Background Idiopathic pulmonary fibrosis is responsible for 40,000 deaths annually in the
United States. A hallmark of idiopathic pulmonary fibrosis is elevated collagen deposition …

Purpose To develop a rapid proton MR elastography (MRE) technique that can quantify the
absolute shear stiffness of lung parenchyma, to investigate the ability to differentiate …

Purpose The purpose of this study is to evaluate the influence of different field strengths on
perfusion and ventilation parameters, SNR and CNR derived by PREFUL MRI using …

Objective To evaluate whether magnetic resonance imaging (MRI) is effective as computed
tomography (CT) in determining morphologic and functional pulmonary changes in patients …

Background Imaging of the lung by MRI is challenging due to the intrinsic low proton density
and rapid T2* relaxation. MRI methods providing lung parenchyma and function are in …

Purpose To introduce a method based on multivolume proton (hydrogen [1H]) magnetic
resonance (MR) imaging for the regional assessment of lung ventilatory function …

Since the lung receives the entire cardiac output, sophisticated imaging techniques are not
required in order to measure total organ perfusion. However, for many years studying lung …

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 …

Abstract Objective The Fourier decomposition (FD) method is a noninvasive method for
assessing ventilation and perfusion-related information in the lungs, but the lack of …

Purpose Measure the changes in relative lung water density (rLWD), lung volume, and total
lung water content as a function of time after supine body positioning. Methods An efficient …
