Oxygen-enhanced MR imaging is a new technique, and its physiological significance has
not yet been fully elucidated. This review article covers (1) the theory of oxygen …

Purpose To evaluate the effect of inhaled 100% oxygen on pulmonary circulation dynamics
in healthy volunteers using 2D phase‐contrast magnetic resonance imaging (2D PC MRI) …

Normal aging is associated with a decline in pulmonary function and efficiency of gas
exchange, although the effects on the spatial distribution of pulmonary perfusion are poorly …

Specific ventilation imaging (SVI) is a functional magnetic resonance imaging technique
capable of quantifying specific ventilation―the ratio of the fresh gas entering a lung region …

Blood perfusion in lung parenchyma is an important property for assessing lung function. In
small animals, its quantitation is limited even with radioactive isotopes or dynamic contrast …

Rationale: Inhomogeneous hypoxic pulmonary vasoconstriction causing regional
overperfusion and high capillary pressure is postulated for explaining how high pulmonary …

Aim Specific ventilation (SV), the ratio of fresh gas entering a lung region to end-expiratory
volume, is a measure of regional ventilation. We have recently published (J Appl Physiol …

Purpose Contrast‐free lung MRI based on Fourier decomposition is an attractive method to
monitor various lung diseases. However, the accuracy of the current perfusion quantification …

Elevation of regional pulmonary resistance in response to local alveolar hypoxia is a near-
universal response of the mammalian lung to optimize arterial oxygenation (14). Given the …

PURPOSE: To evaluate partially parallel three-dimensional (3D) magnetic resonance (MR)
imaging for assessment of regional lung perfusion in healthy volunteers and patients …
