WHAT’S THIS PROCEDURE?

Scintimammography

Scintimammography, a form of breast imaging, is an examination used to investigate a breast abnormality that’s been found in a mammography, where more detail is needed.

The procedure is non-invasive and involves the injection of a radiotracer, or drug that emits radioactivity, into the patient.

After injection, the radiotracer eventually accumulates in the breast, where it gives off energy in the form of gamma rays. This energy is detected by a device called a gamma camera. The camera works with a computer to measure the amount of radiotracer absorbed by the body and to produce finely detailed pictures showing both the structure and function of organs and tissues.

Because the radiotracer accumulates differently in different kinds of tissue, it can help doctors determine whether cancer could be present, and decide whether a biopsy or additional follow-up is necessary.
