文摘

The purpose was to evaluate the relationship between body mass index (BMI), mammographic breast density, magnetic resonance (MR) background parenchymal enhancement (BPE), and MR fibroglandular tissue (FGT) in women with breast cancer.

Methods

Our institutional database was queried for patients with preoperative mammography and breast MR imaging.

Results

There were 573 women eligible for analysis. Elevated BMI was associated with advanced stage of disease (P=.01), lower mammographic density (P<.0001), lower FGT (P<.0001), higher BPE (P=.005), and nonpalpable lesions (P=.04).

Conclusions

Higher BMI was associated with decreased breast density and FGT. Higher BMI was also associated with advanced stage disease and nonpalpable tumors on clinical exam.
