多层螺旋CT在活动性菌阴肺结核诊断中的价值

目的分析活动性菌阴肺结核的螺旋CT表现,探讨螺旋CT在活动性菌阴肺结核的诊断价值。方法回顾性分析196例多层螺旋CT诊断活动性菌阴肺结核的CT表现,统计、分析入选病例的CT影像资料。结果 182例确诊为活动性菌阴肺结核(A组),准确率(92.9%):"树芽征"115例(63.2%),"腺泡结节"130例(71.4%),"磨玻影"81例(44.5%),"空洞"35例(19.2%);14例经临床诊治,排除活动性菌阴肺结核诊断(B组):"树芽征"3例(21.4%),"腺泡结节"3例(21.4%),"磨玻影"2例(14.3%),空洞3例(21.4%)。结论在多层螺旋CT诊断中,"树芽征"、"腺泡结节"、"磨玻影",结合肺部其它病灶的形态、分布特点,可以提高活动性菌阴肺结核诊断的准确率。

The Value of Multislice CT in the Diagnosis of Pulmonary Tuberculosis in the Activity of Bacteria Yin

Objective Analysis of active culture negative helical CT pulmonary tuberculosis, Explore the value of spiral CT in the diagnosis of active culture negative tuberculosis. Methods The retrospective analysis of 196 cases of negative pulmonary CT findings of multislice spiral CT diagnosis of active bacteria, Statistics, analysis of selected cases of CT image data. Results Culture negative of 182 cases diagnosed with active tuberculosis （group A）, Accuracy rate （92.9%）： ＂The trees bud＂ 115 cases （63.2%）,130 cases （71.4%） of＂The acinar nodules＂, ＂Ground glass shadow＂ of 81 cases （44.5%）, ＂Hole＂ in 35 cases （ 19.2%）： 14 patients with clinical diagnosis and treatment, Exclude active culture negative tuberculo- sis diagnosis （group B）： ＂The tree bud＂ 3 cases （21.4%）, ＂The acinar nodules＂ in 3 cases （21.4%）, ＂Ground glass shadow＂ of two cases （14.3%）, ＂Hole＂ in 3 cases （21.4%）. Con- clusion For multislice CT diagnosis, ＂The trees bud＂, ＂The acinar nodules＂, ＂＇Ground glass shadow＂, Combined with other lesions of the lung morphology, distribution characteristics, Can improve the diagnostic accuracy of the active culture negative tuberculosis.
