title: The diagnostic value of conventional X-ray examination of the lungs in comparison with high-resolution computed tomography (HRCT), isotope perfusion scintigraphy and the diffusion capacity in patients with pneumoconiosis.
abstract: A precise diagnosis of initial reticular forms of pneumoconioses is very difficult. The present study focuses on 30 patients with initial reticular forms of silicosis, asbestos induced interstitial lung fibrosis, mixed dust pneumoconioses and pneumoconioses of electrowelders. The anterior-posterior chest radiography (according to the ILO International Radiological Classification of Pneumoconioses, 1980), high-resolution computed tomography (HRCT), perfusion scintigraphy with 99mTc and the changes in the diffusion capacity were compared. The diagnostic value of these methods was assessed. The study continues by expanding the groups of patients examined and by including the membrane component of diffusion.
