Currently, breast cancer has become the most common malignant tumor in women worldwide. With the incidence of breast cancer increasing year by year and the younger age of onset, how to effectively detect and diagnose it at an early stage has become a concern for women. Under the current medical level, various imaging methods are mainly used to diagnose breast cancer. As we all know, mammography is the main imaging method to diagnose breast cancer, which is characterized by microcalcifications on X-ray, but for Asian women with dense breast tissue and some non-calcified breast cancers, the sensitivity of mammography is greatly reduced. In contrast, magnetic resonance imaging (MRI) has a higher resolution for soft breast tissue and is not affected by the denseness of the breast gland, but it is expensive and requires intravenous contrast, to which many people are allergic, which also affects its application prospects. Therefore, ultrasonography is more widely used in breast examination to detect breast masses and check the status of axillary lymph nodes, but it is not sensitive to microcalcifications or microscopic tumors, and is subjective due to the operator’s technique and experience. In November 2010, our hospital was the first in the province to develop the application of automated breast volume scanner (ABVS). ABVS is a three-dimensional ultrasound imaging technology developed by Siemens in Germany for breast examination, which is particularly suitable for dense breast tissue and patients with a family history of breast disease because it has a special high-frequency automatic probe that can acquire a full-volume image of the breast and can obtain cross-sectional, longitudinal and coronal image information. It is particularly suitable for patients with dense breast tissue and a family history of breast disease, and can effectively improve diagnostic accuracy. Compared with conventional ultrasound, ABVS has the advantage of being operator-independent, eliminating operator-induced differences in diagnostic level and overcoming the disadvantages of poor repeatability of conventional ultrasound; its unique coronal plane also provides a new perspective and high sensitivity for small tumors and microcalcifications. At the same time, ABVS can obtain continuous tomographic images with a layer thickness of 0.5 mm, which provides a more easily understood full picture of breast anatomy and structural features, especially the lobules and surrounding tissues near the breast ducts can be well displayed, and its MRI-like volumetric coronal views and mammogram-like inverse images are well received by clinicians. The system also provides some new diagnostic techniques for functional breast imaging, including elastography, which is a qualitative diagnostic imaging technique that further determines potential pathological changes by showing the relative hardness of the tissue, and adipose tissue correction imaging, which optimizes the real-time display of adipose tissue by enhancing lateral and contrast resolution. With the adoption of the above technologies, physicians can obtain more detailed information about the tissue than before. Moreover, the system preserves complete diagnostic information and helps standardize ultrasound examinations of the breast. This new technology has been carried out for more than three years and has a wide range of clinical applications. We have completed more than 8,000 examinations in total, and 30% of these patients have obtained surgical pathology results, which is the highest in the country. It is believed that the increasing promotion of this technology will turn a new page for the difficult problem of early detection of breast cancer.
