Local driving pressures and resistances within the pulmonary vascular tree determine the
distribution of perfusion in the lung. Unlike other organs, these local determinants are …

Purpose: To investigate the influence of the contrast-to-noise ratio (CNR) and temporal
resolution of 3D dynamic contrast-enhanced magnetic resonance imaging on the …

Purpose Magnetic resonance imaging (MRI) allows for quantitative evaluation of pulmonary
perfusion and has shown high clinical usefulness for the evaluation and differentiation of …

Purpose To quantitatively evaluate lung perfusion using Fourier decomposition perfusion
MRI. The Fourier decomposition (FD) method is a noninvasive method for assessing …

Rationale and Objectives: The effect of breathholding on pulmonary perfusion remains
largely unknown. The aim of this study was to assess the effect of inspiratory and expiratory …

Measurement of ventilation heterogeneity with the multiple-breath nitrogen washout (MBW)
is usually performed using controlled breathing with a fixed tidal volume and breathing …

OBJECTIVE: To evaluate the effect of gravity and lung inflation on pulmonary perfusion
heterogeneity in human lung using an arterial spin labeling (ASL) sequence called flow …

Pulmonary perfusion is a fundamental parameter of lung function, since matched distribution
of the regional pulmonary blood flow (perfusion) and ventilation is a prerequisite for gas …

Purpose: The assessment of pulmonary perfusion using dynamic contrast-enhanced (DCE)
MRI is still limited in the clinical routine due to the necessity of breath holding. An acquisition …

In the human upright lung the downward increase in lung perfusion reverses in the lower
third, thus giving rise to a zone of reduced basal perfusion (zone 4). The flow in zone 4 is …
