Scintimammography

What Scintimammography Means in Everyday Medical Language

Scintimammography is a special type of breast imaging test that helps doctors find cancer cells in the breast. It is also called the Miraluma Test or Sestamibi Breast Imaging. Unlike a mammogram, which uses X-rays, this test uses a small injection of a radioactive substance called technetium 99. Cancer cells tend to absorb this substance more than normal breast tissue. After the injection, a special camera called a gamma camera takes pictures of the breasts to show areas where cancer cells might be present.

Why Scintimammography Can Matter in Cancer Care

This test is especially helpful for women who have had abnormal or unclear mammogram results. It is often used when breast tissue is dense, when there is scar tissue from surgery, or when breast implants make mammograms harder to read. Dense breast tissue can make it difficult for mammograms to detect cancer clearly. Scintimammography can sometimes find cancers that mammograms miss. However, it is not used for routine breast cancer screening because it involves exposure to radiation and may not detect all types of breast changes.

What Patients Might Experience or See When This Term Comes Up

If your care team recommends scintimammography, you will receive an injection of a small amount of radioactive material, usually in the arm opposite the breast being tested. The injection is generally safe, but it does expose you to more radiation than a standard mammogram. After waiting a few minutes, you will lie still while the gamma camera takes pictures of your breasts. The test usually takes longer than a mammogram. You might see the test called by different names, such as Miraluma Test or Sestamibi Breast Imaging, in your medical records or reports.

What Scintimammography Does Not Automatically Mean

It is important to understand that not all areas that absorb the radioactive substance are cancer. Some benign (non-cancerous) conditions, like fibroadenomas, can also show up on the test. A positive result does not automatically mean cancer, and a negative result does not guarantee there is no cancer. Doctors use this test carefully and usually alongside other exams and tests to get a clearer picture.

Common Sources of Confusion and Questions to Ask Your Care Team

The test is known by several names, which can be confusing. If you see terms like scintimammography, Miraluma Test, or Sestamibi Breast Imaging, they refer to the same procedure. If this test is mentioned in your medical records or during your care, ask your doctor or nurse how it applies to your situation. You might ask why this test is recommended, how it differs from a mammogram, what the risks are, and what the results might mean for your care plan.

How to Read the Term in Context and Next Steps

Seeing the term scintimammography or Miraluma Test in a report or discussion does not mean you have cancer or that a certain treatment is planned. It is one piece of information that helps doctors understand breast health better. This explanation is for education and cannot decide what is right for you. The best next step is to ask your care team what this test means for your specific situation and how it fits into your overall care plan.
