Molecular Breast Imaging (MBI)

This procedure, also known as breast-specific gamma imaging (BSGI), is performed as a follow-up study to a mammogram that is inconclusive or detects cancer, or in combination with screening mammography for women with especially dense breasts or women who have a high risk of cancer.

MBI can be used to:

  • Detect small (less than 1 cm) lesions that mammography and physical exams may miss
  • Detect cancers that are difficult to detect using mammography
  • Determine the exact location of a tumor before surgery

During the Procedure:

  • You will receive an injection with a low dose of the MBI radiotracer, which will accumulate in malignant tissue.
  • After several minutes, you will go to the MBI equipment, which looks similar to a mammogram machine.
  • The technologist will take pictures of your breast with a special gamma camera using standard mammogram positions. Each image takes approximately 10 minutes, and the entire procedure will last about 46 to 60 minutes.
