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

We have measured regional pulmonary blood flow (PBF) in normal dogs with positron

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 …

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 …
