摘　　要：目的 对锥光束乳腺CT(cone-beam breast com p uted tomogra phy,CBBCT)引导定位活检图像的质量进行评价并分析如何控制图像质量。方法 回顾性随机选取我院2019年7月至2021年12月期间33例行CBBCT引导乳腺病灶定位活检的CBBCT定位活检图像,由2名有经验的放射科医生采用5分赋值法评价CBBCT引导活检的图像质量,采用Kappa检验比较两者评估结果 的一致性。结果 医生A、B分别认为有26例(78.79%)28例(84.85%)达到4分以上,定位活检图像质量符合病灶定位需求,两名医师对图像质量评估具有高度一致性(Kappa=0.712),两者差异具有统计学意义(P<0.001)。结论 CBBCT引导定位活检图像质量良好,可准确引导定位,满足医师对乳腺病灶定位需求。Objective The purpose of this study was to evaluate the image quality of cone-beam breast CT(CBBCT)-guided biopsy and analyze how to improve the image quality.Methods CBB CT-guided biopsy images of 33 patients with breast tumors were randomly selected from July 2019 to December 2019.The image quality of CBBCTguided biopsy was evaluated by 5-score assignment method by two experienced radiologists.The interobserver agreement between the two evaluation results was analyzed with Kappa test.Results There were 26 cases(78.79%)and 28 cases(84.85%)received the rating of 4 points and above by each radiologist(evaluated with 5-score assignment method).The CBBCT image quality meets the requirement for CBBCT-guided biopsy procedure.The observer agreement between the two readers was high degree(Kappa=0.712,P<0.001).Conclusion The CBBCT image quality is considered good and sufficient for CBBCT-guided biopsy procedure.
