Does breast cancer screening with magnetic resonance imaging MRI , alone or with mammography, improve diagnostic yield? Screening with MRI is not for everyone. Women who undergo breast cancer screening with MRI are much more likely to be referred for biopsy— that will ultimately be negative—than if they have screening mammography alone. This is even true of women with a personal history of breast cancer. The benefit of possible early detection of breast cancer with MRI has to be carefully weighed against unnecessary additional diagnostic maneuvers.

A study suggests that breast cancer screening with MRI twice per year is better than one mammogram per year for finding breast cancer early in young women with a high risk of breast cancer. The research was published online on Aug. Between and , the study enrolled women at high risk for breast cancer, including women with a known genetic mutation linked to breast cancer:. All the women had a breast exam done by a doctor and an MRI every 6 months, as well as a digital mammogram every 12 months, for the length of the study.

Magnetic resonance imaging MRI of the breast is primarily used as a supplemental tool to breast screening with mammography or ultrasound. A breast MRI is mainly used for women who have been diagnosed with breast cancer, to help measure the size of the cancer, look for other tumors in the breast, and to check for tumors in the opposite breast. For certain women at high risk for breast cancer, a screening MRI is recommended along with a yearly mammogram. Thus, although breast MRI is useful for women at high risk, it is rarely recommended as a screening test for women at average risk of breast cancer. Also, breast MRI does not show calcium deposits, known as micro-calcifications which can be a sign of breast cancer.
What is a breast magnetic resonance imaging MRI? Magnetic resonance imaging MRI is a diagnostic exam that uses a combination of a large magnet, radio waves and a computer to produce detailed images of organs and structures within the body. The MRI machine is a large, cylindrical tube-shaped machine that creates a strong magnetic field around the patient. The magnetic field, along with radio waves, alters the hydrogen atoms' natural alignment in the body.
