A Comparative Analysis Between Tomosynthesis and Conventional X-ray Modalities in Mammography

According to the World Health Organization, breast cancer is the most prevalent cancer in the world. This metaanalysis has the purpose of answering what the advantages and disadvantages of Projectional Mammography (PM), Digital Breast Tomosynthesis (DBT) and Breast Computed Tomography (BCT). The conclusion of the project is that DBT and BCT, by means of their three dimensional reconstructions, can solve the problem with tissue superposition that PM. This increases the posibilities of finding cancer, and is done without a significant increase in absorbed dose. However, BCT has critical problems such as invisible microcalcifications in the breast, as well as the bad visibility of the axillary lymph nodes.
