As we all know, ultrasonography has been commonly used in the examination of various organs in modern medicine, and with the advantages of low cost, non-invasive and non-radiation, it has become one of the important examination items in physical examination. In recent years, the incidence rate of breast diseases has been increasing year by year, and breast tumors have become the first killer threatening women’s health all over the world. In 2005, the Ministry of Health issued a call for a “Breast Disease Census for One Million Women”. Breast cancer is characterized by early asymptomatic, early metastasis and poor prognosis. As an important organ reflecting women’s beauty, the excision or not of the lump is a painful choice for women. Therefore, the detection of early tiny lesions has also become the direction of the ultrasound community’s unremitting efforts, so that accurate diagnosis before surgery is very important. However, conventional breast ultrasonography has difficulty in identifying benign and malignant masses, and the introduction of ultrasonography has become a new milestone in the development of ultrasound medicine. Ultrasonography can be used to examine masses in substantial organs of the human body (e.g. liver, kidneys, breast, lymph nodes). The Fourth Hospital of Harbin Medical University has introduced the color ultrasound diagnostic instrument with the most advanced imaging function in the world, which is the preferred method to identify benign and malignant tumors of parenchymatous organs through intravenous injection of imported DD acoustic contrast agent with tiny bubbles that are harmless to human body, and is relieving more and more patients from their illnesses and pains. The outstanding advantages of ultrasonography and other imaging examinations are real-time dynamics, repeated examinations, good sensitivity, especially the discovery of small early lesions that are not easy to detect by conventional examinations, thus improving the detection rate of malignant tumors by ultrasonography, the contrast agent is non-radioactive, free of allergic reactions and non-toxic side effects, applicable to patients of any age, and the advantages of low examination costs, which has become a reliable examination method for the identification of benign or malignant tumors of various organs with tiny lesions. It has now become a reliable examination method for identifying benign and malignant micro lesions of various organs.
