Application Value Study of Four-dimensional CT in Percutaneus Aspiration Lung Biopsy

目的探讨四维磁导航引导CT定位在经皮穿刺肺活检术中的应用价值研究。方法选取我院常规CT引导下经皮穿刺肺活检术的患者为对照组,四维磁导航引导CT定位经皮穿刺肺活检术为观察组,两组患者各30例。比较两组穿刺手术时间、并发症出现情况,分析四维磁导航引导CT定位经皮穿刺肺活检、氩氦刀冷冻治疗方面的技术优势与运用价值。结果两组均未有患者发生并发症,观察组(9.87±2.16)分钟比对照组(15.89±4.01)分钟穿刺时间短,两组数据具有统计学差异(t=7.239,P<0.05)。观察组出现一例导航工具V-TRACK信号不稳定。四维磁导航引导CT定位Multiple views手术时间较短,定位精准。结论四维磁导航引导CT定位微小病灶穿刺活检,创伤小,准确定位做到微小病灶早期发现与确诊肿瘤,获取组织学标本进行基因检测,利于在治疗的不同时期对患者进行治疗评估。

Objective To investigate the application value of Four-dimensional CT in percutaneus aspiration lung biopsy.Methods Patients with common CT guided percutaneus aspiration lung biopsy in our hospital were selected as control group and those with Four-dimensional computed tomography were seen as observation group, 30 cases in each group. Compare the piercing operation time, complication situation, technological superiority of Four-dimensional computed tomography in percutaneus aspiration lung biopsy and Ar-He cryoablation treatment of the two groups.Results No complications occurred in patients. Piercing time of observation group （9.87±2.16） rain was shorter than control group （15.89±4.01）rain, the difference was statistically significant （t=7.239,P〈0.05）. One cases showed unstable radio signal in navigation tools in observation group. Four-dimensional magnetic guidance CT positioning views multiple operation time is short, precise positioning. Conclusion Four-dimensional CT applied in percutaneus aspiration lung biopsy has smaller trauma, accurate location and can make a definite diagnosis on tumor. It is beneficial fortreatment evaluation of patients at different phases.
