摘　　要：我们回顾性细致分析49例确诊尘肺患者多层螺旋CT(MDCT)扫描图像,探讨其细微影像表现及解剖优势分布特征。本组尘肺MDCT表现以圆形小阴影p及不规则小阴影s为主,大阴影和进行性块状纤维化(PMF)病灶较少见。圆形小阴影及不规则小阴影在双肺的分布有明显差别(P<0.01),最常见的p影多分布于左肺上叶、下叶及右肺上叶;s影多分布于左肺上叶和双肺下叶。尘肺大阴影以两肺上叶分布为主,PMF则多表现为同时累及双肺的上、下叶。结果表明:MDCT能够反映尘肺的细微表现特征及其优势解剖分布,有利于疾病的早期诊断和准确分期。In order to investigate the fine distinction of the tomographic images and the dominant anatomic distributions,we carefully reviewed and analyzed the features and predominant anatomic distribution of forty-nine pneumoconiosis patients with confirmed diagnosis on multi-detector row CT（MDCT）.It was found that the round and small opacity p and irregular small opacity were mostly shown in the MDCT features of pneumoconiosis,while the large opacity and progressive massive fibrosis（PMF） were less frequently depicted in the MDCT.Distributions of round and small opacity and irregular small opacity in the six lung lobes were significantly different（P0.01）.The most common p opacity was significantly seen in the upper and lower left lungs as well as in the upper right lung;s opacity was in the upper left lung as well as lower left and right lungs.The large opacity commonly distributed in upper left and right lungs,while the PMF was often shown in both of two lungs.The results demonstrated that the MDCT could be an effective modality for detecting tiny lesions and anatomic distribution of pneumoconiosis,and it would be helpful for early diagnosis and accurate staging of the pneumoconiosis disease.
