MRI stands for magnetic resonance imaging. It uses magnetism and radio waves to create cross sectional pictures of the body. It produces pictures from angles all around the body and shows up soft tissues very clearly.
Unlike a mammogram, which uses X-rays to create images of the breast, breast MRI uses magnets and radio waves to produce detailed 3-dimensional images of the breast tissue. Before the test, you may need to have a contrast solution dye injected into your arm through an intravenous line. The solution will help any potentially cancerous breast tissue show up more clearly.

However, it is a limited tool when used for screening.
Magnetic resonance imaging MRI of the breast uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of the structures within the breast. It is primarily used as a supplemental tool to breast screening with mammography or ultrasound. It may be used to screen women at high risk for breast cancer, evaluate the extent of cancer following diagnosis, or further evaluate abnormalities seen on mammography.
Breast MRI is used in breast cancer screening for women at higher than average risk. Screening with mammography plus breast MRI is not recommended for women at average risk of breast cancer. Compared to mammography, screening with breast MRI has some drawbacks [ ]:.
What is a breast magnetic resonance imaging MRI?
