【摘要】：目的:探讨多层螺旋CT(MSCT)图像后处理技术在经皮肺穿刺活检术中的立体定位与测量方法的可行性。方法:随机从2013年1月~12月来我院行CT引导下经皮肺穿刺活检患者中收集100例,随机分成两组,50例使用MSCT图像后处理技术立体定位法与三维标测穿刺针作为研究组,50例使用传统CT横断面定位法与现有穿刺针作为对照组,总结穿刺次数,确诊率,并发症发生率,进行统计比较。结果:研究组的穿刺次数的均数为1.11±0.33次,穿刺诊断准确率98%(49/50),并发症发生率14%(7/50);对照组的穿刺次数均数为4.26±1.86次,穿刺诊断准确率64%(32/50),并发症发生率80%(40/50);两组比较有统计学意义(P0.05)。结论:MSCT图像后处理技术引导下的立体定位,定位更全面,穿刺更安全,在选择穿刺点与穿刺路径上更科学,提高了肺穿刺的确诊率,降低了并发症的发生率,具有广阔的推广与应用价值。
[Abstract]:Objective: to investigate the feasibility of stereotactic localization and measurement of multi-slice spiral CT (MSCT) image post-processing in percutaneous lung puncture. Methods: from January to December 2013, 100 patients were randomly divided into two groups. 50 patients were treated with MSCT image post-processing stereotactic method and three-dimensional mapping puncture needle as the study group, and 50 patients were treated with the traditional CT cross-section localization method and the existing puncture needle as the control group. The number of puncture, the diagnosis rate and the incidence of complications were summarized and compared statistically. Results: the average number of puncture in the study group was 1.11 卤0.33, the accuracy of puncture diagnosis was 98% (49 鈮，
