To determine the spatial distributions of pulmonary perfusion, shunt, and ventilation, we
developed a compartmental model of regional 13N-labeled molecular nitrogen (13NN) …

kinetics corrections on PET imaging of pulmonary function. J. Appl. Physiol. 82 (4): 1154 …

Positron emission tomography (PET) imaging is a noninvasive, quantitative method to
assess pulmonary perfusion and ventilation in vivo. The core of this article focuses on the …

We have measured regional pulmonary blood flow (PBF) in normal dogs with positron
emission tomography (PET) and 15O-labeled water (H2 (15) O). The method is …

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

Regional pulmonary perfusion and ventilation can be assessed by imaging, with positron
emission tomography (PET), the pulmonary kinetics of [13N] nitrogen (13N2). Because of its …

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 …

The adaptation to positron emission tomography of the steady-state technique for the
measurement of alveolar ventilation, based on the shortlived radionuclide neon-19 (T,= 17.4 …

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 …

In many ways, the lung is an ideal organ for study with positron emission tomography (PET).
First, structure-function relations are homogeneous over larger areas than in other organs …
