目的分析33例陶瓷矽肺大阴影的X线片与同期HRCT表现,研究诊断的优越性。方法运用高仟伏摄片和HRCT技术。结果33例矽肺大阴影2种检查方法对比表明,HRCT能清楚显示大阴影的细微结构变化,如灶周结节、肺气肿、纤维索条影以及血管、支气管特征变化。结论HRCT显示陶瓷矽肺大阴影的形态学特征优于X线片,在肺结核、肺癌等鉴别诊断方面具有很大价值。
Objective To analyze the radiographic findings of 33 cases of silicosis with large shadow and HRCT in the same period to study the superiority of diagnosis. Methods High-kV radiography and HRCT techniques were used. Results Comparison of the two examination methods of 33 cases of large silicosis shows that HRCT can clearly show the microscopic structure changes of large shadow, such as nodules, emphysema, fibrillation and changes of blood vessel and bronchus. Conclusion HRCT shows that the morphological features of the large shadow of ceramic silicosis are better than that of X-ray, which is of great value in the differential diagnosis of tuberculosis and lung cancer.
