摘要
目的:评价 CT 导引下肺内小结节灶穿刺活检对诊断的价值。材料和方法:搜集 CT 导引下肺内病变穿刺活检182例,其中46例为肺内小结节灶,结节直径5～10mm 5例,11～15mm 20例,16～20mm 21例,共49个结节行50次活检,均在 CT 导引下进行。结果:49个结节均被刺中,诊断正确率为96%。假阴性为6.9%。无假阳性,气胸发生率为12%,无1例需放置闭式引流。结论:CT 导引下肺内小结节穿刺活检正确率高,并发症少,可作为肺内孤立性小结节灶组织学诊断的首选方法。
Purpose:To evaluate the diagnostic effect of CT-guided biopsy of small pulmonary nodules.Meterials and Methods:182 cas- es of lung lesions underwent needle biopsy under CT guidance.Among them,49 nodules of 46 case were defined as small nodules(the nod- ule diameter<20ram),5～10mm(5),11～15mm(20)and 16～20mm(21).Results:All nodules were punctured precisely.The diag- nostic accuracy was 96 %,and the sensitity for diagnosis of cancer was 93.1%.The false-negative result was 6.9%,no false-poshive was found.The occurrence of pneumothorax was 12% without chest tube placement.Conclusion:CT-guided biopsy of small pulmonary nodule is a safe,accurate way for nodule's histologic diagnosis.
