About Abdominal MRIMagnetic Resonance Imaging (MRI)
scans can be used to give your physician precise information about the
organs within your abdomen and pelvic area. Because images produced by MRI
are very detailed, this technology can detect small changes or
abnormalities. Abdominal MRI exams are commonly prescribed to evaluate
unexplained pain, abnormal blood tests, history of cancer or lumps and
masses that can be felt.
What to expectYou
will lie comfortably on a table that moves within a large magnet. You will
be able to communicate with the technologist through a two-way intercom.
During
the scan, as with all MRI exams, you will hear various noises, ranging
from a buzzing to a loud knocking. You will be given earplugs to diminish
the noise.
Because an MRI exam can take images or “slices” from
various angles, several sequences or sets of images will be taken. Each
sequence will last from one to 10 minutes, and the technologist will
inform you before the scanning noise begins. The total exam time for an
abdominal or pelvic scan can range from 30 to 90 minutes. You must lie
very still during each sequence, in order to produce clear diagnostic
images. For some sequences, you may be asked to hold your breath for a
short time.
Depending on your symptoms or prior medical history,
you may be given an intravenous or
contrast
agent for your scan. The technologist will explain this procedure to you
if it is necessary.
Patient preparationYou
will need to refrain from eating or drinking for two hours before your MRI
appointment. Because the MRI uses a very large, strong magnet, you will be
asked to remove and store any loose metal, such as jewelry or keys. You
may be asked to change into a hospital gown.
Side effects
and complicationsMagnetic resonance imaging does not cause
any known long-term side effects. You may experience temporary ringing in
the ears, similar to the sensation following a loud music concert. The
earplugs should minimize this. While MRI examination has no known effects
upon a fetus, please let the staff know if you think you may be pregnant.
In some cases, your scan may be modified or rescheduled later during your
pregnancy.
Follow-up careNo follow-up care is
necessary after an abdominal MRI scan.
