Positron emission tomography (PET) provides three-dimensional images of the distributions
of radionuclides that have been inhaled or injected into the lungs. By using radionuclides …

This thoroughly revised and expanded reference provides authoritative discussions on the
physiologic, pharmacologic, metabolic, molecular, cellular and physicochemical factors …

With the emergence of multidetector-row computed tomography (CT) it is now possible to
image both structure and function via use of a single imaging modality. Breath-hold spiral CT …

Using positron emission tomography (PET) and intravenously injected 13N2, we assessed
the topographical distribution of pulmonary perfusion (Q˙) and ventilation (V˙) in six healthy …

Two calculation methods to produce ventilation images from four-dimensional computed
tomography (4DCT) acquired without added contrast have been reported. We reported a …

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 …

In this pilot study, algorithms for quantitatively evaluating the distribution and heterogeneity
of human ventilation imaged with hyperpolarized (HP) 3He MRI were developed for the goal …

The topographic matching of alveolar ventilation (V̇ A) and perfusion (Q̇) is the main
determinant of gas exchange efficiency of the lung. However, no pulmonary functional …

Multiple thoracic imaging modalities have been developed to link structure to function in the
diagnosis and monitoring of lung disease. Volumetric computed tomography (CT) renders …

Rationale: Bronchoconstriction in asthma leads to heterogeneous ventilation and the
formation of large and contiguous ventilation defects in the lungs. However, the regional …
