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: During the last few decades, high-resolution computed tomography
(HRCT) has come up as a new diagnostic modality to diagnose emphysematous and …

Computed tomography (CT) is an obvious modality for subclassification of COPD.
Traditionally, the pulmonary involvement of chronic obstructive pulmonary disease (COPD) …

Rationale: There is limited knowledge about the relationship between respiratory symptoms
and quantitative high-resolution computed tomography measures of emphysema and airway …

Computed tomography (CT) is the modality of choice for imaging the thorax and lung
structure. In chronic obstructive pulmonary disease (COPD), it used to recognise the key …

Computed tomography (CT) is used to detect emphysematous changes in the lungs of living
patients. It is therefore important to develop a standard method for the radiographic …

Computed tomography (CT) scanning allows precise assessment of both the extent and
distribution of emphysema. There has been little work on the relationship between the …

Background The contribution and role of emphysema and small airways disease in causing
expiratory airflow limitation in COPD is controversial. Methods We obtained high-resolution …

Rationale: Pulmonary hypertension (PH) is an established complication of advanced chronic
obstructive pulmonary disease (COPD) associated with increased mortality. The …

OBJECTIVE. The aim of this study was to identify ancillary morphologic features on high-
resolution CT that modify airflow obstruction and gas transfer levels in individuals with …
