【摘要】目的评价超声弹性成像在乳腺良恶性肿块鉴别诊断中的应用，总结诊断经验。方法以2014年1月～2015年6月医院收治的109例乳腺肿块患者作为研究对象，以病理诊断为“金标准”，对比常规超声、CDFI、实时弹性成像、3种方法联合诊断效用。结果 3种方法联合应用敏感度、特异度、符合率、阳性预测值、阴性预测值高于其它3种方法；实时弹性超声敏感度、特异度、符合率高于常规超声与CDFI，差异具有统计学意义（P＜0．05）。结论超声弹性成像可提高乳腺良恶性肿块鉴别诊断中效用，弹性应变率比值法、VTQ法各有优劣。【关键词】超声弹性成像；乳腺癌；定性诊断

Objective To evaluate the application of ultrasonic elasticity imaging in the diagnosis of benign and malignant breast masses and sum up the experiences of the diagnosis． Methods 109 cases with breast lumps，which admitted in our hospital during from January 2014 to June 2015，were selected as the research object． Diagnostic utility of conventional ultrasound，CDFI，real-time elastography and joint three methods were compared in pathological diagnosis for"gold standard"． Results Three methods combined use of sensitivity，specific degrees，coincidence rate，positive predictive value，negative predictive value were higher than other three methods，real-time elastography sensitivity，specific，coincidence rate higher than that of conventional ultrasonography and of a CDFI，statistically significant difference（P＜0．05）． Conclusion Ultrasonic elastography can improve the utility in the differential diagnosis for benign and malignant breast，elastic strain rate ratio method，VTQ method have their advantages and disadvantages．

随着社会经济的发展，我国乳腺癌发病率呈快速上升趋势，已成为女性最常见的恶性肿瘤。晚期乳腺癌2年内死亡率高达50%，早期检出、诊断对于提高治疗效果、改善乳腺癌患者预后具有重要意义［1］。乳腺癌筛查诊断方法较多，超声检查是乳腺疾病诊断、随访不可或缺的方法，操作简单、廉价、重复性好，在鉴别乳腺囊实性病变、致密型乳腺疾病诊断中具有较高的应用价值［2］。本次研究试以2014年1月～2015年6月医院收治的109例乳腺肿块患者作为研究对象，评价超声弹性成像在乳腺良恶性肿块鉴别诊断中的应用，总结诊断经验。
