Breast-specific gamma imaging shows better sensitivity than other methods By Rebekah Moan Breast-specific gamma imaging demonstrates better specificity and sensitivity than mammography, ultrasound, and MRI, according to several studies presented at the RSNA meeting.

BSGI also detected an additional suspicious occult lesion in 29% of women.
