A. Gevenois, M. L. Van Sinoy, S. Dedeire, B. Stallenberg, J. Struyven emphasized the role of HRCT in characterization of benign asbestos-related diseases [9, 10] and concluded that HRCT can complement the evaluation of asbestos-exposed subjects when other criteria for parenchymal fibrosis are equivocal or absent [9]. To the best of our knowledge, no studies report the comparative accuracy of both conventional and high-resolution CT in detecting and characterizating of silicosis. Akira et al. [7] described high-resolution aspects of radiographic type p pneumoconiosis and concluded that addition of HRCT to chest radiography is useful in achieving more accurate categorization of the lesions.

Measurement times are limited by the output of the x-ray tube and the capacity of the image memory. At present, data acquisition of up to 12 s is possible. This means that 120 mm are acquired with a table feed of 10 mm/s. After the measurement, scans are reconstructed from the original data file with a newly developed algorithm ("spiral"). The scans are free from motion artifacts in spite of the table feed [Kalender et al. 1989]. 3; this means that a slice thickness of 10 mm represents an effective slice thickness of 13mm.
