The mammalian lung´ s structural design is optimized to serve its main function: gas
exchange. It takes place in the alveolar region (parenchyma) where air and blood are …

Current computed tomography (CT) technology allows for near isotropic, submillimeter
resolution acquisition of the complete chest in a single breath hold. These thin-slice chest …

Under basal resting conditions most healthy physiologic systems demonstrate highly
irregular, complex dynamics that represent interacting regulatory processes operating over …

Chronic obstructive pulmonary disease (COPD) is characterized by the presence of airflow
obstruction caused by emphysema or airway narrowing, or both. Low attenuation areas …

Background: Cannabis is the most widely used illegal drug worldwide. Long-term use of
cannabis is known to cause chronic bronchitis and airflow obstruction, but the prevalence of …

Background Emphysematous change as assessed by CT imaging has been reported to
correlate with COPD prognostic factors such as FEV 1 and diffusing capacity of the lung for …

The biomechanical properties of connective tissues play fundamental roles in how
mechanical interactions of the body with its environment produce physical forces at the …

Purpose: To prospectively compare pulmonary function tests and helical computed
tomographic (CT) indexes for quantifying pulmonary emphysema with macroscopic and …

The lung parenchyma comprises a large number of thin-walled alveoli, forming an
enormous surface area, which serves to maintain proper gas exchange. The alveoli are held …

Quantitative computed tomography is being increasingly used to quantify the features of
chronic obstructive pulmonary disease, specifically emphysema, air trapping, and airway …
