Breast specific gamma imaging (BSGI)

Breast specific gamma imaging (BSGI) is a safe, comfortable imaging option that can aid in breast cancer diagnosis when a mammogram is inconclusive. Typically used as a less invasive "next step" when a mammogram reveals an area of concern or is inconclusive, BSGI is especially useful in early breast cancer detection and may help prevent the need for a breast biopsy.

BSGI is especially helpful for patients who have:
  • Dense breast tissue
  • Suspicious areas found on a mammogram
  • Lumps that can be felt but not seen with mammography or ultrasound
  • Breast augmentation that may interfere with a mammogram's reading
  • Scarring from previous surgeries

How BSGI works

BSGI uses a special camera that allows imaging with minimal breast compression and a small amount of a tracing agent that's injected into your arm or foot. The tracing agent is absorbed by all the body's cells, but because cancerous cells have a higher rate of metabolic activity, the tracing agent generally concentrates in cancer cells if they are present, showing up as darker areas of enhancement.

During the BSGI treatment, you'll be seated comfortably and each view takes an average of 5 to 10 minutes.
