A method for automatically quantifying emphysema regions using High-Resolution Computed Tomography (HRCT) scans of patients with chronic obstructive pulmonary disease (COPD) that does not require manually annotated scans for training is presented. HRCT scans of controls and of COPD patients with diverse disease severity are acquired at two different centers. Textural features from co-occurrence...

Objective: The purpose of this study was to evaluate the effect of radiation dose reduction on the quantification of air trapping on expiratory CT. Materials and methods: This study was conducted as a retrospective evaluation of inspiratory and expiratory CT studies performed in routine clinical practice before and after alteration of the scanning protocol for expiratory CT at our institute. Ei...

BACKGROUND In several studies, low spirometric levels have been shown to increase the success rates of smoking cessation, whereas other studies have indicated that pulmonary function has no effects on quitting smoking. Given the fact that there are contradictory results on this subject, we aimed to investigate the effect of identifying airway obstruction via spirometry and its explanation to su...

OBJECTIVE To evaluate the influence of thoracic spine curvature on lung parameters in kyphoscoliosis. METHODS Twenty-one patients with kyphoscoliosis were evaluated at the Vallabhbhai Patel Chest Institute, Delhi, India from January to June 2006 using spirometry, arterial blood gas (ABG), and 6-minute walk test. The degree of spinal deformity was measured by Cobb`s method for angle of scolios...

Yogic practices can be used as psycho-physiological stimuli to increase in physiological functions and human performance. Yoga breathing or Pranayama is the science of breath control. Rapid succession of forcible expulsion is a characteristic feature of Bhastrika Pranayama. To determine the effects of Bhastrika Pranayama on Vital Capacity of lung (PFT), sixty (n = 60) randomly selected voluntee...

Rheumatoid arthritis (RA) is a chronic systemic disease of unknown etiology characterized by articular involvement, extra-articular involvement, and the presence of serum rheumatoid factor. Pulmonary involvement in RA is a common extra-articular manifestation of rheumatoid arthritis (RA) that confers significant morbidity and mortality. We undertook this study to determine the prevalence and sp...

BACKGROUND Primary hypogammaglobulinemia disorders are a group of heterogeneous immunodeficiency syndromes with an increased susceptibility to pulmonary complications. METHODS The aim of this study was to evaluate the extent of lung abnormalities in primary hypogammaglobulinaemic patients by high resolution computed tomography (HRCT) scan and pulmonary function test (PFT). HRCT and PFT were p...

Objective: The aim of this preliminary study was to evaluate the feasibility of exercise testing (ET) for predicting postoperative complications in patients with impaired pulmonary function. Methods: Thirteen patients were prospectively enrolled. The enrollment criteria were FEV1.0% < 70% and emphysema score > 8 by the Goddard classification or interstitial pneumonia on chest computed tomograph...
