16层螺旋CT导引下孤立性肺结节穿刺活检

目的:评价并比较16层螺旋CT与单螺旋CT导引下孤立性肺结节穿刺活检的诊断价值及应用的安全性。方法:在16层螺旋CT、单螺旋CT导引下分别对50例肺孤立性结节穿刺活检,对采集的标本行细胞学或病理学检查,术后行CT扫描明确是否有气胸、出血等并发症,分析操作时间、取材准确性及并发症出现率。结果:16层CT穿刺活检组50例中取得满意组织并确诊46例,穿刺平均时间22.8min,并发症出现率8%;单螺旋组50例中取得满意组织并确诊37例,穿刺平均时间35.6min,并发症出现率12%;在不同CT导引下穿刺取材时间及取材准确性比较有统计学意义(P<0.05),并发症出现率无统计学意义(P>0.05)。结论:16层螺旋CT为穿刺定位取材提供了更多信息,16CT定位下的穿刺活检成功率和准确率较高,可作为孤立性肺结节定性诊断的首选方法。

16-slice spiral CT guided percutaneous needle biopsy of solitary pulmonary nodule

Objective:To evaluate and compare the diagnostic value and application safety of 16-slice Spiral CT or single CT guided percutaneous needle biopsy of solitary pulmonary nodule(SPN).Methods:50 cases SPN were performed 16-slice CT or single CT guided percutaneous needle biopsy respectively.The samples were detected by cytological and pathological measures.CT scan was performed after biopsy to observe aeropleura and hemorrhage and to analyze operating time,accuracy of samples,and complication.Results:Among 50 cases of 16-slice group,46 cases were final diagnosis.Average time of biopsy was 22.8 minutes.Frequency rate of complication was 8%.Among single group,37 cases were final diagnosis.Average time of biopsy was 35.6 minutes.Frequency rate of complication was 12%.The compare of time and accuracy of samples in different CT guided percutaneous needle biopsy was of statistical siynificance(P<0.05) while that of comp lication occurence no statistical significance(P>0.05).Conclusion:More information was provided by 16-slice Spiral CT.16-slice spiral CT guided percutaneous needle biopsy had higher successful rate and accurate rate,it shoud be the leading final diagnosis choice of SPN.
