Objective: Neutrophilic inflammation plays a key role in the pathogenesis of acute
respiratory distress syndrome (ARDS) and acute lung injury (ALI). Positron emission …

Several methods allow regional gas exchange to be inferred from imaging of regional
ventilation and perfusion (V/Q) ratios. Each method measures slightly different aspects of …

perfusion and ventilation to heterogeneity in V˙ a/Q˙ measured by PET. J. Appl. Physiol. 82 …

The current status of tests of regional lung function has been reviewed from the
physiological and clinical standpoint. Recent technical innovations include the use of single …

This paper presents a novel approach to visualizing regional lung function, through
quantitative three-dimensional maps of O 2 and CO 2 transfer rates. These maps describe …
