Comparison of Predicted Postoperative Lung Function in Pneumonectomy Using Computed Tomography and Lung Perfusion Scans

Journal of Chest Surgery, 2021
Background: Predicting postoperative lung function after pneumonectomy is essential. We retrospectively compared postoperative lung function to predicted postoperative lung function based on computed tomography (CT) volumetry and perfusion scintigraphy

Desaturation-Distance Ratio During Submaximal and Maximal Exercise Tests and Its Association With Lung Function Parameters in Patients With Lymphangioleiomyomatosis

Frontiers in Medicine, 2021
Background: The desaturation–distance ratio (DDR), the ratio of the desaturation area to the distance walked, is a promising, reliable, and simple physiologic tool for functional evaluation in subjects with interstitial lung diseases ...

Changes in Cross-Sectional Area and Transverse Diameter of the Heart on Inspiratory and Expiratory Chest CT: Correlation with Changes in Lung Size and Influence on Cardiothoracic Ratio Measurement. [PDF]

PLoS ONE, 2015
The aim of this study was to investigate physiological changes in cardiac area and diameters between inspiratory and expiratory chest computed tomography (CT), and to assess their correlation with lung size change and influence on cardiothoracic ratio ...

Lung volume measurements [PDF]

European Respiratory Journal, 2008
To the Editor: I read with interest the impressive paper by Cazzola et al. 1 in a recent issue of the European Respiratory Journal . However, I felt somewhat uneasy reading the recommendations on lung volume measurements, i.e. closing circuit dilution …

Air Trapping and the Risk of COPD Exacerbation: Analysis From Prospective KOCOSS Cohort

Frontiers in Medicine, 2022
Background and AimsAir trapping is a predictive index for a decline in lung function and mortality in patients with chronic obstructive pulmonary disease (COPD). However, the role of air trapping in COPD exacerbation has rarely been studied.

Automatic algorithm for quantifying lung involvement in patients with chronic obstructive pulmonary disease, infection with SARS-CoV-2, paracoccidioidomycosis and no lung disease patients

PLoS ONE, 2021
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

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
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 ...

Exclusion of emphysematous lung from dose-volume estimates of risk improves prediction of radiation pneumonitis

Radiation Oncology, 2017
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 ...

Supine posture changes lung volumes and increases ventilation heterogeneity in cystic fibrosis. [PDF]

PLoS ONE, 2017
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 ...
