Lung densitometry assesses with computed tomography (CT) the X-ray attenuation of the
pulmonary tissue which reflects both the degree of inflation and the structural lung …

Background The aim of the study was to assess the relationship between computed
tomography (CT) densitometry and routine clinical markers in patients with chronic …

Multiple thoracic imaging modalities have been developed to link structure to function in the
diagnosis and monitoring of lung disease. Volumetric computed tomography (CT) renders …

Objectives Surgical or bronchoscopic lung volume reduction (BLVR) techniques can be
beneficial for heterogeneous emphysema. Post-processing software tools for lobar …

Novel therapeutic options in chronic obstructive pulmonary disease (COPD) require delicate
patient selection and thus demand for expert radiologists visually and quantitatively …

Alpha-1 antitrypsin deficiency (AATD) is characterized by low serum levels of or
dysfunctional alpha-1 proteinase inhibitor. In the lung parenchyma, this results in a loss of …

Objectives Densitometry on paired inspiratory and expiratory multidetector computed
tomography (MDCT) for the quantification of air trapping is an important approach to assess …

Objective To longitudinally evaluate effects of smoking cessation on quantitative CT in a
lung cancer screening cohort of heavy smokers over 4 years. Methods After 4 years, low …

Quantitative features obtained from computed tomography (CT) scans are being explored for
clinical applications. Various classes of quantitative features exist for chest CT including …

ABSTRACT Alpha-1 antitrypsin deficiency (AATD) is associated with premature onset of
emphysema resulting from low serum A1-PI levels. The only available pharmacological …
