Lung volume reduction for emphysema [PDF]

open access: yesThe Lancet Respiratory Medicine, 2017
Advanced emphysema is a lung disease in which alveolar capillary units are destroyed and supporting tissue is lost. The combined effect of reduced gas exchange and changes in airway dynamics impairs expiratory airflow and leads to progressive air trapping. Pharmacological therapies have limited effects. Surgical resection of the most destroyed sections

Differences in lung and lobe volumes between supine and upright computed tomography in patients with idiopathic lung fibrosis

open access: yesScientific Reports, 2022
No clinical study has compared lung or lobe volumes on computed tomography (CT) between the supine and standing positions in patients with idiopathic lung fibrosis (IPF).

Evaluation of respiratory function indicators of elite athletes in academic rowing using the method of computer spirography

open access: yesPedagogy of Physical Culture and Sports, 2023
Background and Study Aim. In modern sports, the research and study of the functional capabilities of athletes' breathing is relevant. The analysis of individual results made it possible to form an idea about the respiratory functions of athletes.

Diagnostic performance of lung volumes in assessment of reversibility in chronic obstructive pulmonary disease

open access: yesThe Egyptian Journal of Bronchology, 2021
Background Reversibility measured by spirometry in chronic obstructive pulmonary disease (COPD) is defined as an increase in forced expiratory volume in first second (FEV1) that is both more than 12% and 200 mL above the pre-bronchodilator value in ...

Lung Volume Reduction Reoperations [PDF]

open access: yesThe Annals of Thoracic Surgery, 2008
Optimal management of emphysematous patients who have lost the benefits achieved after lung volume reduction surgery is a clinical dilemma. We have hypothesized that in stringently selected instances, lung volume reduction reoperations might be considered as a salvage surgical treatment.

Kernel-based framework to estimate deformations of pneumothorax lung using relative position of anatomical landmarks [PDF]

open access: yesExpert Systems with Applications, 183(2021), 115288, 2021
In video-assisted thoracoscopic surgeries, successful procedures of nodule resection are highly dependent on the precise estimation of lung deformation between the inflated lung in the computed tomography (CT) images during preoperative planning and the deflated lung in the treatment views during surgery.

Combined Pulmonary Fibrosis and Emphysema: Pulmonary Function Testing and a Pathophysiology Perspective

open access: yesMedicina, 2019
Combined pulmonary fibrosis and emphysema (CPFE) has been increasingly recognized over the past 10−15 years as a clinical entity characterized by rather severe imaging and gas exchange abnormalities, but often only mild impairment in spirometric ...

Reference values for lung function tests: I. Static volumes [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 1999
Static lung volume (LV) measurements have a number of clinical and research applications; however, no previous studies have provided reference values for such tests using a healthy sample of the adult Brazilian population.

Automated Estimation of Total Lung Volume using Chest Radiographs and Deep Learning [PDF]

open access: yes, 2021
Total lung volume is an important quantitative biomarker and is used for the assessment of restrictive lung diseases. In this study, we investigate the performance of several deep-learning approaches for automated measurement of total lung volume from chest radiographs.

Quantification of lung function on CT images based on pulmonary radiomic filtering [PDF]

open access: yes, 2021
Purpose: To develop a radiomics filtering technique for characterizing spatial-encoded regional pulmonary ventilation information on lung CT. Methods: The lung volume was segmented on 46 CT images, and a 3D sliding window kernel was implemented across the lung volume to capture the spatial-encoded image information.
