目的：探讨数字化X线摄影(DR)双能量减影技术(DES)技术在甲状腺肿合并气管软化诊断中的应用价值。方法：回顾性分析对47例经手术证实甲状腺肿合并气管软化的患者所做的X线气管软化试验，调取DR组与DES组图像，由甲、乙两名医生分别对两组气管受压最窄处管径差进行测量，并对其进行统计分析。结果：通过对DES图像组分析，得出的结果准确率明显高于DR组，两组间的结果有显著性差异。通过DR法与DES法测量出的管径差其差异具有统计学意义(t＝2.366，P＜0.01)。甲、乙两医生对DR法、DES法结果具有很好的一致性。结论：DES结合瓦-米(V-M)试验摄片为甲状腺肿患者术前评估有无气管软化风险及程度提供了可靠依据。

Objective: To discuss the diagnostic value of DR dual-energy subtraction in tracheomalacia in patients with large goiter to increase the diagnosis rate. Methods:Retrospective analysis X-ray tracheomalacia test by 47 patients who were confirmed by operation, were with goiter complicated by tracheomalaciaof in our hospital from 2007 January to 2013 January.To obtain DES group and the conventional DR photos , two doctors in the two groups respectively, tracheal compression the narrowest diameter difference measurement do comparative analysis. Using SPSS 18 statistical software for statistical analysis, correlation test between groups using Pearson test, compared with paired t test. Results:The image informations were analysised by doctor A and B, in the DES image group, the diagnostic accuracy of the result was significantly higher than that of the DR group,The result in the two groups has significant statistical difference. A doctor size difference by DR method and DES method to measure the diameter difference was statistically significant, B doctor size difference by DR method and DES method to measure the diameter difference was statistically significant(t=2.366,P<0.01).In the same DR method, the measurement results had no significant statistical ,in the DES method also had no statistical difference. Correlation analysis results show that:the two doctors measured data for the DR method, DES method examination has very good consistency. Conclusion:DES combining with V-M test provides reliable basis for patients with goiter in preoperative evaluation the risk and degree of softening trachea.
