Molecular Breast Imaging (other)
Molecular breast imaging can refer to: * Scintimammography (detects gamma rays often from a technetium 99 compound) * Positron emission mammography Positron emission mammography (PEM) is a nuclear medicine imaging modality used to detect or characterise breast cancer. Mammography typically refers to x-ray imaging of the breast, while PEM uses an injected positron emitting isotope and a dedica ...

Scintimammography
Scintimammography is a type of breast imaging test that is used to detect cancer cells in the breasts of some women who have had abnormal mammograms, or for those who have dense breast tissue, post-operative scar tissue or breast implants. Scintimammography is not used for screening or in place of a mammogram. Rather, it is used when the detection of breast abnormalities is not possible or not reliable on the basis of mammography and ultrasound. Procedure In the scintimammography procedure, a woman receives an injection of a small amount of a radioactive substance which is taken up by cancer cells, and a gamma camera is used to take pictures of the breasts. Technetium-99m sestamibi (99mTc-MIBI) is the most commonly used radiopharmaceutical. When performed with MIBI the procedure may also be known as a Miraluma test. The typical dose is 740–1,110 megabecquerels (MBq) with the patient lying prone on the bed for imaging approximately 10 minutes after injection. 99mTc-DMSA and ...
