乳腺肿块的超声图像浅析

目的:探讨乳腺肿块的超声图像特征并与病理对照。材料与方法:61例乳腺肿块患者,女性,年龄19～70岁,术前均接受了B超检查,术后经病理证实,使用仪器为PHASAR-AU530,7.5MHz水囊探头。结果:从61例患者中B超查出乳腺癌38例,良性肿块23例,相应于病理结果的诊断敏感性为92.1％,特异性为86％。乳腺恶性肿块的超声图像特征是形态不规则,无包膜,边界粗糙,回声增强,内部回声多为低回声实性,后方回声衰减等,这些表现也是与良性肿块的重要区别之点。结论:综合分析各个声像图特征是鉴别良性与恶性乳腺肿块的关键。

Diagnostic Efficacy of Ultrasonography in Breast Mass: Preliminary Analysis of 61 Cases

Purpose: To explore the ultrasonographic features of breast mass and compare with pathologic diagnosis. Materials and Methods: 61 patients with breast mass, who were female and whose age ranged between 19 - 70 years, underwent the examination of B model ultrasound before the operation and were proven by postoperative pathologic diagnosis. The instrument used in this study was PHASAR - AU 530 with a 7. 5MHz water -cystic probe. Results: During ultrasound scan, 38 cases of breast cancer and 23 cases of benign mass were found from all patient with breast mass, the diagnostic sensitivity corresponding to pathologic results was 92%. The ultrasonographic features of malignant mass were found to be form irregularity, without capsule, border coarse, e-cho enhancement, posterior echo attenuation et c. These features were also important destinction from benign mass. Conclusion: Overall analysis of each ultrasonographic feature will be critical factor to distinguish malignant and benign mass in breast.
