Clinical Application Progress of Dynamic Contrast-Enhanced MRI in Breast Background Parenchymal Enhancement
Breast cancer has a high incidence rate among female malignant tumors,and the this rate is showing an increasing trend year by year.Background parenchymal enhancement(BPE)in breast dynamic contrast-enhanced MRI can be used as an image biomarker for promoting the targeted,precise diagnosis and treatment of breast lesions for sustainable development.BPE refers to the enhancement of normal fibroglandular breast tissue,influenced by various factors including breast blood supply,endogenous and exogenous hormones.This paper reviewed the classification and quantitative measurement of BPE,factors influencing BPE,the correlation between BPE and the risk of breast cancer,as well as the relationship between BPE,neoadjuvant chemotherapy for breast cancer,and prognosis.
