【摘要】 目的　探讨粗切割针经皮肺穿刺活检对肺结核病的诊断价值。方法　对 38例不同形态肺结核病灶在 CT引导下穿刺的阳性率情况 ,以及穿刺标本不同检查方法的阳性率进行比较分析。结果　总阳性率为86 .8% ,其中 1结节肿块影、斑片影阳性率分别为 96 .1%、80 % ,空洞影为 5 7.1% ;2穿刺后组织学、抗酸杆菌培养、细胞学、涂片抗酸杆菌的阳性率分别为 6 5 .8%、34.2 %、33.3%、5 .2 %。结论　 CT下粗切割针穿刺活检对肺结核病是一种诊断准确性较高的检查方法 ,活检标本采用多种方法检查可提高阳性率。更多还原

【Abstract】 Objective To investigate the diagnostic value of core thick needle lung biopsy to tuberculosis.Methods The positive rate of CT-guided puncture and different study methods to puncture preparation in 38 cases varied tuberculosis were compared and analysised.Results All the positive rate was 86.8%.Among those preparations the positive rate of tubercle,spot shadow and caverna shadow were 96.1%,80% and 57.1%.The positive rate of tissue slice,antiaid bacillus cultivation,cytology and smear after puncture were 65.8%,34.2%,33.3% and 5.2%.Conclusion CT-guided core needle lung biopsy is a more sensitive diagnostic method to tuberculosis.Various study ways to biopsy preparation can improve positive rate.更多还原
