Molecular Breast Imaging (MBI), also known as Breast-Specific Gamma Imaging (BSGI), is a procedure that is able to detect breast cancers missed by mammography and ultrasound, particularly in women with dense breasts. The MBI procedure is now available in hundreds of breast centers nationwide and is commonly utilized as a tool along with mammography and ultrasound to help in the diagnosis of breast cancer. Although the radiation dose associated with this procedure is already low enough to be used in select cases, new research is being conducted to find ways to reduce the dose further so that MBI may be used in annual breast cancer screening for high-risk women with dense breast tissue. The latest results from this research were presented at the Chicago International Breast Course in October by Marcela Bohm-Velez, M.D., the principal investigator of an ongoing trial at Weinstein Imaging Associates in Pittsburgh, Pa.
