ABSTRACT
Objective:
To study the practical value and imaging expression of target reconstruction technique of HRCT in the diagnosis of pneumoconiosis.Methods:
Fifty-seven cases with different level type of pneumoconiosis were first examined by routine CT scan,followed by HRCT examination at top of aortic arch,carina of trachea,3 cm below bifurcation of bronchi,and 2 cm above thd right diaphragm.Target reconstruction have been finished using the raw data stored.Results:
Target reconstruction photoimages were cleared to display the morphology of delicate lesions of pneumoconiosis(1)Nodular shape(100%).(2)Interlobular septal thickening(98.24%).(3)Lobular structure abnormality(98.24%).(4)Subpleural nodes (84.21%).(5)Centrilobular emphysema(63.15%).(6)Subpleural line(64.91%).(7)Bronchiectasis(63.15%).(8)Ground-glass opacity(35.08%).(9)Honeycombing(15.78%),and to display earlier period change details.Conclusion:
HRCT target reconstruction technique may make lesion dispaly more detail than comventional and high-resblution CT.It is reliable to display the delicate lesions of pneumoconiosis and provide more diagnostic information.
