BSGI results showed an additional suspicious lesion missed by mammography and physical exam in 46 (29 percent) of the women. In 14 (36 percent) of the 39 women who underwent biopsy, the newly discovered lesions were cancerous.
"The data suggest that BSGI allows for the diagnosis of more and earlier breast cancers," Dr. Brem said.
Dr. Brem pointed out that BSGI is not meant to replace mammography, but to be used as an adjunct to mammography. "It is an excellent tool for locating difficult-to-detect cancers and for screening high-risk women who have normal mammograms and physical examination," she said.
AT A GLANCE -- Breast-specific gamma imaging (BSGI) is an effective method of detecting hard-to-find breast cancer. -- BSGI identifies cancers not visible on mammograms and not found by clinical examination. -- BSGI findings are based on the metabolic activity of cancer cells.
Disclosure: Dr. Brem is on the board of directors of iCAD, Inc., a board member of Dilon Technologies LLC and a consultant for Orbotech Ltd.
