BACKGROUND Considerable research has been conducted into the nature of airway inflammation in chronic obstructive pulmonary disease (COPD) but the relationship between proximal airways inflammation and both dynamic collapse of the peripheral airways and HRCT determined emphysema severity remains unknown. A number of research tools have been combined to study smokers with a range of COPD severit...

  Introduction: Data on imaging findings in pulmonary complications of chemical agents is scarce. The current study aimed to evaluate radiological findings of late onset pulmonary complications in chemical warfare victims (CWV) and to guide pulmonologists in diagnosis of these subjects.   Materials and Methods: Ninety- three male CWV were enrolled in this prospective study, 20-25 years (mean=23...

BACKGROUND The aim of this study was to assess the psychological consequences of HRCT scan screening in retired asbestos-exposed workers. METHODS A HRCT-scan screening program for asbestos-related diseases was carried out in four regions of France. At baseline (T1), subjects filled in self-administered occupational questionnaires. In two of the regions, subjects also received a validated psyc...

OBJECTIVE To evaluate the high resolution computed tomography (HRCT) findings of bronchiolitis obliterans (BO) after bone marrow transplantation (BMT). MATERIALS AND METHODS During the past three years, 11 patients were diagnosed as having BO after BMT when they developed irreversible air flow obstruction, with an FEV(1) value of less than 80% of the baseline value, without any clinical evide...

BACKGROUND High-resolution CT (HRCT) scan data on primary ciliary dyskinesia (PCD) related lung disease are scarce. STUDY OBJECTIVES We evaluated the lung disease in children and adults with PCD by a modified Brody composite HRCT scan score to assess the prevalence of the structural abnormalities; to evaluate the correlation among HRCT scan scores, spirometry findings, and clinical data; and ...

327 High-Resolution Computerized Tomography (HRCT) of the lung is now a well-established and widely used technique in the management of respiratory disease. It is the only imaging technique currently available that allows the in vivo visualization of the secondary pulmonary lobule. 1 This unique ability has enabled HRCT to revolutionize not only the diagnosis, but also the understanding of inte...

CONTEXT AND OBJECTIVE High-resolution computed tomography (HRCT) of the lungs is more sensitive than radiographs for evaluating pulmonary disease, but little has been described about HRCT interpretation during the neonatal period or shortly afterwards. The aim here was to evaluate the reliability of the interpretation of HRCT among very low birth weight premature infants (VLBWPI; < 1500 g). D...

RATIONALE High resolution computed tomography (HRCT) is a more sensitive tool for detecting early cystic fibrosis (CF) lung disease than either spirometry or plain radiography, but its relationship to other measures of lung function has not been established in young children. OBJECTIVES (1) To assess whether the lung clearance index (LCI) derived from multiple breath inert-gas washout (MBW) i...

AIM To determine the sensitivity and specificity of high resolution computed tomography (HRCT) in the diagnosis of otosclerosis. METHODS A systematic literature review was undertaken to include Level I-III studies (Oxford Centre for Evidenced based Medicine) that utilised HRCT to detect histology confirmed otosclerosis. Quantitative synthesis was then performed. RESULTS Based on available l...

dr.mirsadraei and colleagues performed an interesting study about the lung hrct findings in chemical warfare patients who suffering from long-term pulmonary complications. they found that air trapping and mosaic attenuation were the most common lung hrct findings. also they divided patients in different clinical entities according to the lung hrct findings (bronchiolitis oblitrans, pulmonary fi...
