Molecular breast imaging is a test that uses a radioactive tracer and special camera to find breast cancer. Rather than simply taking a picture of a breast, molecular breast imaging is a type of functional imaging. This means that the pictures it creates show differences in the activity of the tissue.
Molecular breast imaging is a procedure that can help detect breast cancer. You might also hear it referred to as breast specific gamma imaging, scintimammography, or Miraluma. After your doctor injects a radioactive tracer into your vein, a special nuclear medicine scanner will capture images of your breasts.
Objectives Molecular Breast Imaging MBI uses single gamma photons to visualize breast tumors that are often occult on mammography in women with radiographically dense breasts. We designed a low-dose collimator fabricated with tungsten septa and square holes that match the CZT detector pixels. We fuse the images from the two opposed heads to increase SNR and contrast.
Molecular breast imaging MBI is a method for detecting breast cancer. The technique is also known as a Miraluma pronounced mee-ra-LOO-ma test, sestamibi pronounced ses-ta-MI-beescintimammography, or breast specific gamma imaging. This tracer is injected into the body through a vein in the arm.
May As dense breast tissue notification laws expand and draw media coverage, the role of molecular breast imaging MBI also is drawing more attention in breast cancer detection. Physicians and industry experts alike refer to a comparison between the functional imaging capabilities of MBI and the anatomical imaging aspects of other modalities when considering the benefits of pairing supplemental imaging with mammography.

Women with dense breasts must be educated on the available options for secondary screening techniques, including molecular breast imaging MBI. Breast cancer is the second leading cause of cancer deaths among women in developed countries. Typically, women have routine mammograms to screen for breast cancer every one to two years.
What is it? How it works: The short-lived radioactive agent 99mTc-sestamibi accumulates in cancer cells more than normal cells, allowing cancer to be seen on the basis of differences in metabolism. Starting about 5 minutes after intravenous injection of the radiotracer, each breast is gently stabilized between two detectors Figure MBIor between one detector and a compression paddle Figure
Recent developments in the field of breast imaging, however, demonstrate that using a procedure known as molecular breast imaging MBI may be a game changer when it comes to detecting breast cancer in women who have dense breast tissue. MBI uses a unique gamma camera and a radioactive tracer to target cancer in a specific area of the body. Instead of taking a single picture of your breast tissue, MBI technology is known as "functional imaging" because it can show what's going on in the tissue.
A new breast imaging technique pioneered at the Mayo Clinic Cancer Center nearly quadruples detection rates of invasive breast cancers in women with dense breast tissue, according to the results of a major study published in the February issue of the American Journal of Roentgenology. Molecular breast imaging MBI is a supplemental imaging technology designed to find tumors that would otherwise be obscured by surrounding dense breast tissue on a mammogram. Both tumors and dense breast tissue can appear white on a mammogram, making tumors indistinguishable from normal tissue in women with dense breasts.
