This review provides an overview of the relationship between ventilation/perfusion ratios
and gas exchange in the lung, emphasising basic concepts and relating them to clinical …

The field of proton lung MRI is advancing on a variety of fronts. In the realm of functional
imaging, it is now possible to use arterial spin labeling (ASL) and oxygen‐enhanced …

Objectives To provide an overview of recent research in fractal analysis of tissue perfusion
imaging, using standard radiological and nuclear medicine imaging techniques including …

Hypoxic pulmonary vasoconstriction (HPV) is an adaptive response unique to the lung
whereby blood flow is diverted away from areas of low alveolar oxygen to improve …

Beyond being a substitute for X-ray, computed tomography, and scintigraphy, magnetic
resonance imaging (MRI) inherently combines morphologic and functional information more …

The Zone model of pulmonary perfusion predicts that exercise reduces perfusion
heterogeneity because increased vascular pressure redistributes flow to gravitationally …
