Molecular Breast Imaging: What You Need To Know
Molecular Breast Imaging: Overview and Functioning
Molecular breast imaging (MBI) is a test that utilizes a radioactive tracer and a special camera to detect breast cancer. Unlike regular mammography, MBI serves as an additional tool for women with dense breast tissue.
The process involves the administration of a radioactive tracer. This substance tends to accumulate in abnormal areas of cells, such as those found in cancers. During the procedure, the patient lies on their stomach on the MBI table, which has openings for each breast to dangle freely. Two gamma cameras positioned close to the breasts then capture images.
- These cameras generate pictures that highlight areas where the tracer accumulates, indicating potential cancer spots.
- Images are captured from several angles, including front and side views, to allow for a comprehensive examination of any abnormalities.
MBI is typically utilized when other tests do not yield definitive results or in individuals who are considered at high risk for breast cancer due to family history or genetic factors.
Uses and Risks of Molecular Breast Imaging
Molecular breast imaging (MBI) is a diagnostic test that utilizes small amounts of radioactive tracer to identify cancer cells, providing an alternative detection method when mammograms yield unclear results. It is particularly beneficial for individuals with dense breast tissue, where traditional mammograms may struggle to identify tumors accurately. MBI has demonstrated efficacy in detecting cancers within dense breasts and assessing the spread of cancer from its original site.
The procedure involves certain risks, including:
- Exposure to radiation from the tracer material. Although the radiation dose is generally low and considered safe, it is a factor to consider.
- While rare, allergic reactions to the tracer material can occur.
- Discomfort may also be experienced due to the compression of the breasts during the scanning process.
Molecular Breast Imaging offers a supplementary approach for breast cancer detection, providing valuable insights in cases where dense breast tissue poses diagnostic challenges, with the associated risks being relatively low and manageable.

Preparation and Expectations for Molecular Breast Exam
Preparing for a molecular breast exam (MBE) involves simple steps. It is not necessary to fast or take any special medications prior to the exam. The only preparation involves not applying deodorants, lotions, or powders on the breasts and underarms on the day of the test.
-
The MBE process includes the injection of a radioactive tracer into the bloodstream. This tracer binds with certain cells in the body, allowing for clearer visibility during imaging scans. Gamma cameras are used to capture images while the patient lies flat on an examination table.
-
The duration of the procedure is typically between 15-45 minutes, depending on specific elements such as injection time and waiting periods for improved visibility of results.
Concerns about radiation exposure due to the radioactive tracer used in this procedure are common. However, the level of radiation is minimal and considered safe, similar to the radiation levels of an X-ray exam. There may be slight discomfort from the needle prick during injection, but this discomfort usually subsides quickly.
After the procedure is completed, patients can typically return home immediately. There are no dietary or activity restrictions post-procedure since no sedatives are used.
It is important to recognize that every medical procedure carries some level of risk.
Understanding Test Results and Next Steps
Participating in a clinical trial is followed by the step of understanding test results. These results provide insight into an individual's health status and response to the treatment under investigation. It is important to note that test results often require interpretation by medical professionals.
Doctors will discuss test outcomes, potentially using terms like "baseline", which refers to initial measurements at the start of the trial, and "endpoint", marking significant events or changes during or after treatment. Discussions might also touch on "statistical significance," which indicates whether observed changes can be attributed to chance or are likely a result of the intervention.
Upon understanding these findings, the next steps might involve:
- Further testing if positive effects were noted from the investigational treatment.
- Alternatively, if no benefits were observed or if side effects were severe, exploring alternative treatments might be considered.
The process includes a period of review and consideration of the test outcomes and their implications.
Insurance and Molecular Breast Imaging
Molecular Breast Imaging (MBI) is a specialized imaging test useful in detecting breast cancer, particularly in individuals with dense breasts. Coverage for MBI varies among health insurance providers, with some including it as part of preventive care or diagnostic testing, while others may not. It is important to verify the specifics of insurance coverage directly with the provider.
The cost of MBI can be significant without insurance support. This imaging technique utilizes a radioactive tracer and gamma camera to identify cancerous cells, leading to higher costs compared to standard mammography tests. However, insurance coverage can substantially reduce these costs, either fully or partially.
Understanding the potential for out-of-pocket expenses is necessary, as these may occur depending on the deductible and co-pay requirements set by the insurer. Confirming coverage details before undergoing Molecular Breast Imaging is crucial.
