The First Experience in Application of Tomosynthesis in the Diagnosis of NonPalpable Breast Cancer
The relevance of studying the incidence of breast cancer is a problem of modern health care due to a steady growth of morbidity, including those of malignant character. About 1 million new cases of breast cancer are detected yearly in the world, predicting growth in the number of cases by 2014 to 1.45 million. Currently, a certain progress has been made in the diagnosis of early forms of the disease through the introduction of modern technologies of beam diagnostics. The most effective among them is an X-rays examination. However, there is a number of unresolved problems in the differential diagnosis of non-palpable breast formations because of their early symptoms non-specificity. In this regard, new technologies are developed that can enhance these capabilities. Despite the widespread use of mammography, there is still a number of limitations. This is primarily due to the complexity of interpreting the images of mass lesions because of superimposed structural elements of breast tissue located in different planes. Breast tomosynthesis is a new technology that allows avoiding these disadvantages. Using a flat panel X-ray detector and rotating the tube in relation to the image receiver, we perform a series of low-dose exposures at different angles, converting further the received information into a series of tomograms.
