超声诊断BI-RADS4级乳腺病灶

Ultrasonic features of BI-RADS 4 level breast lesions

目的探讨恶性超声征象诊断BI-RADS 4级乳腺病变的价值。方法回顾性分析术前应用超声诊断为BI-RADS 4级的乳腺病变患者338例(405个病灶),将超声所见与手术病理结果进行对照。结果 "毛刺征"、"后方回声衰减"及"RI值≥0.7"为诊断特异度较高的超声征象,对乳腺癌的诊断特异度分别为98.36%(299/304)、90.12%(274/304)和86.24%(262/304)。结论 "毛刺征"、"后方回声衰减"及"RI值≥0.7"为特异度较高的超声征象,当出现这3个征象时,BI-RADS 4级评分倾向于4C级。

Objective To investigate the value of ultrasound in diagnosis of BI-RADS 4 level breast lesions. Methods Three hundred thirty-eight patients with 405 breast lesions underwent ultrasound examination, and the lesions were diagnosed as BI-RADS 4 level. The results were compared with surgery and pathological findings. Results The diagnostic specificity of ＂spiculation＂, ＂posterior echo attenuation＂ and ＂RI≥0.7＂ to BI-RADS 4 level breast cancer was 98.36% （299/ 304）, 90.12% （274/304） and 86.24% （262/304）, respectively. Conclusion The findings of ＂spieulaiton＂, ＂posterior echo attenuation＂ and ＂RI≥0. 7＂ are the most specific ultrasonic signs of BI-RADS 4 level breast lesions that indicating the grading of BI-RADS 4 level to 4C.
