摘要
目的 探讨超声弹性成像对乳腺良恶性结节的诊断价值。方法 选取2011年6月~2015年6月来我院就诊的115例乳腺良恶性肿瘤患者,病理诊断结果显示共有170个病灶,其中良性结节108个,恶性结节62个,采用超声弹性成像技术诊断乳腺结节的良恶性,并与病理诊断结果作比较;采用改良的超声弹性成像5分法判断乳腺结节良恶性的准确性。结果 超声弹性成像诊断恶性结节的灵敏度为80.6%,特异度为83.3%,正确指数为0.639,阴性预测值为88.2%;阳性预测值为73.5%。超声弹性成像评分≥4分时,恶性结节比率（80.6%）明显高于良性结节（16.7%）（P〈0.05）。结论 超声弹性成像对乳腺良恶性结节的诊断价值较高,可较准确地准确鉴别乳腺结节的良恶性,值得各大医院广泛推广应用。
Objective To discuss the diagnostic value of ultrasound elastography for benign and malignant nodule of breast. Methods 115 cases with benign and malignant tumor of breast treated by our hospital from June 2011 to June 2015 were selected. Pathological diagnosis showed that there were a total of 170 lesions,there were 108 benign nodules, 62 malignant nodules,and ultrasound elasticity imaging technique was used to diagnosed the benign and malignant nod- ule of breast,and its result was compared with pathological diagnosis result;J-point method of modified ultrasound elas- ticity imaging was used to judge accuracy of benign and malignant nodule of breast. Results The sensitivity of ultra- sound elastography in the diagnosis of malignant nodule was 80.6%,the specificity was 83.3%,the correct index was 0.639,the negative predictive value was 88.2%,and the positive predictive value was 73.5%.When ultrasound elastogra- phy score ≥4 points,the ratio of malignant nodule （80.6%） was significantly higher than that of benign nodule （16.7%） （P〈0.05）. Conclusion Diagnostic value of ultrasound elasticity imaging in the diagnosis of benign and malignant nodule of breast is higher,it can accurately identify the benign and malignant nodule of breast,and it is worthy of wide popular- ization and application in major hospital.
