超声弹性成像对乳腺增生症伴纤维腺瘤与乳腺癌BI-RADS校正价值

摘要

Objective To investigate the value of correction of ultrasound elastography strain rate ratio in BI-RADS grading of breast hyperplasia with fibroadenoma and breast cancer.Methods The data of 120 cases of hyperplasia of mammary gland hyperplasia with fibroadenoma and 120 cases of breast cancer confirmed by operation or biopsy in this hospital from January 2012 to October 2016 were analyzed retrospectively.The boundary,shape,echogenicity,aspect ratio,calcification,blood flow distribution,resistance index,BI-RADS grade,ultrasonic elastography strain ratio were analyzed.The value of correction of ultrasound elastography strain rate in breast hyperplasia with fibroadenoma and breast cancer BI-RADS grading ratio were investigated.Results There were significant differences in boundary,rear echo,aspect ratio,calcification,ultrasonic elastography strain ratio between breast hyperplasia with fibroadenoma and breast cancer (P＜0.05);There was no significant difference between the two groups about morphology and internal echo (P＞0.05);Breast hyperplasia with fibroadenoma were mainly 0-Ⅰ in blood flow distribution,RI＜ 0.7,breast cancer showed Ⅱ-Ⅲ,RI≥0.7,the difference was statistically significant (P＜0.05).Ultrasound elastography strain rate ratio improved the diagnose accordance rate of two groups after BI-RADS' classification correction.Conclusion Hyperplasia of mammary glands with fibroadenoma and breast cancer have overlapping ultrasound features.Ultrasound elastography strain rate ratio can improve the diagnose accordance rate of two groups after BI-RADS' classification correction,which has certain clinical value.%目的 探讨超声弹性成像应变率比值对乳腺增生症伴纤维腺瘤与乳腺癌BI-RADS分级的校正价值.方法 回顾性分析2012年1月至2016年10月在该院经手术或穿刺活检证实的120例乳腺增生症伴纤维腺瘤与120例乳腺癌患者资料,总结其边界、形态、内部回声、后方回声、纵横比、钙化、血流分布、阻力指数、BI-RADS分级、超声弹性成像应变率比值等特点,分析超声弹性成像应变率比值对乳腺增生症伴纤维腺瘤与乳腺癌BI-RADS分级的校正价值.结果 乳腺增生症伴纤维腺瘤与乳腺癌超声图像在边界、后方回声、纵横比、钙化、超声弹性成像应变率比值之间差异有统计学意义(P＜0.05);在形态、内部回声之间差异无统计学意义(P＞0.05);血流分布方面,乳腺增生症伴纤维腺瘤主要表现为0～Ⅰ级,阻力指数(RI)＜0.7,乳腺癌多表现为Ⅱ～Ⅲ级,RI≥0.7,差异有统计学意义(P＜0.05).超声弹性成像应变率比值对两者BI-RADS分级校正后诊断符合率有明显提高.结论 乳腺增生症伴纤维腺瘤与乳腺癌具有重叠超声表现,超声弹性成像应变率比值对两者BI-RADS分级校正后的定性诊断能力有提高,具有一定的临床价值.
