From: Mammographic texture and risk of breast cancer by tumor type and estrogen receptor status
Representative images with similar densities but different groups: FD_TH_75 values in the top and bottom 20% of values matched by BMI, PD, age, case status, and study. The top row has similar low PD densities (17%) while the bottom row has a relatively high PD (67%). The inner black delineation lines in each breast image show the delineation lines of the tissue used to describe FD_TH_75. The outer black delineation lines show the delineation lines of the tissue used to describe FD_TH_15. The top left and bottom left images show a top 20th percent tile value of FD_TH_75 while the top right and bottom right images show a bottom 20th percent tile value
