Breast MRI
What about breast implants and MRI?
What is breast MRI?
Magnetic Resonance Imaging, or MRI, is an advanced, state
of-the-art medical imaging method. MRI uses a powerful but harmless
magnetic field and radiowaves to produce
detailed images of specific
body structures and organs.
MRI scans pose minimal risks to
most patients if safety guidelines
are followed.
How long does it take?
The average Breast MRI exam
takes about 30 to 45 minutes.
How should I prepare?
There
is no pre-exam preparation—you
may eat and drink as you normally
would and take medications as you
normally would.
What should I wear to my appointment?
Please dress comfortably— sweatpants and sneakers are perfect! It is important to not wear clothes with metal zippers, buttons or snaps; no metal is allowed in the MRI exam room. Safety pins, straight pins, metal hair pins and all jewelry must be removed before
entering the room. If you have a ring (such as a wedding band) or other jewelry that cannot be removed, we will test it for magnetic attraction before you may enter the
room.
What can I expect during
the exam?
Breast MRI is a relatively comfortable and
easy exam. You will be asked to lie on
your stomach on a cushioned bed. Your
breasts will be positioned within a padded
cutout on the bed. The bed will move
into the magnet for the exam and you
will hear a muffled humping sound that
will last for several minutes. The most
important thing you can do to make sure
your exam is successful is to hold as still
as you can throughout the procedure. Most breast MRI exams require an injection
of a contrast agent called gadolinium.
An intravenous catheter (I.V.) for
this injection will be placed in your arm
before you lie on the bed. Please tell us if
you have ever had an allergic reaction to
MRI contrast in the past.
What about implants and MRI?
Breast MRI is sometimes used to image
silicone breast implants. If you have
breast implants, it is important that you
tell the technologist when she calls you
prior to your exam. We will also need to
know if your implants are filled with saline,
silicone or oil, or a combination of
these. In addition, we need to know if the
implant has a polyvinyl chloride sponge
covering. Please get this information from
your plastic surgeon’s office prior to your
MRI exam.
