Who should get an MRI of the Breast?
Most patients will have mammography first, followed by ultrasound. If there are any suspicious areas on these studies, or if you have recently been diagnosed with breast cancer, your doctor may then refer you for an MRI of the breast. Some patients will have an MRI of the breast annually (or sooner) if they have a history of breast cancer or a strong family history of breast cancer. Your doctor will decide if breast MRI is necessary. The ACS (American Cancer Society) and the ACR (American College of Radiology) feel that MRI of the breast should be used in conjunction with mammography and ultrasound of the breast. MRI is the best way to detect an implant rupture in women with augmented breasts. If you are still menstruating, it is best to get your MRI 7-10 days after the first day of your menstrual period. If you are taking hormone replacement therapy, the procedure may be performed at any time.

What is involved in MRI of the Breast?
MRI of the breast characterizes breast tissue by how it enhances with contrast. Before we begin scanning, we will start an IV in your hand or arm for a contrast injection of gadolinium. You will be positioned on your stomach, with your breasts hanging freely through an imaging device (a breast coil). You will not feel compression as you would in a mammogram. Once positioned, you will go feet first, on your stomach, into the magnet. The magnet looks like a large tunnel that is open on both ends. You will be positioned to look at the technologist scanning you. You will hear a series of loud banging noises. This means we are taking images. It will be very important to hold still for the entire length of the procedure. This should take 45-60 minutes. You can breathe normally for the entire procedure. You may be asked to have blood work drawn if you have any problems with your kidney function, are 60 or older, diabetic or have high blood pressure.

What are the advantages of Breast MRI?

MRI of the breast will give your doctor a lot of valuable information. MRI screening for high-risk women may enable the detection of otherwise unsuspected breast cancers. If you have just been diagnosed with breast cancer, it will help your doctor decide your treatment plan. When combined with mammography and ultrasound, it may give your doctor a complete idea of your breast health.
