BI-RADS 4类乳腺癌的超声图像特征分析

Ultrasound images of BI-RADS category 4 breast cancer

目的:回顾性分析乳腺影像报告和数据系统(Breast Imaging Reporting and Data System,BI-RADS)4类乳腺癌的超声图像特征,以提高不典型乳腺癌的超声诊断率。方法:收集5年中随访的138例超声诊断为BI-RADS 4类乳腺癌的患者,均经手术后病理学检查证实,比较超声图像分型与病理分型结果。结果:138例超声诊断的BI-RADS 4类乳腺癌中,4A类59例、4B类28例、4C类51例,与病理分型结果比较差异无统计学意义。4A与4B/4C类型的声像图特征差异有统计学意义(P<0.05)。结论:超声波检查对提高早期BI-RADS 4类乳腺癌诊断率有一定的价值。

Objective:To analyze the ultrasound features of Breast Imaging Reporting and Data System (BI-RADS)category 4 breast cancer,and to improve the diagnostic accuracy of atypical breast cancer by ultrasound.Methods:A total of 138 cases with ultrasound-diagnosed BI-RADS category 4breast cancer in 5-year follow-up were collected and confirmed by surgery and pathology. The ultrasound classification was compared with pathological results.Results:Among 138 cases of BI-RADS category 4 breast cancer diagnosed by ultrasound,there were 59 classified as 4A,28 as 4B and 51 as 4C.There was no significant difference between ultrasound classification and pathological results.But the ultrasound features between 4A and 4B/4C were significantly different (P<0.05).Conclusion:Ultrasound could improve the diagnosis of early BI-RADS category 4 breast cancer.
