ABSTRACT
OBJECTIVE:
To compare the diagnostic value of high-k V X-ray chest photography and chest high-resolution computed tomography( HRCT) in the diagnosis of pulmonary thesaurosis induced by dust of iron and its compounds(hereinafter called the iron pulmonary thesaurosis).METHODS:
A total of 80 workers exposed to iron oxide dust in a magnetic material factory were collected as the study subjects by convenience sampling method,and they were examined with high-k V X-ray chest photography and HRCT. Differences between the two methods in the diagnosis of iron pulmonary thesaurosis were compared.RESULTS:
Of the 80 workers,only 5 of them(6. 2%) showed no abnormal changes in chest HRCT,others showed varying degrees of diffuse distribution of air-cavity nodules and ground-glass lesions. High-k V X-ray chest photography and chest HRCT diagnosis of iron pulmonary thesaurosis accounted for 8. 8%( 7/80) and 37. 5%(30/80) with extreme mild degree,and 21. 3%(17/80) and 26. 3%(21/80) with mild degree respectively. The diagnostic rates for iron pulmonary thesaurosis were 30. 0%( 24/80) and 63. 8%( 51/80),respectively. There was consistency between the two methods for the diagnosis of iron pneumoconiosis( Kappa = 0. 411,P < 0. 01). The chest HRCT has a higher diagnostic classification and diagnosis rate compared with the high-k V X-ray chest photography( P <0. 01).CONCLUSION:
s The chest HRCT has a higher diagnostic grade and higher diagnostic rate for lung siderosis compared with the high-k V X-ray chest photography,which is helpful for the early diagnosis of the disease.
