This work analyzed the background breast tissue enhancement in the contralateral normal breast of patients diagnosed with breast cancer. A computer program is used to segment the entire fibroglandular tissue, and a kernel of 3 by 3 pixels is used to search the hot spot. The hotspot enhancement is 2 fold higher compared to the mean background tissue enhancement. A negative correlation with age was found (r=0.35 for hotspot, r=0.33 for mean tissue enhancement). The presented method may be used to evaluate the role of background tissue enhancement as a risk factor in development of contralateral breast cancer.
