在乳腺肿瘤早期应用超声检查诊断是至关重要的。而二维超声是鉴别乳腺癌与乳腺良性肿块最有效、最基本的方法；彩色多普勒则是通过肿瘤部位的血供情况来鉴别肿瘤的恶、良性，均有较高的准确率；超声造影是通过实时显示造影剂，对肿瘤进行观察，并鉴别肿瘤的恶、良性。近几年还有一些超声诊断技术产生并发展起来，如弹性成像技术、实时灰阶超声造影以及能量多普勒技术等，为乳腺肿瘤的早期诊断提供了有利依据。“,”It is crucial to apply ultrasound diagnosis in early stage of breast cancer.The two-dimensional ultrasound is the most effective and basic way to identify the breast cancer and benign breast lumps.Color Doppler is to identify the malignancy and benign nature of the tumor through the blood supply of the tumor location,both of them have high accuracy.Ultrasound imaging is to observe the tumor and identify the malignancy and benign nature of tumor through the real-time display of contrast medium.In recent years,there are some other ultrasonic diagnosis technologies being devel-oped,such as elasticity imaging technology, real-time gray-scale ultrasound imaging and power Doppler technology,which can provide a favorable basis for the early diagnosis of breast cancer.
