Recently, PET systems with a long axial field of view have become the current state of the
art. Total-body PET scanners enable unique possibilities for scientific research and clinical …

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 …

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

Purpose To assess regional differences in quantitative pulmonary perfusion parameters, ie,
pulmonary blood flow (PBF), mean transit time (MTT), and pulmonary blood volume (PBV) in …

Recent evidence suggests that endothelial dysfunction and pathology of pulmonary vascular
responses may serve as a precursor to smoking-associated emphysema. Although it is …

Multiple thoracic imaging modalities have been developed to link structure to function in the
diagnosis and monitoring of lung disease. Volumetric computed tomography (CT) renders …

With ongoing technical improvements such as multichannel MRI, systems with powerful
gradients as well as the development of innovative pulse sequence techniques …

Purpose To quantitatively evaluate lung perfusion using Fourier decomposition perfusion
MRI. The Fourier decomposition (FD) method is a noninvasive method for assessing …

Rationale and Objectives: We sought to optimize the dosage of a paramagnetic contrast
medium (CM) for the quantification of pulmonary blood flow and volume by contrast …

Redistribution of pulmonary blood flow (PBF) away from edematous regions of the lung is
characteristic of experimental acute lung injury (ALI), helping to preserve ventilation …
