Nonuniform disruption of lung architecture is usually assessed by CT, which carries potential
radiation risk. Here we report our use of a three‐dimensional ultrashort echo time MR …

Magnetic resonance imaging (MRI) may provide attractive biomarkers for assessment of
pulmonary disease in clinical trials as it is free from ionizing radiation, minimally invasive …

Background To evaluate ultra‐short‐echo‐time (UTE) MRI pulmonary signal‐intensity
measurements and reproducibility in chronic obstructive pulmonary disease (COPD) …

PURPOSE: To quantitatively evaluate hyperpolarized helium 3 (3He) diffusion magnetic
resonance (MR) images of the lung in patients with emphysema and to determine whether …

Purpose To provide a robust method for the simultaneous quantification of T1 and T2* in the
human lung during free breathing. Breathing pure oxygen accelerates T1 and T2* relaxation …

Assessment of lung effective transverse relaxation time (T2*) may play an important role in
the detection of structural and functional changes caused by lung diseases such as …

Emphysema tends to be complicated by diffuse abnormalities in the pulmonary peripheral
microvasculature. The aim of this study was to evaluate whether dynamic contrast-enhanced …

Purpose To measure the apparent diffusion coefficient (ADC) of hyperpolarized (HP) 3He
gas using diffusion weighted MRI in healthy volunteers and patients with emphysema and …

Purpose To measure regional specific ventilation with free-breathing hydrogen 1 (1H)
magnetic resonance (MR) imaging without exogenous contrast material and to investigate …

To assess the stability and reproducibility of different breath-hold levels in healthy volunteers
and patients using dynamic MRI (dMRI). In ten healthy volunteers and ten patients with …
