Background parenchymal uptake on molecular breast imaging as a breast cancer risk factor: a case-control study

摘要

BackgroundMolecular breast imaging (MBI) is a functional test used for supplemental screening of women with mammographically dense breasts. Additionally, MBI depicts variable levels of background parenchymal uptake (BPU) within nonmalignant, dense fibroglandular tissue. We investigated whether BPU is a risk factor for breast cancer.
