目的 明确结核菌素试验(PPD)硬结的超声声像图特征,阐明超声在PPD硬结判定中的应用价值.方法 收集我院进行PPD检查的患者150例,同时进行PPD硬结人工判读(A组)和超声探查(B组),分析PPD硬结不同反应结果(阴性、阳性、强阳性)的超声声像图表现,检测A、B组的强阳性率.结果 超声显示PPD硬结不同反应结果(阴性、阳性、强阳性)的超声声像图表现不同.150例患者中最终确诊结核病117例,非结核病33例,B组强阳性率(81.2％)较A组(42.7％)显著升高(P＜0.05).结论 PPD硬结不同反应结果的超声声像图表现不同,相比传统人工判读对PPD硬结的判定具有更高的特异度和灵敏度,有望成为PPD硬结判读的一种高效可靠的新方法.“,”Objective To clear the ultrasonographic features of tuberculin skin test (PPD) induration,clarify the application value of ultrasound in PPD induration judgment.Methods One hundred and fifty patients from in our hospital were examined by PPD,and the PPD induration were scored relatively by artificial interpretation (group A) and ultrasound interpretation (B group),analysis the ultrasonographic features of different induration the PPD.Results (negative,positive,positive) and detect the strong positive rate of A and B group.Results The ultrasonographic manifestations showed differences of PPD induration (negative,positive,positive).117 cases were definite tuberculosis in the 150 cases and 33 cases were not tuberculosis.The positive rate of B group (81.2％) than in A group (42.7％) was significantly increased (P＜ 0.05).Conclusions Ultrasonographic manifestations shows difference of different PPD induration reaction results,compared with the traditional manual interpretation of the decision PPD induration,it shows higher specificity and sensitivity,and is expected to be an efficient and reliable new method for the diagnosis of PPD induration.
