Molecular Breast Imaging (MBI) is a breast imaging test that use a small amount of radioactive material. This test can find cancers hidden within dense breast tissue on a mammogram, but is not usually recommended for breast cancer screening because the radiation from MBI is to the whole body. This is not like a mammogram, where only the breasts receive radiation (in a very small amount), and not like an Ultrasound or MRI, where there is no ionizing radiation at all.
MBI is not used in women who are pregnant.
