摘　　要：目的比较在CT与B超引导下经皮肺穿刺活检的特点并分析二者临床价值及安全性。方法选取2003年5月～2006年10月肺内占位性病变患者93例,分为2组。超声能探及异常回声且病灶距胸壁<2cm为B超组,41例,其中男性30例,女性11例,年龄21～77岁;超声不能探及异常回声或病灶距胸壁>2cm为CT组,52例,其中男性34例,女性18例,年龄42～75岁。比较两组穿刺活检的确诊率及并发症发生率。结果CT及B超引导下经皮肺穿刺活检的确诊率分别为98%及100%,CT及B超引导下经皮肺穿刺活检的并发症发生率分别为13.5%及4.5%,两者比较差异有统计学意义(P<0.05)。结论B超引导下经皮肺穿刺活检的确诊率高,并发症低,操作迅速。但B超不能穿过空气,对距胸壁>2cm的病灶不宜选用,宜选用CT引导。Objective To compare the characteristics of percutaneous lung biopsy under guiding of CT or ultrasonography. Methods In ultrasonography group there were 41 patients whose abnormal echo of the lung focus had been showed by ultrasonography and the distance of focus to the chest wall were less than 2 cm. In CT group 52 patients whose lung focus were located more than 2 cm away from the chest wall. The diagnosis rate and incidence rate of complication were compared among two groups. Results The diagnosis rates in CT group and ultrasonography group were 98 % and 100 % respectively. The incidence rates of complicating diseases in the patients of CT group and ultrasonography group were 13.5 % and 4.5 % respectively, and there were significant differences between 2 groups （P 〈 0.05）. Conclusion The characteristics of lung biopsy under guiding of ultrasonography are higher in diagnosis rate,lower in incidence rate of complications and can be performed rapidly. But the ultrasound can not cross over the air,thus the lung biopsy under guiding of CT should be selected for the lung focus located away from the chest wall more than 2 cm.
