摘　　要：目的对比分析不同体模模拟经锥光束乳腺CT(CBBCT)引导下乳腺肿物穿刺活检的可行性。方法在CBBCT引导下分别对不同体模(硅胶乳腺、煮熟土豆、圆形茄子和芒果)深浅部位的靶目标(腊肠块模拟肿瘤)进行穿刺活检,统计其准确率及成本。结果同一体模深部与浅部穿刺准确率差异均无统计学意义(P均>0.05)。硅胶乳腺穿刺准确率为92.50%(37/40),土豆为81.25%(78/96),茄子为72.92%(70/96),芒果为61.54%(32/52)。结论CBBCT引导下体模穿刺活检的准确率较高,以煮熟土豆性价比最高。Objective To observe the feasibility of cone-beam breast CT(CBBCT)-guided puncture of different phantoms simulating biopsy of breast tumor.Methods Under the guidance of CBBCT,the superficial and deep targets(dachshund)of different phantoms(silicone breast,boiled potato,round eggplant,mango)were punctured and biopsied,respectively.The accuracy and cost of different phantoms were calculated.Results The accuracy of deep and shallow location of the same phantom was not significantly different(all P>0.05).The accuracy of silicone breast,boiled potato,round eggplant and mango was 92.50%(37/40),81.25%(78/96),72.92%(70/96)and 61.54%(32/52),respectively.Conclusion The accuracy of CBBCT-guided puncture of different phantoms simulating biopsy of breast tumor was high.Boiled potato was the most cost-effective phantom.
