螺旋CT及高KV摄影在煤工尘肺诊断中的价值

目的：评价螺旋CT及高KV摄影在煤工尘肺诊断中的价值。方法分析52例煤工尘肺的螺旋CT表现及高KV摄影胸片征象。结果螺旋CT检查的52例中有31例出现散在的0.2 cm~0.9 cm圆形结节影，大于1.0 cm的大结节有16例，35例患者有不同程度肺气肿，14例分别患有新老肺结核灶，39例有不同组的淋巴结肿大或钙化。结论螺旋CT在显示煤工尘肺直接征象和间接征象上较常规胸片敏感，可以弥补X线平片的许多不足，有利于煤工尘肺的正确诊断和鉴别诊断，特别有利于煤工尘肺的早期诊断。

Values of spiral CT and high KV Photography in diagnosis of coal Miners pneumoconiosis

Objective：To evaluate the diagnostic value of spiral CT and high KV photography in coal miners pneumoco-niosis. Methods：Chest radiographic and spiral CT images were analyzed retrospectively in 52 cases of coal miners pneurno-coniosis confirmed by clinic and radiography. Results：Scattered round nodules were seen with diameters of 0. 2cm-0. 9cm in CT in 31 case and nodules over 1. 0cm in 16 cases. Other findings in CT were as follows：emphysema in 35 patients,tu-berculosis in 14 patients,and lymph node enlargement or calcification in 39 cases. Conclusion：Spiral CT which comparison with plain radiography is proven to be a relatively precise examination method in the characterization of direct and indirect signs of coal miners pneumoconiosis,and can help radiologists to avoid mistakes and achieve accurate diagnosis.
