目的：探讨超声弹性成像（UE）-超声弹性应变率比值（SR）法与 X 射线钼靶对乳腺影像报告和数据系统（BI-RADS）Ⅳ级合并乳腺癌诊断的相关性。方法选择2013年1月至2015年6月该院手术切除并经病理学证实的乳腺恶性肿瘤患者60例，其X射线钼靶BI-RADSⅣ级及以上，对60例患者的UE评分及SR进行回顾性分析，并对SR值与X射线钼靶分级进行相关性分析。结果60例患者中，BI-RADSⅣ、Ⅴ、Ⅵ级平均UE评分/平均SR值结果分别为（4.15±0.15）分/3.09±0.14、（4.40±0.09）分/3.41±0.11、（4.85±0.15）分/3.88±0.12；BI-RADSⅣ～Ⅵ级间仅 BI-RADSⅣ级平均UE评分、平均SR与Ⅴ级比较，差异无统计学意义（P＞0.05）；SR值与BI-RADSⅣ～Ⅵ级呈正相关（r=0.086、0.154、0.282， P＜0.05），且相关系数随等级上升而增大。结论 SR值与BI-RADS分级有较高相关性，二者联合应用对BI-RADSⅣ级及以上肿块有较高诊断价值。

Objective To investigate the correlation between the ultrasound elastography strain ratio (UE-SR) method and molybdenum target X-ray mammography for diagnosing the grade Ⅳcomplicating breast cancer. Methods 60 cases of breast imaging reporting and data system(BI-RADS) gradeⅣor more were selected from the patients with malignant breast tumor treat-ed by operation resection and confirmed by pathology in our hospital from Jan. 2013 to Jun. 2015 and their UE scores and SR re-sults were retrospectively analyzed. Furthermore the correlation of SR value and molybdenum target grade was analyzed. Results Among 60 cases,the average UE scores and SR values of BI-RADS gradeⅣ,Ⅴ,Ⅵwere(4.15±0.15) points/(3.09±0.14),(4.40± 0.09) points/(3.41±0.11) and (4.85±0.15) points/(3.88±0.12) respectively. The average UE scores and SR values had no statis-tical differences only between the BI-RADS gradeⅣand BI-RADS gradeⅤ(P>0.05). The SR value had a positive correlation with the BI-RADS gradeⅣ~Ⅵ(r=0.086,0.154,0.282,P<0.05),moreover the correlation coefficient was increased with the grade increase. Conclusion SR has higher correlation with BI-RADS grade. Their combination application has higher diagnostic value for diagnosing the mass with BI-RADS gradeⅣor more.
