Detecção da assimetria mamária

Abstract

This article presents the software "DENSIRADS" that organizes mammography image database in accordance with the classified breast density composition described in the BI-RADS (Breast Imaging Reporting and System Date). The methodology used in the "DENSIRADS" allows indicating the lack of symmetry in the mammography density. Nowadays researchers of the area agree that the lack of symmetry between the densities would be an important factor in diagnosis of the breast cancer. The image database used was the MIAS (Mammographic Image Analysis Society), classified by radiologist and available on-line. Sixty images had been used, being 15 pairs (30 images) classified with asymmetry and 15 pairs (30 images) classified as normal. From that 15 pairs of asymmetry images, 9 were cancer cases. The sensitivity of the DENSIRADS for the MIAS database to asymmetry images was of the 78 % and specificity of the 75%. © Springer-Verlag Berlin Heidelberg 2007.
