What is Breast MRI?

Magnetic Resonance Imaging (MRI) of the breast has become an extremely helpful tool in evaluating mammogram abnormalities and identifying early breast cancers, especially in women at high risk.  It has also shown to alter surgical management.

Unlike x-rays and CT scanning, MRI uses no ionizing radiation to produce images. Instead, magnetic fields and radio waves are used to interact naturally with the atoms within your body. The signals received from these interactions are processed by a special computer and converted into finely detailed images.  MR images can help physicians evaluate the function as well as the structure of many organs. 

Procedure: What you can expect During the Breast MRI

Although MRI is an advanced medical technique, the exam itself is relatively easy and comfortable for most people.

The technologist will escort you to a changing room and then to the a consultation room. You will asked a series of screening questions prior the MRI evaluation.  The procedure usually takes between 15 to 30 minutes but sometimes longer depending on the image guidance and the number of sites targeted.

You will be asked to lie on your stomach on a cushioned table with your breasts in an imaging coil.  Once you are comfortable positioned, the table will move into the magnet. From the control area, the technologist will stay in constant contact with you, both visually and through an intercom.

As the exam begins you will hear a variety of muffled thumping or clicking sounds. These sounds are normal during the exam and should not be cause for concern. Other than the muted sounds you will hear, MRI produces no bodily sensations.

Afterwards

Your exam will be carefully reviewed by a radiologist, a physician specially trained to interpret MR imaging of the breast. He will provide your doctor with a detailed report. Your doctor will discuss these results with you and explain what they mean in relation to your health.
