Breast Specific Gamma Imaging

Breast Specific Gamma Imaging (BSGI), also known as Scintimammograpny, is used as a follow-up exam to evaluate abnormalities of the breast, which have been found during a mammography screening. It is a noninvasive procedure that involves the injection of a radiotracer. This drug accumulates in the breast and emits radioactivity, which is measured by a gamma camera to gather the results of the exam.

BSGI is Provided at the Following Location:

  • Riverside Regional Medical Center
  • Riverside Diagnostic and Breast Imaging Center – Oyster Point

How should I prepare for a BSGI Exam?

• You will be asked to wear a gown during the procedure.
• Please let us know if you are breastfeeding, pregnant, or taking any medications, including
vitamins and herbal supplements, and if you have any known food or drug allergies, had recent illnesses or other medical conditions.

What should I expect during the exam?

BSGI is usually an outpatient procedure. The exam lasts 45-60 minutes. One breast at a time is placed next to a camera, and compressed. At least two images of each breast are obtained.

What will I experience during the procedure?

When the radiotracer is injected, you may feel a slight prick. It is normal to have a metallic taste afterwards. The exam itself causes no pain, but you may feel discomfort from remaining still for periods of time.
