In this study we investigated the density distribution
in the four quadrants of the breast and compare between
a Western and an Asian cohort. Breast MRI from 250
Western women and 156 Asian women was semi-automatically
segmented for the quantification of quadrant breast
density. In total 91 right breasts and 65 left breasts
from Asian cohort, and 144 right breasts and 106 left
breasts from Western cohort were analyzed. Our study
noted that Asian women have the most common highest
density in the inner upper quadrant and Western women
have the most common highest density in the outer lower
quadrant.
