常规超声对乳腺癌恶性征象的探讨

Discussion on Routine Ultrasound for Breast Malignancy Signs

目的探讨常规超声对乳腺癌恶性征象的价值。方法以近1年我院收治的、超声检查最大直径均<10 mm的乳腺肿块患者为研究资料,总结乳腺良、恶性肿块的声像特点以及早期乳腺癌可能较早出现的恶性征象。结果良性组的超声显像为病灶形态规则、边界清晰、内部回声较为均匀,与恶性组的超声显像表现差异有统计学意义(P<0.05)。本组研究乳腺癌早期表现为形态不规则或纵横比>1的比例最高(100%),其次为微小钙化(50.79%),后方衰减(14.29%),异常血流(9.52%)。结论掌握乳腺癌的恶性征象及早期乳腺癌较早出现的恶性特征,有助于提高小乳腺癌的诊断准确度。

Objective To investigate the value of conventional ultrasonography in breast cancer of malignant signs. Methods Nearly a year of our hospital,ultrasound were less than 10 mm diameter breast lumps for research materials,summarized the acoustic image characteristics of benign and malignant breast tumors and malignant signs of early breast cancer early. Results The ultrasonography of benign group rules for lesions form,clear boundary,internal echo was relatively uniform,with the ultrasonic imaging performance of the malignant group there were significant differences（P〈0.05）. Study of early breast cancer of irregular shape and aspect ratio greater than 1 largest percentage（100%）,followed by tiny calcification（50.79%）,rear attenuation（14.29%）,abnormal bleeding（9.52%）. Conclusion Mastering the malignant signs of breast cancer and malignant characteristics of early breast cancer earlier appear help to improve the diagnostic accuracy of breast cancer.
