Background uptake of breast-specific gamma imaging: correlation with mammographic breast density and background enhancement of breast MRI.
OBJECTIVE
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).


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).


CONCLUSIONS
Interpreting BSGI of women showing high mammographic breast density or background enhancement of breast MRI needs to be carried out with caution.
