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 …

RATIONALE AND OBJECTIVES: To define a statistically based variation of individual whole-
lung densitometry above which a real increase of pulmonary extent can be suspected in …

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 …

Purpose: To retrospectively establish the minimum increase in emphysema score (ES)
required for detection of real increased extent of emphysema with 95% confidence by using …

Objectives: The objectives of this study were to investigate whether computed tomography
(CT) densitometry can be applied consistently in different centers; and to evaluate the …

Currently, lung densitometry for the assessment of pulmonary emphysema has been fully
validated against pathology, pulmonary function, and health status, and it is therefore being …

The aim of this study was to assess the reproducibility of quantitative, spirometrically gated
computed tomographic (CT) lung densitometry at defined levels of inspiration in hospitalized …

Purpose High-resolution computed tomography (CT) is a validated method to quantify the
extent of pulmonary emphysema. In this study, we assessed the reliability of low-dose …

We compared whole-lung densitometry with visual evaluation of pulmonary emphysema.
Thirty patients with chronic obstructive pulmonary disease underwent multi-detector CT (150 …

BACKGROUND: The role of computerised tomography (CT) lung density measurements in
objective quantification of emphysema is uncertain. The aim of this study was to determine …
