摘要
目的比较螺旋CT与直接数字化X线摄影对矽肺病灶诊断的差异。方法回顾性分析90例矽肺患者螺旋CT和数字化X线摄影的影像学表现。结果螺旋CT检查与常规数字X线摄影检出结果在对小结节、大阴影病灶发现率,判断肺间质改变、肺气肿、并发症、淋巴结肿大及钙化等方面差异均有统计学意义(P<0.05)。结论螺旋CT矽肺诊断符合率明显高于数字化X线摄影,在正确判断矽肺部病变程度、范围及并发症等方面具有明显优势;但整体形态显示等方面,螺旋CT稍逊;两者结合有助于矽肺的正确诊断。
Objective To compare the difference of spiral CT and digital X-ray photography in the diagnosis of silicosis. Methods Data of imaging findings from 90 cases with silicosis underwent both spiral CT and digital X-ray photography were retrospectively analyzed. Results The imaging findings reported by spiral CT and conventional digital X-rays were significantly different in lesion detection rate in showing small nodules in the large shadow, and in determining the changes in pulmonary interstitial emphysema, complications, lymph node enlargement and calcification （P^0. 05）. Conelasion The accordance rate for diagnosing silicosis is higher reported by spiral CT than that by digital X-ray photography. Spiral CT is superior in eveluating the severity of silicosis, extent and complications to digital Xray photography, but not in the overall display. Combined examination of both can contribute to correct diagnosis of silicosis.
