Análise comparativa dos métodos de imagem mamografia bidimensional e mamografia tridimensional na investigação de carcinoma mamário: uma revisão integrativa da literatura

Abstract

Introduction In view of the thematic relevance and the promotion of early detection strategies that favor the diagnosis of breast cancer, it is clear the need to highlight the techniques of early detection of mammary carcinoma and of the digital and threedimensional mammography methods. Objective This study aims to compare the efficacy of two-dimensional and three-dimensional digital mammography imaging methods in the investigation of mammary carcinoma. Methodology This is an integrative review of the literature, using a critical analysis of the scientific references compiled to address the descriptors in Health Sciences, Digital Breast Tessosynthesis, Digital Mammography, Mammary Carcinoma and Early Diagnosis and with publication between 2013 and 2017. Result As with most types of cancer, if discovered early and treated correctly, the chances of cure are very good, otherwise, that is, when the cancer is detected late, the damage caused by the disease can be profoundly physically, psychologically and socially. There is broad agreement that mammographic screening reduces breast cancer mortality in asymptomatic women. Mammography is currently considered one of the most reliable techniques for the early detection of breast cancer, consisting of the ideal method for the identification of subclinical lesions. Digital Tomosynthesis promises to address both concerns, allowing for three-dimensional reconstruction of breast tissue, which can then be viewed as sequential sections through the breast, decreasing the overlapping effect on dense tissues. Conclusion Staged diagnosis reduces the chances of cure and raises the mortality rate. Three-dimensional mammography is immensely valuable as a complementary mammography exam, requiring research and investments for its dissemination. And two-dimensional mammography should continue with research in order to minimize the disadvantages and seek the best result in the acquisition of images and characterization of radiological findings.
