Early changes of lung function and structure in an elastase model of emphysema--a hyperpolarized 3He MRI study.
Early changes of lung function and structure were studied in the presence of an elastase-induced model of emphysema in 35 Sprague-Dawley rats at mild (5 U/100 g) and moderate (10 U/100 g) severities. Lung ventilation was measured on a regional basis (at a planar resolution of 3.2 mm) by hyperpolarized 3He MRI at 5 and 10 wk after model induction. Subsequent to imaging, average alveolar diameter...
متن کاملQuantitative in vivo assessment of lung microstructure at the alveolar level with hyperpolarized 3He diffusion MRI.
The study of lung emphysema dates back to the beginning of the 17th century. Nevertheless, a number of important questions remain unanswered because a quantitative localized characterization of emphysema requires knowledge of lung structure at the alveolar level in the intact living lung. This information is not available from traditional imaging modalities and pulmonary function tests. Herein,...

متن کاملQuantification of lung microstructure with hyperpolarized 3He diffusion MRI.
The structure and integrity of pulmonary acinar airways and their changes in different diseases are of great importance and interest to a broad range of physiologists and clinicians. The introduction of hyperpolarized gases has opened a door to in vivo studies of lungs with MRI. In this study we demonstrate that MRI-based measurements of hyperpolarized (3)He diffusivity in human lungs yield qua...
متن کاملEmphysematous changes and normal variation in smokers and COPD patients using diffusion 3He MRI.
INTRODUCTION This study aims to quantify global and regional changes of diffusive motion of 3He gas within the lung, as determined by hyperpolarized 3He MR apparent diffusion coefficient (ADC) measurement, in non-smokers, smokers and chronic obstructive pulmonary disease (COPD) patients. METHODS Age-matched groups of six healthy non-smokers, five healthy smokers and five patients with COPD. T...
