MRI relies on a magnetic field, radio waves, a computer, and
software in order to produce images of the body. These images
may then be viewed on the computer or printed out. a “MRI is
a powerful diagnostic tool, especially when used to help detect
breast abnormalities,” says Dr. Biren Shah, a radiologist at St.
Joseph Mercy Oakland. “The image shows great accuracy and
provides more details about abnormalities and therefore, gives us
more information about how to treat the patient.”
Physicians can use MRI to analyze and diagnose certain body
parts or conditions that would not be detected by other imaging
techniques such as ultrasound, x-ray, or CT scanning. Additionally,
physicians prefer MRI for breasts as it enables them to see things
that mammography and ultrasound do not.
ADVANTAGES
Traditional mammography is still recommended, beginning at the
age of 40 for those women with no immediate family history. MRI
is not an alternative to mammography but an ancillary tool that
is used to better image abnormalities or cancers of the breasts.
Additionally, MRI can provide information on stages of cancer,
whereas ultrasound and mammography cannot.
With MRI, physicians can:
• Evaluate abnormalities detected by mammography
• Screen for cancer in women who have implants that may
hinder the accuracy of a normal mammography reading
• Identify breast cancer at the earliest stage possible
• Assess multiple tumor locations
• Assess the effect of chemotherapy
• Better tailor treatment plans to each patient because of
the clarity of picture provided
• Evaluate breast implants. Breast MRI is the best tool
to assess for possible breast implant rupture
Additionally, breast MRI may also utilize contrast material in order
to gain more detailed images. Contrast material helps physicians
determine whether a growth is benign (non-cancerous) or
malignant (cancerous) as well as its exact location. Furthermore,
contract material will also illustrate whether or not lymph nodes
are enlarged.
THE PROCEDURE
MRIs are a non-invasive, virtually pain free procedure. Depending
on the facility, you may be asked to get into a gown or you may be
able to wear your own clothes. Additionally, you may follow your
own dietary routine unless otherwise directed. The radiologist
will ask you about your medical history and provide the contrast
material if necessary.
You will lie in the MRI unit and radio waves will be directed to the
area of your body under study. The computer will then generate
images of the body part. The procedure is usually done on an
outpatient basis and generally takes 30-45 minutes.
