自动乳腺全容积成像技术诊断乳腺肿块的价值

目的探讨自动乳腺全容积成像技术（ABVS）在乳腺肿块中的应用价值。方法选择乳腺肿块患者100例，共114个病灶，分别采用二维、弹性成像、ABVS诊断，并与病理结果对照。结果良性组42例52个病灶，其中导管内乳头状瘤3个，纤维腺瘤29个，囊肿4个，乳腺炎3个，纤维囊性乳腺病13个。恶性组58例62个病灶，其中转移癌1个，导管内原位癌2个，浸润性导管癌56个，黏液腺癌2个，腺癌1个。52个良性病灶，二维超声诊断正确40个，62个恶性病灶，二维超声诊断正确49个，共误诊25个，二维诊断乳腺肿瘤的敏感度为79．0％（49／62），准确性为78．1％（89／114），特异性为76．9％（40／52）。52个良性病灶，弹性成像诊断正确41个，62个恶性病灶，弹性成像诊断正确50个，共误诊23个，弹性成像诊断乳腺肿瘤的敏感性80．6％（50／62），准确性79．8％（91／114）％，特异性78．8％（41／52）％。52个良性病变，ABVS诊断正确45个，62个恶性病灶，ABVS诊断正确54个，ABVS诊断乳腺肿瘤的敏感度为87．1％（54／62），准确性86．8％（99／114），特异性86．5％（45／52）。ABVS在乳腺病灶定性诊断上占有明显的优势，其诊断乳腺肿瘤的敏感度、准确性和特异性与二维及弹性成像比较差异均有统计学意义。结论自动乳腺全容积成像技术能够进行乳腺病灶定性诊断，有助于乳腺肿瘤的确诊，敏感度好，准确性与特异性优越，值得临床推广与应用。

Value of automated breast volume scanner in the diagnosis of breast mass.

Objective To investigate the application value of automated breast volume scanner （ABVS） for breast mass. Methods One hundred patients suffering from breast mass were selected in this study, involving 114 les- sions. Two-dimentional ultrasonography, elastic imaging and ABVS were used for diagnosis. The diagnostic results ob- tained above were compared with pathological results. Results In the benign group, there were 42 cases of patients and 52 lessions, including 3 lessions of intraductal papilloma, 29 of fibroadenoma, 4 of cyst, 3 of mastitis, and 13 of fi- brocystic mastopathy. In the malignant group, there were 58 cases of patients and 62 lessions, including one lesion of metastatic carcinoma, 2 of intraductal carcinoma in situ, 56 of invasive ductal carcinoma, 2 of mucinous adenocarcino- ma, and one of adenocarcinoma. Forty of the 52 benign lessions were correctly diagnosed by two-dimensional ultraso- nography, and 49 of the 62 malignant lessions were correctly diagnosed by two-dimensional ultrasonography. A total of 25 lessions were misdiagnosed. For two-dimensional ultrasonography, the sensitivity was 79.0% （49/62）, accuracy was 78.1% （89/I 14） and specificity was 76.9% （40/52）. When elastic imaging was used for diagnosis, 41 of the 52 be- nign lessions were correctly diagnosed and 50 of the 62 malignant lessions were correctly diagnosed, and a total of 23 lessions were misdiagnosed, with a sensitivity of 80.6% （50/62）, an accuracy of 79.8% （91/114）, and a specificity of 78.8% （41/52）. For ABVS,.45 of the 52 benign lessions and 54 of the 62 malignant lessions were correctly diagnosed, with a sensitivity of 87.1% （54/62）, an accuracy of 86.8% （99/I 14）, and a specificity of 86.5% （45/52）. ABVS had ob- vious advantages for qualitative diagnosis of breast lesions. Differences in the sensitivity, accuracy, and specificity be- tween ABVS and two-dimensional ultrasonography, elastic imaging were statistically significant. Conclusion Auto- mated breast volume scanner （ABVS） can be used for qualitative diagnosis of breast lessions, which is helpful for breast tumor, with good sensitivity, accuracy and specificity. It is worthy of clinical popularization and application.
