Recent advances in imaging offer exciting opportunities to develop and validate lung-
specific biomarkers as valuable adjuncts to diagnosis, tests of treatment efficacy, and/or …

Lung imaging using conventional 1H MRI presents great challenges because of the low
density of lung tissue, lung motion and very fast lung tissue transverse relaxation (typical T2 …

Background Pulmonary vascular remodeling is essential for understanding the
pathogenesis of chronic obstructive pulmonary disease (COPD). The total cross-sectional …

Background Computed tomographic (CT) airway lumen narrowing is associated with lower
lung function. Although volumetric CT measures of airways (wall volume [WV] and lumen …

This article provides a brief overview of the important issues influencing the effective use of
quantitative X-ray computed tomography (QCT) in the assessment of the lung parenchyma …

Background In CT scans of smokers with COPD, the subsegmental airway wall area percent
(WA%) is greater and more strongly correlated with FEV 1% predicted than WA% obtained …

Identification of both the luminal and the wall areas of the bronchial tree structure from
volumetric X-ray computed tomography (CT) data sets is of critical importance in …

Pulmonary magnetic resonance (MR) imaging has been put forward as a new research and
diagnostic tool mainly to overcome the limitations of computed tomography and nuclear …

PURPOSE: The purpose of this study was to directly and prospectively compare the
capability of dynamic O2-enhanced MRI and quantitatively assessed thin-section MDCT to …

Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity
and mortality worldwide. COPD is defined by irreversible airflow obstruction. It is a …
