Molecular imaging refers to the use of non-invasive imaging techniques to detect signals
that originate from molecules, often in the form of an injected tracer, and observe their …

Lung imaging has traditionally relied on x‐ray methods, since proton MRI is limited to some
extent by low proton density in the lung parenchyma and static field inhomogeneities in the …

Background One-lung ventilation (OLV) increases mechanical stress in the lung and affects
ventilation and perfusion (V, Q). There are no data on the effects of OLV on postoperative …

Emission tomography provides three-dimensional, quantitative images of the distribution of
radiotracers used to mark physiological, metabolic, or pathological processes. Quantitative …

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 …

Background The literature on ventilation (V) and lung perfusion (Q) distributions during
general anesthesia and controlled mechanical ventilation in supine and prone position is …

Although widely used for many years in the assessment of pulmonary embolism, planar
ventilation-perfusion (V/Q) scintigraphy has well-recognized limitations. Single-photon …

We used quantitative single photon emission computed tomography to estimate the
proportion of the observed redistribution of blood flow and ventilation that is due to lung …

We have developed a new quantitative single-photon-emission computed tomography
(SPECT) method that uses 113mIn-labeled albumin macroaggregates and Technegas …

Abstract Ventilation-perfusion (VA/Q) matching, the regional matching of the flow of fresh gas
to flow of deoxygenated capillary blood, is the most important mechanism affecting the …
