摘　　要：因职业环境造成的尘肺常见有矽肺、煤尘肺和石棉肺等,病理改变主要为结节和纤维化。尘肺的影像学检查方法有平片和CT,高分辨率CT、多层螺旋CT及其后处理技术更有利于观察细微病变,适用于尘肺早期诊断。多层螺旋CT功能成像可进一步了解尘肺病人肺功能的改变。Long-term exposure of the human body to powder-dust environment commonly results in pneumoconiosis,such as silicosis,coal worker＇s pneumoconiosis and asbestosis.The pathological features of pneumoconiosis include lung＇s nodules and fibrosis.Plain film and computed tomography（CT） are the main imaging modalities for detecting pneumoconiosis,especially the high-resolution CT（HRCT）,multi-detector row CT（MDCT） and related post-processing techniques are helpful in detecting the tiny pathological manifestations of pneumoconiosis so as to make early diagnosis.Furthermore,the functional MDCT could comprehensively assess the pulmonary physiological functions of the patient with pneumoconiosis.
