煤工尘肺胸部CT检查的诊断价值

The Value of Chest Computer Tomography in Diagnosis of Pneumoconiosis in Coalminer

目的:评价胸部CT检查煤工尘肺临床诊治过程中的应用价值。方法:对71例已经确诊为煤工尘肺的患者行肺部CT检查,根据CT图像,得出各自主要征象,并做统计学计数。结果:55例以双肺弥漫分布2 mm^3 mm小结节影为主,结节融合多位于双肺上叶(尖)后段及下叶背段;9例以双肺广泛分布不规则形纤维索条影为主;7例以双肺磨玻璃影为主;57例可见纵隔淋巴结肿大伴钙化;19例可见胸膜局部增厚,8例伴有胸水;且其中13例合并肺结核,5例合并肺癌,均经临床证实。结论:煤工尘肺的CT表现典型,CT检查可作为患者确诊及定期复查的常规检查,并且对煤工尘肺合并肺结核及肺癌等合并症的发现也很有价值。

Objective： Evaluate chest computer tomography （CT） in diagnosis of pneumoconiosis in coalminer. Methods： Conduct chest CT in 71 patients who had been diagnosed as coalminer＇s pneumoconiosis. Results： 2 mm to 3 mm opaque nodules were distributed in 55 patients＇lungs. 9 patients＇lungs were full of irregular fibrotic bars. 7 patients＇ lungs were rich in ground - glass opacity. Lymph nodes＇ tumefaetion and calcification were seen in 57 patients. Partial inerassation in pleura were seen in i9 patients, with hydrothorax in 8 patients. Besides, there were 13 patients sufferring from pulmonary tuberculosis, and 5 patients with lung cancer. Conclusion： CT with typical representation, is regarded as routine examination in diagnosis and periodical countercheck in patients with pneumoconiosis, and it is also important to discover pulmonary tuberculosis and lung cancer.
