RMN Mamar uses magnetic waves to produce detailed, 3-dimensional images of the breast tissue. It can detect and assess cancers and other abnormalities of the breast, and it can also show how these changes may be affecting the surrounding tissue. In contrast to mammography and ultrasound, MRI does not use radiation (X-rays).
The test is done in a hospital or outpatient clinic. A radiologist or radiology technologist will perform the exam. You will be asked to sign a consent form. This is to confirm that you understand the benefits and risks of the MRI and agree to have it done.
You will lie on a padded table that has openings specifically designed for the breast area. The table slides into the opening of the MRI machine, which looks like a large donut with a tunnel-like space. The machine makes loud tapping and thumping sounds while it takes the pictures. Some people find these noises disturbing, and they can be distracting. Your health care team can give you earplugs or headphones to wear to reduce the noise.
Precision in Imaging: How Breast MRI Enhances Breast Cancer Detection
A contrast solution may be injected into a vein in your arm before the MRI to highlight blood flow and make some tissues, such as cancerous ones, appear more clearly. The contrast solution will affect your kidneys, so your doctor will run tests to check how well your kidneys are working.
You should let your healthcare team know if you are breastfeeding or plan to do so at the time of the scan. Breastfeeding can change the appearance of certain tissues on MRI, and it can interfere with the clarity of some MRI scans.
