We studied 2240 indeterminate solid nodules (volume 50–500mm3) to determine the correlation of diameter and semi-automated volume measurements for pulmonary nodule size estimation.

Supine posture changes lung volumes and increases ventilation heterogeneity in cystic fibrosis. [PDF]
Lung Clearance Index (LCI) is recognised as an early marker of cystic fibrosis (CF) lung disease. The effect of posture on LCI however is important when considering longitudinal measurements from infancy and when comparing LCI to imaging studies.35 ...

Reference values play an important role in establishing whether, in an individual, measured volumes fall within a range to be expected for a healthy person of the same sex, similar stature, age, and other characteristics.

An apparatus for the measurement of lung volume and compliance in mice [PDF]
Pressure-volume (P-V) curves and total lung capacity (TLC) were measured in excised lung of mice using a water manometer and a closed system in which the humidity and temperature were controlled. In pathogen-free mice there are no significant differences in elastic properties of these lungs in relation to their age.

In this work, we aimed to develop an automatic algorithm for the quantification of total volume and lung impairments in four different diseases. The quantification was completely automatic based upon high resolution computed tomography exams.

Sleep‐Disordered Breathing, Hypoxia, and Pulmonary Physiologic Influences in Atrial Fibrillation
Background We leverage a large clinical cohort to elucidate sleep‐disordered breathing and sleep‐related hypoxia in incident atrial fibrillation (AF) development given the yet unclear contributions of sleep‐related hypoxia and pulmonary physiology in ...

Statistical analysis of lung nodule volume measurements with CT in a large-scale phantom study.
PURPOSE To determine inter-related factors that contribute substantially to measurement error of pulmonary nodule measurements with CT by assessing a large-scale dataset of phantom scans and to quantitatively validate the repeatability and ...

Background The risk factors for radiation pneumonitis (RP) in patients with chronic obstructive pulmonary disease (COPD) are unclear. Mean lung dose (MLD) and percentage of irradiated lung volume are common predictors of RP, but the most accurate ...

Methods for Measuring Lung Volumes: Is There a Better One? [PDF]
<b><i>Background:</i></b> Accurate measurement of lung volumes is of paramount importance to establish the presence of ventilatory defects and give insights for diagnostic and/or therapeutic purposes. <b><i>Objectives:</i></b> It was the aim of this study to measure lung volumes in subjects with ...
