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

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

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

This is a review of some of the main findings obtained by positron emission tomography
(PET) concerning the pathophysiology of acute respiratory distress syndrome (ARDS) and …

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 …

The detailed investigation of regional differences in lung function at a local level began
when suitable gamma-ray emitting isotopes and focused external radiation detectors …

A new quantitative method, †œSimultaneousExponential Equation method―(SEE), has
been developed for the analysis of pulmonary ventilation studies using 13N-labeled …

Physiological conditions and pathophysiological changes in the lungs may affect many
applications in aerosol medicine and pulmonary drug delivery. In the diseased lung, spatial …

The authors measured the regional pulmonary ventilation/perfusion ratio with intravenous
13 N in saline solution, using positron emission tomography, in eight normal healthy …
