Breast MRI uses magnetic fields and radio waves to create detailed, computer-generated images of the breast tissue. The images can reveal tumors, cysts, or other abnormalities. It is important to note that MRI does not use radiation, unlike mammography or ultrasound.
What does an MRI of the breast show?
MRI is an extremely useful test for detecting and staging cancer, particularly in dense breast tissue where cancer cells are more difficult to detect. MRI can also determine whether a tumor is confined to one part of the breast (e.g., invasive lobular cancer) or is diffuse and spread throughout the breast. RMN Mamar information is very important for treatment planning.
A radiologist or radiology technologist will perform the exam. You will lie on a padded table with your breasts resting in plastic, cup-shaped devices that are not compressed as they are during a mammogram. Because movement can affect the quality of the images, you must remain very still during the test. You may hear tapping or thumping noises from the machine during the imaging sequence. Earplugs will be provided if necessary. The radiologist can communicate with you through an intercom at any time, and some centers offer headphones for music to make the procedure more comfortable.
A member of your health care team will give you a contrast dye, called gadolinium, that helps the radiologist better see certain areas of interest in your breast. The contrast dye may cause allergic reactions in some patients. If you have any allergies, tell the member of your health care team.
