Feasibility of cone-beam breast CT-guided puncture of different phantoms simulating biopsy of breast tumor / 中国介入影像与治疗学

ABSTRACT

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.
