目的：探讨三维标测穿刺活检的临床应用价值。方法选择104例经临床及多层螺旋CT （MSCT）平扫、增强难以确诊，且有肺部局限性肿块患者随机分为两组，研究组采用MSCT立体定位引导下三维标测穿刺仪活检；对照组采用CT横断面图像定位引导下常规穿刺针活检。比较两组一次进针成功率、重复进针率、诊断正确率、并发症发生率及穿刺精确度分级。结果研究组一次进针成功率高于对照组，差异有统计学意义（P＜0.01）；研究组重复进针率及并发症发生率低于对照组，差异有统计学意义（P＜0.05）；研究组穿刺精确度分级高于对照组，差异有统计学意义（P＜0.01）；两组诊断正确率比较差异无统计学意义（P＞0.05）。结论 MSCT引导下三维标测穿刺活检技术明显提高了一次进针成功率与穿刺精确度分级，降低了重复进针率及并发症发生率。

Objective To investigate the clinical application value of three-dimensionally (3D)-mapped puncture biopsy .Methods A total of 104 patients were recruited as the study subjects and were randomly divided in-to two groups.MSCT 3D-positioning and 3D-mapped puncture device were used in the study group , while CT cross-sectional image positioning plus conventional puncture needle was used in the control group .The success rate at one time, repeatedly inserting needle rate , diagnostic accuracy , complication rate and puncture accuracy grading were compared between the two groups .Results The success rate at one time was significantly higher , while the rate of repeatedly inserting needle and complication rate were significantly lower in the study group than those in the control group(P<0.05).In addition, puncture accuracy grading in the study group was also increased significantly than that in the control group ( P<0.01 ) .However , there was no significant difference in the diagnostic accuracy between the two groups(P>0.05).Conclusion Compared with the conventional puncture , 3D-mapped puncture has higher one-time success rate and puncture accuracy grading and lower complication rate .
