Increased vascular permeability and consequent plasma leakage from postcapillary venules
is a cardinal sign of inflammation. Although the movement of plasma constituents from the …

Several methods allow regional gas exchange to be inferred from imaging of regional
ventilation and perfusion (V/Q) ratios. Each method measures slightly different aspects of …

With the incidence of respiratory diseases increasing throughout the world, new therapies
are needed. This review provides a short overview of different imaging techniques of interest …

Purpose The current algorithms for measuring ventilation images from 4D cone-beam
computed tomography (CBCT) are affected by the accuracy of deformable image registration …

Ex vivo rodent lung models are explored for physiological measurements of respiratory
function with hyperpolarized (hp) 129Xe MRI. It is shown that excised lung models allow for …

Purpose Currently, several active clinical trials of functional lung avoidance radiation
therapy using different imaging modalities for ventilation or perfusion are underway. Patients …

This article reviews the potential use of positron emission tomography (PET), alone and in
combination with computed tomography, for evaluating the severity of disease in cystic …

Human lungs weighing ca 600g permit the passage of 5–6l of blood per minute. The blood
capacity of the human lungs is about 0.5 l. Consequently, each 0.5 l of blood is during 5s …

OBJECTIVES: To evaluate the feasibility and incremental diagnostic value of xenon-
enhanced dual-energy CT in mechanically ventilated intensive care patients with worsening …

Omalizumab promotes clinical improvement in patients with allergic asthma, but its effect on
pulmonary function is unclear. One possibility is that omalizumab improves asthma …
