螺旋CT在矽肺早期诊断中的价值

Clinical Values of Spiral CT in the Early Diagnosis of Silicosis

目的探讨螺旋CT在矽肺早期诊断中的价值,为矽肺的早期诊断及矽肺患者合并症、并发症的早期诊断提供依据。方法随机选取2010年1月—2011年12月来泉州市第一医院行矽肺普查的300例人员为研究对象,分别行CT和X线检查,比较分析CT检查和X线检查在不同分期矽肺检出率及合并症的检出率。结果 CT检查共确诊矽肺患者83例,检出率为27.67%,显著高于X线检查组16.67%(P<0.05),其中经CT检查确诊Ⅰ期矽肺41例,检出率为13.67%,显著高于X线检查组5.00%(P<0.05),两组Ⅱ、Ⅲ期矽肺检出率比较差异无统计学意义(P>0.05);CT检查确诊病例合并症45例,检出率为16.67%,显著高于X线检查组9.67%(P<0.05)。结论螺旋CT更清晰地显示小结节、肺气肿、小叶间隔增厚、纤维化及其他病变,在矽肺早期诊断中有十分重要的意义。

Objective This paper will make a general review on the clinical values of spiral CT in diagnosis of silicosis thereby providing a foundation for the early diagnosis of silicosis and its complication.Methods Randomly select 300 cases with silicosis census in the first of QuanZhou Hospital from January 2010 to December 2011,which were performed CT and X-ray examination,comparative analysis the detection rate different stages of silicosis with CT and X-ray examination,and the detection rate of its complication with two way.Results In CT examination,83 patients were diagnosed with silicosis,the detection rate was 27.67%,significantly higher than the X-ray examination group 16.67%(P < 0.05),which I stage confirmed by CT examination of 41 cases of silicosis,the detection rate was13.67%,significantly Higher than the X-ray examination group 5.00%(P <0.05),two groups II,III stage prevalence of silicosis was no significant difference(P > 0.05);In CT examination 45 patients were diagnosed with silicosis complication,the detection rate was 16.67%,significantly higher than the X-ray examination group 9.67%(P<0.05).Conclusion Spiral CT can display distinctly The features including nodules,thickening of interlobular septum,emphysema,diffuse fibrosis and other lesions.It is of great importance to the early diagnosis of silicosis.
