Low-dose MBI as effective as mammo in screening dense breasts

November 29, 2012

Low-dose molecular breast imaging (MBI) can outperform screening mammography to detect cancer in women with dense breasts, according to a study presented on Tuesday at the annual RSNA meeting.

Researchers from the Mayo Clinic in Rochester, MN, used an 8-mCi dose of technetium-99m (Tc-99m) sestamibi rather than 20 mCi in MBI exams on more than 1,600 women with dense breasts. MBI still detected more cancers than mammograms, the group found.
