[Value of modern study methods in the early diagnosis and assessment of asbestosis].

Results of examinations among 31 asbestos-workers with pleural hyalinosis are presented. The hyalinosis was ascertained by means of pleuroscopy and computed tomography. The value of both methods and special function tests in asbestosis is discussed. Diagnostic and expertising of early signs in asbestosis should not rely on x-ray of thorax but include selected and suitable function tests.
