Purpose: To investigate the relationship between background uptake of breast-specific gamma imaging (BSGI) mammographic breast density and background enhancement of breast magnetic resonance imaging (MRI).
Materials and methods: The level and texture of background uptake of BSGI, mammographic breast density, and background enhancement of breast MRI are retrospectively reviewed in 104 patients.
Results: Heterogeneous and increased background uptake of BSGI was significantly correlated with high mammographic breast density (P=.016, P=.001) and increased background enhancement of breast MRI (P=.015, P=.017).
Conclusion: Interpreting BSGI of women showing high mammographic breast density or background enhancement of breast MRI needs to be carried out with caution.
