| 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 "spiculaiton", "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. |
