BACKGROUND Few studies have reported the diagnostic variability in patients with a possible usual interstitial pneumonia (UIP) pattern on high-resolution CT (HRCT) who underwent surgical lung biopsy (SLB), and the prognostic factors for these patients have not been fully evaluated. We retrospectively investigated the frequency of idiopathic pulmonary fibrosis (IPF) and prognostic factors in pat...
BACKGROUND The extent of lung involvement visualized by high-resolution computed tomography (HRCT) is a predictor of decline in forced vital capacity (FVC) in scleroderma-interstitial lung disease. Our objective was to evaluate the performance of three different HRCT-defined staging systems in the Scleroderma Lung Study I (SLS I) over a 1-year period. METHODS We assessed two visual semiquanti...
Making a confident diagnosis is a complex task for a specific form of interstitial lung disease and providing appropriate management in an attempt to achieve normalization of the disease can put up an alarming process for the clinicians. A set of diffuse and restrictive lung diseases incorporate with idiopathic interstitial pneumonias, showing inflammation and fibrosis of the interstitium due t...
OBJECTIVE To determine the High Resolution Computed Tomographic (HRCT) patterns in adults with Acid Fast Bacillus (AFB) positive new cases of Pulmonary Tuberculosis (PTB). STUDY DESIGN A descriptive case series. PLACE AND DURATION OF STUDY The study was carried out at the Department of Pulmonology and Department of Radiology, Military Hospital, Rawalpindi, from June 2006 to August 2007. M...
Idiopathic pulmonary fibrosis (IPF), the most prevalent idiopathic interstitial pneumonia, is associated with a poor prognosis. An accurate diagnosis of IPF is essential for optimal management. The recent ATS/ERS/JRS/ALAT recommendations on the diagnosis and management of IPF were developed from a systematic review of the published literature. High-resolution computed tomography (HRCT) scanning...
Background: Extrinsic allergic alveolitis belongs among the most often diagnosed interstitial lung diseases. However, little data concerning the impact of antigen-type, presentation of disease and treatment, on the patient ś prognosis, is available. Methods: Thirty eight patients were enrolled in a retrospective study. Data collected between January 2007 and December 2010 were analyzed. Patient...
Chronic beryllium disease (CBD) is a granulomatous disorder that affects the lung after exposure to beryllium. The present study reports short- and long-term evolution of granulomatous and fibrotic components in eight patients with severe CBD receiving corticosteroid therapy. Eight patients with confirmed CBD were studied at baseline, after initial corticosteroid treatment (4-12 months), at rel...
OBJECTIVE Methotrexate has a well-recognized side-effect of acute hypersensitivity pneumonitis. There is concern about whether chronic pulmonary toxicity can occur with methotrexate treatment. Our objective was to compare chest high-resolution computed tomography (HRCT) findings and serial pulmonary function tests in rheumatoid arthritis (RA) patients on methotrexate with findings for a control...
BACKGROUND Various radiologic patterns of cryptogenic organizing pneumonia (COP) in X-rays have been reported for more than 20 years, and later, in computed tomography scans. The aim of the present study was to describe the spectrum of radiologic findings on high resolution computed tomography (HRCT) scans in patients with COP. MATERIAL/METHODS HRCT scans of 31 sequential patients (mean age: ...
The goals of this study were (1) to evaluate the quality of compressed lung CT images obtained using high resolution CT (HRCT: 2 mm slice thickness) for degree of compression and conventional CT (10 mm slice thickness) images by using physical and subjective evaluations, and (2) to analyze the distortion of density distribution on lung CT images using histogram analysis for each compression rat...
