目的探讨矽肺患者的CT诊断价值。方法随机选取2000年1月-2012年1月因矽肺就诊于我院进行治疗的患者200例,所有患者均采用X线检查及CT检查,将两组检查方法的影像学检出率以及分辨率进行对比并行统计学分析。结果 CT检查检出率为33.5%,明显优于X线检出率,CT检查Ⅰ期检出率12.5%,检出患者的平均粉尘接触时间为5.89±2.31年,分辨率明显高于X线检查,P均<0.05,差异有统计学意义。结论 CT检查能较好地提高矽肺的检出率与分辨率,有利于明确诊断矽肺以及指导治疗。
Objective To investigate the diagnostic value of CT in silicosis patients. Methods From January 2000 to January 2012, 200 cases of patients treated by silicosis in our hospital were randomly selected. All the patients were examined by X-ray and CT. The detection rate and resolution Comparative parallel statistical analysis. Results The detection rate of CT examination was 33.5%, which was significantly better than that of X-ray examination. The detection rate of phase Ⅰ in CT examination was 12.5%. The average dust exposure time was 5.89 ± 2.31 years, the resolution was significantly higher than that of X-ray Check, P <0.05, the difference was statistically significant. Conclusion CT examination can improve the detection rate and resolution of silicosis, which is helpful for the definite diagnosis of silicosis and guiding treatment.
