[X-ray computed tomography in pleuropulmonary asbestos pathology].

Results of computed tomography and conventional radiology were compared during investigation of 17 patients with pleuropulmonary lesions from confirmed asbestosis. Computed tomography images appeared to provide improved data for detection and analysis of pleural plaques, particularly in the costovertebral grooves; false pleural images (associated shadows, fatty tissue) can be eliminated. The CT scan should occupy a place of choice for surveillance of subjects in contact with asbestos and presenting pleural anomalies.
