Background To evaluate the effect of radiation dose and scanner manufacturer on
quantitative CT scan measurements of lung morphology in smokers. Methods Low-dose and …

In addition to providing useful visual information, computed tomography (CT) can also be
used for estimating tissue density. In the case of the lung, a structure exhibiting a wide …

RATIONALE AND OBJECTIVES: To evaluate the relationship between measurements of
lung volume (LV) on inspiratory/expiratory computed tomography (CT) scans, pulmonary …

Computed tomographic (CT) lung density measurements were prospectively correlated with
pulmonary haemodynamic data in 33 patients with chronic heart disease. Cardiac …

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 …

Purpose To compare mean lung density (MLD) of paired inspiratory and expiratory thin-
section CT scans acquired after patient instruction or using spirometric gating. Materials and …

PURPOSE: To investigate the inter-scan repeatability of CT-based lung densitometry
protocols in the surveillance of emphysema in a lung cancer screening setting. MATERIALS …

Objective Our goal was to establish the reproducibility and accuracy of the CT scanner in
densitometry of the lungs. Materials and Methods Scanner stability was assessed by …

SUMMARY CT densitometry of the lung is a sensitive and readily available noninvasive
method for determining regional and global lung density. Automated computer analysis …

Quantitative computed tomography (QCT) can provide reliable and valid measures of lung
structure and volumes. Similar to lung function measured by spirometry, lung measures …
