Uneven distribution of ventilation, or ventilation heterogeneity, has been observed in asthma
for over 60 years using multiple breath nitrogen washout (MBNW) studies. Ventilation …

Regional lung density (LD) and lung water (LW) measurements were made with positron
transmission and emission tomography (PET) in normal and edematous lung in supine dogs …

Ventilation/perfusion single-photon emission computed tomography (V/P SPECT) is the
scintigraphic technique recommended primarily for the diagnosis of acute pulmonary …

Dear Sir, The trend in imaging—no matter if in radiology or nuclear medicine—goes towards
smaller voxels acquired in less time with less radiation dose. Thus, it is merely a matter of …

Positron emission tomography is a major technological advance in the characterisation of
structure-function relationships within and between regions in normal and abnormal lungs …

Pulmonary uptake of 18F-FDG assessed with PET has been used to quantify the metabolic
activity of inflammatory cells in the lung. This assessment involves modeling of tracer …

From the first measurements of the distribution of pulmonary blood flow using radioactive
tracers by West and colleagues (J Clin Invest 40: 1–12, 1961) allowing gravitational …

Positron emission tomography (PET) is emerging as a powerful tool that complements
conventional radiologic assessment (chest radiographs, CT scans, MR imaging) of thoracic …

Ventilation perfusion imaging using single photon emission tomography was carried out in
the supine position on four subjects, three normal volunteers and one patient, all free from …

Purpose The aim of this work was to non-invasively establish the feasibility of assessing 2-
deoxy-2-[18 F] fluoro-D-glucose (18 F-FDG) lung metabolism with the use of a late dynamic …
