Specific ventilation imaging (SVI) uses proton MRI to quantitatively map the distribution of
specific ventilation (SV) in the human lung, using inhaled oxygen as a contrast agent. To …

A substantial amount of life-sciences research has been performed in space since the
beginning of human spaceflight. Investigations into bone loss, for example, are well known; …

Asthma remains an important disease worldwide, causing high burden to patients and
healthcare systems and presenting a need for better management and ultimately prevention …

Pulmonary electrical impedance tomography (EIT) is a functional imaging technique that
allows real-time monitoring of ventilation distribution. Ventilation heterogeneity (VH) is a …

Abstract Ventilation-perfusion (VA/Q) matching, the regional matching of the flow of fresh gas
to flow of deoxygenated capillary blood, is the most important mechanism affecting the …

In asthma, bronchoconstriction causes topographically heterogeneous airway narrowing, as
measured by three-dimensional ventilation imaging. Computation modeling suggests that …

Purpose Three‐dimensional UTE MRI has shown the ability to provide simultaneous
structural and functional lung imaging, but it is limited by respiratory motion and relatively …

Chronic lung allograft dysfunction (CLAD) remains the leading cause of morbidity and
mortality after lung transplantation. Diagnosis requires spirometric change, which becomes …

Purpose To reduce the influence of tidal volume on fractional ventilation (FV) derived by
Fourier decomposition (FD). Methods Twelve volunteers were examined on a 1.5 Tesla …

Inhalation of e-cigarette's aerosols (vaping) has the potential to disrupt pulmonary gas
exchange, but the effects in asymptomatic users are unknown. We assessed ventilation …
