摘要
目的:探讨超声自动乳腺容积扫描(ABVS)对乳腺肿块良恶性鉴别诊断的价值。方法:回顾性分析93例患者120个乳腺肿块术前ABVS影像学资料,并与其X线钼靶成像影像学资料进行对比研究,所有肿块均有术后病理结果。结果:ABVS与X线钼靶对乳腺肿块总病灶检出率分别为95%(114/120)、80%(96/120),两者间比较有统计学意义(P<0.05);恶性肿块中两者检出分别为98.3%(58/59)、83.1%(49/59)(P<0.05);良性肿块中两者检出分别为91.8%(56/61)、77.0%(47/61)(P<0.05)。对小病灶两者检出率分别为91.8%(67/73)、79.5%(58/73)(P<0.05);两者对小病灶恶性肿瘤检出率分别为91.4%(32/35)、80%(28/35)(P<0.05)。ABVS冠状面"汇聚征"在恶性和良性肿块中出现率分别为89.7%(52/58)、3.6%(2/56)(P<0.01);小病灶恶性和良性肿块的"汇聚征"的出现率分别为91.4%(32/35)、5.3%(2/38)(P<0.01)。结论:ABVS系统提供乳腺肿块全方位的影像学评估信息,较X线钼靶检查具有更高的病灶检出率及准确性,其"汇聚征"可作为鉴别肿块良恶性的特征性指标。
Objective： To assess the value of automated breast volume scanner（ABVS） for the diagnosis of benign and ma- lignant breast masses. Methods： ABVS images and molybdenum X-ray imaging information of 93 patients, 120 breast masses were analyzed retrospectively. All the masses had pathological findings after operations. Results： Compared total lesion detec- tion rate, ABVS relevance ratio was 95%（114/120）. Molybdenum X-ray relevance ratio was 80%（96/120）, it had statistical sig- nificance （P〈0.05）. Compared relevance rate of malignant breast tumors, ABVS relevance ratio was 98.3%（58/59）, molybdenum X-ray relevance ratio was 83.1%（49/59）, it had statistical significance（P〈0.05）. Compared relevance rate of benign masses, AB- VS relevance ratio was 91.8%（56/61）, molybdenum X-ray relevance ratio was 77.0%（47/61）, it had statistical significance （P〈 0.05）. There were 35 malignant lesions less than 2 centimeter. ABVS examined 32 lesions, relevance ratio was 91.4%. Molybdenum X-ray examination found 28 lesions, relevance ratio was 80%, it had statistical significance （P〈0.05）. Occurrence rate of masses in the coronal section of ABVS presented with ＂crater＂ sign was 89.7%（52/58）, whereas it was 3.6%（2/56） in molybdenum X-ray. The detection rate of malignant lesions of less than 2 centimeter presented with ＂crater＂ sign was 91.4% （32/35）, whereas it was 5.3% in benign lesions. ＂Crater＂ sign are specific indicators for differentiation between malignant and benign breast tumors. Conclusion： ABVS system provides the omni-directional imaging breast masses of information. Compared with molybdenum X-ray, ABVS imaging system provides much more useful information on lesions with a higher detection rate and accuracy. The ＂crater＂ sign can serve as indicators of differential characteristics between malignant and benign masses.
