Purpose: To evaluate the feasibility and reproducibility of a noninvasive, rapid and
quantitative pulmonary perfusion mapping method using a two‐compartment tissue model in …

Purpose To present a technique for non‐contrast‐enhanced in vivo imaging of the blood
volume fraction of the human lung. The technique is based on the intravoxel incoherent …

Background Quantitative measurements of regional lung ventilation and perfusion are useful
adjuncts to image interpretation. Aim This study investigated the accuracy and precision of …

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 …

Rationale: regional and global features of asthmatic lungs from those of healthy lungs during
breathing. The objective of this study is two-fold. First is to estimate regional ventilation and …

An external respiratory surrogate that not only highly correlates with but also quantitatively
predicts internal tidal volume should be useful in guiding four-dimensional computed …

Purpose: To evaluate methods for quantification of pulmonary ventilation with ultrashort
echo time (UTE) MRI. Methods: We performed a reproducibility study, acquiring two free …

Purpose To assess semiquantitatively the regional distribution of lung perfusion using
magnetic resonance (MR) perfusion imaging. Materials and Methods Subjects were 20 …

We assessed the heterogeneity of regional pulmonary blood flow (PBFr), using radioactive
microspheres in five unanesthetized dogs standing at rest (Rest), standing at a 45 degrees …

In the upright individual the apex of the lung receives relatively little blood. This has often
been explained by the low pulmonary arterial pressure which is said to be just sufficient to …
