尘肺合并肺结核影像学研究进展

The imaging development in pneumoconiosis complicated with pulmonary tuberculosis

肺结核是尘肺严重而较为常见的合并症。本文详细概述了尘肺合并肺结核的影像学表现、好发部位、分型及不同尘肺期别和尘肺不同类型阴影合并肺结核情况。大量资料显示,胸部CT对于发现小病灶、早期诊断、显示空洞、支气管内膜结核、钙化及结核活动情况等优于胸部平片;动态观察等在尘肺合并肺结核诊断及鉴别诊断有重要意义。本文还对胸部CT,特别是螺旋CT、HRCT及图像后处理方法等在诊断尘肺合并肺结核的作用等方面进行了展望。

Pulmonary tuberculosis is a quite common and severe complication in pneumoeoniosis. This paper outlines the imaging appearance, predilection site, typing of pneumoconiosis and the TB complicating situation with different shadows of pneumoeoniosis. It is showed that thorax CT is superior to plain film in finding small lesion, early diagnosis, demonstrating cavitates, endobronchial tuberculosis, calcification and the activities of the tuberculosis, and the dynamic observation is also important in diagnosis and differential diagnosis of pneumoconiosis complicated with pulmonary tuberculosis. Additionally, the paper gives a look ahead in the role of thorax CT, especially multilayer spiral CT and image pastprocession tectmique in the diagnosis of pneumoconiosis complicated with pulmonary tuberculosis.
