چکیده

In the framework of computer-assisted diagnosis, pulmonary airway investigation based on multi detector computed tomography (MDCT) requires to provide radiologists and clinicians with advanced tools for interactive exploration, quantitative assessment and follow-up. This paper develops a set of automated investigation facilities relying on 3D airway reconstruction, enhanced central axis-based description and accurate meshing. By overcoming the limitations encountered by the current post-processing techniques available in clinical routine, the proposed tools contribute to increase the diagnosis confidence level and provide better insights into the physiopathology of airways.

ارزش عملی لاواژ برونکوآلوئولار در کشف عفونت های ریوی

Aim: It is believed that sampling of the lower airways by BAL in complicated patients with pulmonary infection is often contaminated with upper airways microorganisms. The aim of this study was to assess the value of this procedure and probability of contamination of samples by upper airways flora. Methods: In a prospective study 40 consecutive patients which were candidate for broncholaveolar ...

Investigation of airways using MDCT for visual and quantitative assessment in COPD patients

Multidetector computed tomography (MDCT) acquisition during a single breath hold using thin collimation provides high resolution volumetric data set permitting multiplanar and three dimensional reconstruction of the proximal airways. In chronic obstructive pulmonary disease (COPD) patients, this technique provides an accurate assessment of bronchial wall thickening, tracheobronchial deformation...

Assessment of Alpha-1 Antitrypsin Deficiency in Patients with Severe Chronic Obstructive Pulmonary Disease

Background and Aims: Chronic obstructive pulmonary disease (COPD) is a kind of pulmonary diseases characterized by chronic obstruction of lung that is in the form of a diffuse narrowing of airways resulting in air flow resistance. Alpha-1 antitrypsin (AAT) deficiency is genetically relatively common risk factor in patients with COPD throughout the world and the exact cause of its prevalence is ...

Automated classification of pulmonary nodules through a retrospective analysis of conventional CT and two-phase PET images in patients undergoing biopsy

Objective(s): Positron emission tomography/computed tomography (PET/CT) examination is commonly used for the evaluation of pulmonary nodules since it provides both anatomical and functional information. However, given the dependence of this evaluation on physician’s subjective judgment, the results could be variable. The purpose of this study was to develop an automated scheme for the classific...

Correlation Between Upper Airways Obstructive Indexes in Adenotonsilar Hypertrophy with Mean Pulmonary Arterial Pressure

Introduction: Hypertrophied tonsils and adenoids may cause upper airway obstruction and cardio-pulmonary complications due to pulmonary arterial hypertension. The aim of this study was to determine the correlation between mean pulmonary arterial pressure (mPAP) and selected adenotonsilar hypertrophy indexes. Materials and Methods: Thirty two patients with upper-airway obstruction resulting ...
