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 …

Lung ventilation/perfusion (V/Q) positron emission tomography-computed tomography
(PET/CT) is a promising imaging modality for regional lung function assessment. The same …

Ventilation imaging using positron emission tomography (PET) and highly insoluble nitrogen
13 (N-13) was performed in one healthy volunteer and ten patients. These PET studies …

The impact of positron range on PET image reconstruction has often been investigated as a
blurring effect that can be partly corrected by adding an element to the PET system matrix in …

Pulmonary function tests (PFTs) are routinely used to assess lung function, but they do not
provide information about regional pulmonary dysfunction. We aimed to assess correlation …

Methods Fifty-three patients (24 male and 29 female) underwent lung scintigraphy with 68
Ga-labelled radiopharmaceuticals. 68 Ga Galligas and B20 microspheres used for V and Q …

The role of the fluorodeoxyglucose (FDG) technique positron emission tomography (PET) is
well established in the management of patients with lung cancer. Increasingly, it is becoming …

We have measured with positron emission tomography (PET) the regional distribution of
extravascular lung water (EVLW) and hematocrit (HctL) in normal supine dogs. H2 (15) O …

Microsphere technique is the reference for assessment of pulmonary blood flow (PBF) but is
destructive; PET, however, can determine PBF noninvasively. Comparisons of these 2 …

BACKGROUND: Positron emission tomography, performed with isotopes of very short half
life, can be used to relate local lung tissue density to local ventilation and to the ventilation …
