Breast MRI (magnetic resonance imaging) is a diagnostic imaging test that uses a powerful magnet and radio waves to produce detailed images of the breast tissue. It is typically used as a supplemental screening tool for women at high risk of developing breast cancer or for women with suspicious findings on mammography or ultrasound.
During the procedure, the patient lies on a table and is moved into a cylindrical MRI machine. The machine creates a magnetic field that aligns the protons in the body's cells. Radio waves are then used to temporarily disturb the alignment of these protons, which emit a signal that is detected by the machine and used to create detailed images of the breast tissue.
Breast MRI is generally considered safe, but there are some risks associated with the procedure. Patients with certain medical conditions, such as kidney disease or claustrophobia, may not be good candidates for MRI. In addition, there is a small risk of an allergic reaction to the contrast dye used in some breast MRI procedures.
Overall, breast MRI can be a valuable tool in the early detection and diagnosis of breast cancer. However, it should not be used as a substitute for mammography or other screening methods, and should always be performed in conjunction with a thorough clinical evaluation by a qualified healthcare provider.
