The relationship between a lesion in the breast and its effect on contrast uptake kinetics in the breast parenchyma (PS) is unclear. This study investigated whether the quantitative analysis of MR contrast-enhancement kinetics of BP and lesions improves our ability to discriminate between benign and malignant tumors. We analyzed 102 lesions using a linear principal component analysis (PCA) and found that we can correctly identify benign lesions compared to malignant lesions by quantitatively comparing its enhancement with the adjacent BP. We almost reached statistical significance when performing the same analysis on malignant lesions.
