What
does a body MRI show?
This scan shows tissues,
muscle, cartilage, bone marrow, ligaments, tendons
and blood vessels inside the body. A MRI scan
can also give your doctor important information
about the heart, if needed.

| How
to get ready for the examination?
You (or your child) will have to be able to
lie still for 15 minutes to one hour.
If your child cannot lie still for this amount
of time, sedation may be needed. A child who
needs sedation cannot have solid foods, formula
or milk for six hours before the appointment.
Clear liquids such as water and juice without
pulp can be given until two hours before the
exam.
Sometimes contrast material is necessary for
MRI exams. If you (or your child) need contrast
material, do not eat or drink for two hours
before your appointment.
If sedation or contrast is needed, a nurse,
doctor or technologist will go over the details
with you.
Since some noises from the MRI machine will
be loud, we will offer you (or your child) ear
plugs. If your child has a favorite blanket,
you may bring it with you. Any special toy that
does not have any metal parts may also be brought
along.
|
| Who
performs the MRI exam?
The MRI technician and the radiology nurse will
give the sedation and contrast (if needed) and
take the pictures. Both technician and nurse
are under the supervision of a radiologist,
a doctor specialized in MRI radiology examinations.
|
| Who
looks at the results?
The radiologist (usually a Professor) will view
all of the pictures and then write a report.
|
| Is
there any risk from the radiation?
MRI does not use radiation to make the pictures;
it uses the magnet and radio waves to make them.
There are no known risks with MRI.
|
| What
happens after the MRI exam?
When the exam is completed, you may go home
or back to your hospital room (if you are an
inpatient).
