Measurement of the Pressure-volume Curve in Mouse Lungs [PDF]

Journal of Visualized Experiments, 2015
In recent decades the mouse has become the primary animal model of a variety of lung diseases. In models of emphysema or fibrosis, the essential phenotypic changes are best assessed by measurement of the changes in lung elasticity. To best understand specific mechanisms underlying such pathologies in mice, it is essential to make functional ...

Repeatability of Metabolically Active Volume Measurements with¹⁸F-FDG and¹⁸F-FLT PET in Non–Small Cell Lung Cancer [PDF]

Journal of Nuclear Medicine, 2010
In addition to tumor size measurements with CT, there is a need for quantitative measurements of metabolic active volumes, possibly adding to tracer uptake measurements in oncologic response evaluation with PET.

ACCURACY OF MEASURED AND PREDICTED RESIDUAL LUNG VOLUME ON BODY DENSITY MEASUREMENT ERRORS

Medicine & Science in Sports & Exercise, 1984
The effects of measured and predicted residual lung volume on the accuracy of body density and percent fat (%Fat) were investigated. Adult fitness subjects (N = 46) had residual lung volume measured with the oxygen dilution method while those from an athlete sample (N = 134) utilized the nitrogen washout technique.

Intra- and Inter-Reader Variations in Lung Nodule Measurements: Influences of Nodule Size, Location, and Observers

Diagnostics, 2022
(1) Background: Accurate measurement of lung-nodule size is necessary, but whether a three-dimensional volume measurement is better or more reliable than the one-dimensional method is still unclear.

Measurement of lung volumes by plethysmography [PDF]

European Respiratory Journal, 1997
There are various ways of measuring absolute lung volume. These range from measurements derived from chest radiographs to the more common laboratory measurements employing either gas dilution or plethysmography. The principal difference between the latter two methods is that gas dilution techniques measure gas that is in free communication with the ...

A Correlation Between Quantitative Measurement Parameters of Thorax Computed Tomography and Pulmonary Function Test: A Retrospective Study

Namık Kemal Tıp Dergisi, 2021
Aim:Pulmonary functional and volumetric evaluation is routinely performed with pulmonary function test (PFT). However, volumetric evaluation is also possible in computed tomography (CT) imaging.
