超声弹性成像与乳腺BI-RADIS分级联合应用于65例病灶分析

Discussion of sonoelastography and BI-RADIS grading in diagnosis of 65 lesions

目的探讨超声弹性成像与乳腺图像和报告数据体系（BI-RADIS）联合应用在乳腺肿块良恶性鉴别诊断中的应用价值。方法对65例乳腺肿块进行二维超声及超声弹性成像检查，判断乳腺BI-RADIS分级与病灶弹性评分，并与病理结果进行对照分析。结果65例病灶中，良性28例，其中总分小于或等于6者27例；恶性37例，其中总分大于6者35例。用该标准进行诊断，准确度为95％（62／65），敏感度为95％（35／37），特异度为96％（27／28）。结论超声弹性评分与乳腺BI-RADIS分级之和大于6者恶性可能性增大，小于或等于6者良性可能性较大。超声弹性成像与BI-RADIS联合应用可更加客观地判断乳腺肿块的良恶性，对确定是否进行早期手术具有重要临床意义。

Objective To investigate the application significance of sonoelastography combined with breast imaging and reporting date system （BI-RADIS） in differential diagnosis of benign and malignant breast masses. Methods Two-dimensional ultrasound imaging and sonoelastography were performed on 65 breast masses. BI-RADIS grading and lesion elasticity score were determined, and they were compared with pathological results. Results Among 65 lesions, 28 were benign, including 27 with total score of 6 or lower than 6. There were 37 malignant lesions, including 35 with total score higher than 6. The accuracy, sensitivity and specificity of diagnosing by sonoelastography and BI-RADIS was 95% （62/65）, 95% （35/37）and 96% （27/28）, respectively. Conclusion The risk of malignant lesion is increased when the score of ultrasound elasticity score and BI-RADIS grading higher than 6. Sonoelastography combined with BI- RADIS can be used to determine the benign or malignant lesions more objectively, and it is valuable for determining surgery at early stage.
