【摘要】Objective To explore the early coal pneumoconiosis patients with

HRCT

staging

and

pulmonary

function

abnormali-ties

indicators ,provide an objective basis for clinical diagnosis and treatment early pneumoconiosis .Methods Strict control of the inclusion criteria :no smoking ,no pneumonia ,no tuberculosis ,no lung cancer and no lung surgery ,as a result ,total 33 early coal pneumoconiosis patients were chosen in the study .All of them were underwent paired CT obtained at full inspiratory position .High kv chest radiography ,and pulmonary function tests at the same day .Reference to the chest X-ray pneumoconiosis classification method as pneumoconiosis HRCT staging .Analyzed the correlation between early coal pneumoconiosis with HRCT staging and the parameters ,including Forced vital capacity (FVC) ,Forced expiratory volume in 1 second(FEV1) ,FEV1/FVC ,Maximum midexpi-ratory

flow(MMEF)

,Peak

expiratory

flow(PEF) ,FEF75 ,FEF50 ,FEF25 ,Total lung capacity(TLC) ,Residual volume(RV) ,Carbon monoxide diffusion capacity(DLco) ,KCO and so on .Results HRCT could be more accurately display the shape ,size and distribu-tion of coal pneumoconiosis small nodules .There were
