Association of findings in flow-volume spirometry with high-resolution computed tomography signs in asbestos-exposed male workers.
Disorders of pulmonary tissue and pleura are visualized by findings in high-resolution computed tomography (HRCT), and the impairment caused by these findings is assessed by pulmonary function tests. Our aim was to determine how some commonly used spirometric variables are related to certain HRCT signs, in order to find out which HRCT signs are associated with restrictive and which with obstructive ventilatory impairment. ⋯ HRCT signs showed distinctive patterns in restrictive and obstructive ventilatory impairment. These results can be used to help to analyse the lung function of patients simultaneously exposed to asbestos and smoking, when this relationship requires elucidation. In addition, the results may be helpful in explaining some radiological findings.
