摘　　要：目的:探讨自动乳腺容积成像(ABVS)检查用于乳腺癌的临床诊断价值,以获得可靠数据为后续治疗提供影像学依据。方法:选取300例疑似乳腺癌患者,以术后病理组织检查作为金标准进行筛检试验,同时选取2名影像学医师进行乳腺影像报告和数据系统(BI-RADS)分级诊断,观察ABVS诊断与病理检查结果的一致性。结果:经过手术后病理组织检查,210例确诊为乳腺肿瘤,其中恶性肿瘤89例,占29.67%(89/300),以浸润性导管癌占比最多(42例),占47.19%(42/89);良性肿瘤者121例(占40.33%),其中以纤维腺瘤占比最多(78例),占64.46%(78/121),两者诊断一致性较好,K=0.724。自动乳腺全容积成像诊断的灵敏度为92.86%,特异度为85.56%,阳性预测值为93.75%,阴性预测值为83.70%,约登指数为0.78。结论:ABVS检查具有较高的灵敏度和特异度,筛检试验具有较好的真实性和可重复性,可为临床诊治提供可靠依据。Objective： To investigate the diagnostic value of automatic breast volume system（ABVS） for breast carcinoma in clinical practice so as to use these reliable data to provide imaging reference for further therapy. Methods： 300 patients with suspected breast cancer were selected and the postoperative pathological examinations were chosen as the golden standard to implement screening. At the same time, 2 radiologists were selected to carry out the grading diagnoses of breast imaging reporting and data system（BI-RADS） so as to observe the consistency between diagnoses of ABVS and pathological results. Results： 210 patients were diagnosed as breast tumor by the post-operative pathological examination, and these patients included 89 malignant tumor（29.67%, 89/300）. In these malignant cases, there were 42 cases were infiltrative ductal carcinoma, and its rate was 47.19%（42/89）. Besides, there were 121 cases were benign tumor（40.33%）, and the rate of patients with fibrosum adenoma（78 cases） was the highest in the 121 cases（64.46%, 78/121）. And the diagnostic consistency of them was preferably（K=0.724）. The sensitivity and specificity of ABVS in diagnosing breast carcinoma were 92.86% and 85.56%, respectively. Its positive predictive value and negative predictive value were 93.75% and 83.70%, respectively. And the Youden index was 0.78. Conclusion： ABVS has relatively high sensitivity and specificity, and the screening test has good authenticity and reproducibility. Therefore, it can provide a reliable basis for clinical diagnosis and treatment.
