Xenon-129 has become the isotope of choice for applications of hyperpolarized (HP) noble
gases in magnetic resonance imaging (MRI) and spectroscopy due to its lower cost and …

Lungs are considered one of the vital organs in the human body. They continuously
experience various mechanical stresses caused by the natural physiology of breathing …

Ventilation-perfusion (V/Q) scan plays an important role in the assessment of lung function.
Currently, Fourier Decomposition (FD), a method for simultaneous ventilation and perfusion …

Lung stiffness changes with different diseases; in which some diseases make the lung stiffer
while others make it softer. This study was performed on 15 healthy volunteers to validate …

Pulmonary imaging with conventional MRI remains challenging, owing to the low proton
density of lung tissue and magnetic susceptibility gradients that exist at ubiquitous air-tissue …

The respiratory function in human cannot be separated from the deformation motion of the
lung: the gas exchanges between the organism and its environment are made possible …

MRI of exogenous imaging agents offers a safely repeatable modality to assess regional
pulmonary ventilation. A small number of studies have validated the safety and potential …

Water contributes 80% of the lung components; however, most of them existed in the blood
vessels and distributed in a gradient of increasing density from nondependent to dependent …

Abstract Hyperpolarized (HP) 129 Xe MRI has emerged as a viable tool for evaluating lung
function without ionizing radiation. HP 129 Xe has already been used to image ventilation …

Interstitial lung diseases alter the mechanical properties of the lung parenchyma. Lung
stiffness is a potential diagnostic marker. Standard breath hold techniques are difficult for …
