目的:探讨早期尘肺患者行影像学检查在临床诊断的意义,提高社会群众对早期尘肺的了解,做好相应的预防及治疗工作。方法:选取2013年1月~2014年1月期间我院进行常规体检的厂矿矽尘接触者50例,并设为观察组,同期选取50例健康体检者作为对照组,两组患者在一般资料上比较无统计学差异(P>0.05)。对两组患者均行螺旋CT诊断,并对诊断结果进行对比分析,了解尘肺诊断的要点。结果:观察组50例患者中,检出尘肺者20例,所占比例为40%。组间比较中,观察组患者的肺部体积为(3 698.32±572.13)cm~3;容积百分比为76.98%;对照组患者的肺部体积为(4 024.41±392.87)cm~3,容积百分比为87.53%,组间比较差异具有统计学意义(χ~2=9.239、8.728,P<0.05)。结论:早期对尘肺患者行影像学检查具有重要意义,肺部体积缩小及容积百分比减小是早期尘肺的主要诊断特征,每一位相关工作者需定期接受诊断,做到早发现早治疗,以控制病情呈进行性发展。
Objective: To explore the significance of imaging diagnosis in patients with early pneumoconiosis in clinical diagnosis, to improve the understanding of early stage pneumoconiosis among the general public and to make appropriate preventive and curative work. Methods: From January 2013 to January 2014 in our hospital for routine physical examination of silica dust exposure in 50 cases, and set the observation group, the same period selected 50 cases of healthy subjects as control group, two groups of patients in the general information There was no significant difference (P> 0.05). The two groups of patients underwent spiral CT diagnosis, and comparative analysis of diagnostic results to understand the main points of pneumoconiosis diagnosis. Results: Among the 50 patients in the observation group, 20 cases of pneumoconiosis were detected, accounting for 40%. The lung volume of the observation group was (3 698.32 ± 572.13) cm -3; the volume percentage was 76.98%; the volume of the lung of the control group was (4 024.41 ± 392.87) cm 3, the volume percentage was 87.53%. The difference between the two groups was statistically significant (χ ~ 2 = 9.239, 8.728, P <0.05). Conclusion: Early imaging of pneumoconiosis patients is of great significance. The reduction of lung volume and volume percentage are the main diagnostic features of early pneumoconiosis. Each related worker needs regular diagnosis and early detection of early treatment Control of the disease was progressive development.
