Our understanding of regional filling of the lung and regional ventilation distribution is based
on studies using stepwise inhalation of radiolabelled tracer gases, magnetic resonance …

We develop dynamic breathing lung models for healthy and asthmatic subjects by utilizing
two or multiple volumetric multi-detector-row computed tomographic (MDCT) of lung images …

The continuous changes in lung mechanics were related to those in pulmonary vascular
resistance (Rv) during lung inflations to clarify the mechanical changes in the …

The gravitational gradient of intrapleural pressure is suggested to be less in prone posture
than supine. Thus the gravitational distribution of ventilation is expected to be more uniform …

We previously reported that apparent lung mass varies across the phases of 4D computed
tomography (4DCT) images. We hypothesize that these variations correspond to the …

The aim of our study was to check the effect of varying blood volume in the chest and gravity
on the distribution of ventilation and aeration in the lungs. The change in intrathoracic blood …

The distribution of pulmonary blood flow is influenced by gravity, regional lung expansion,
and hypoxic pulmonary vasoconstriction. However, these factors cannot completely explain …

To examine the effect of vasoconstriction on the gravity-nondependent distribution of
pulmonary blood flow, albumin macroaggregates labeled with either 99mTc or 111In were …

Validation of quantification of pulmonary blood flow (PBF) with dynamic, contrast‐enhanced
MRI is still missing. A possible reason certainly lies in difficulties based on the nonlinear …

Purpose To evaluate lung water density at three different levels of lung inflation in normal
lungs using a fast gradient echo sequence developed for rapid imaging. Materials and …
