  • BSGI (Breast Specific Gamma Imaging)

    Northern Arizona Radiology is pleased to offer BSGI, a new imaging technique that can aid in diagnosis when a mammogram is inconclusive.

BSGI

These studies can reveal important information that can help your doctor more accurately determine if an area of concern is cancerous or not. BSGI is best used as a valuable “next step” following a mammogram that reveals an area of concern. A mammogram is an x-ray study of the breast used to image tissue structure and density. If you are scheduled for additional testing, your mammogram may have been difficult to interpret due to some specific characteristics of your breast tissue. For example, dense breast tissue is displayed on a normal mammogram as thick white areas. Abnormalities in breast tissue display as white or light areas. Because the two often display as the same density and structure, it may be difficult to locate masses. BSGI, working on a cellular or metabolic level, provides the needed capability of helping differentiate cancer from other structures or benign tissue in the breast.

BSGI is a strong diagnostic tool especially for patients who have:

  • Dense breast tissue
  • Suspicious areas on a mammogram
  • Lumps that can be felt but not seen with mammography or ultrasound
  • Implants and breast augmentation
  • Scarring from previous surgeries

How Does It Work?

BSGI utilizes a specially developed camera that allows for imaging with no compression of the breast. A small amount of tracing agent is injected into the arm or foot, which is absorbed by all of the cells of the body. Because cancerous cells have a higher rate of metabolic activity, the tracing agent usually concentrates in these cells (if present) to a much greater degree than in normal cells. The tracing agent emits invisible rays, and the imaging system is used to examine the breast.
