目的:就胸部常规CT平扫加分段高分辨CT与DR对早期矽肺的诊断价值进行研究。方法:选取2009年9月至2013年9月经我院初诊的75例早期矽肺患者,分别进行X线机扫描和螺旋CT扫描。结果:本组75例早期矽肺患者中有70例经CT显示出现了直径<10mm、分布密集、且多发的小矽结节,而DR扫描只显示出现了45例,两者之间存在着较为明显的差异,具有统计学意义(P<0.05)。CT扫描检出了65例直径>10mm的团块和融合结节,而DR扫描只检出40例,两者之间存在着较为明显的差异,具有统计学意义(P<0.05)。结论:胸部常规CT平扫加分段高分辨CT对矽肺的诊断价值较高,尤其是对早期矽肺的诊断更具有重大意义。
OBJECTIVE: To study the diagnostic value of conventional chest CT scan plus segmental high resolution CT and DR in early silicosis. Methods: From September 2009 to September 2013, 75 patients with early silicosis who were newly diagnosed in our hospital were selected for X-ray and spiral CT respectively. Results: Seventy-five patients with early silicosis in this group showed 70 cases of small silicon nodules with diameter less than 10mm, dense distribution and multiple lesions, while DR scan showed only 45 cases, there was more between them Significant differences were statistically significant (P <0.05). There were 65 cases (> 10mm in diameter) of clumps and fusion nodules detected by CT scan, but only 40 cases were detected by DR scan. There was a significant difference between them (P <0.05). Conclusion: The diagnostic value of routine thoracic CT plus segmental high resolution CT in silicosis is higher, especially for the diagnosis of early silicosis.
