MRI
preparation
|
|
 |
You
(or your child) will have to be able to
lie still for 15-35 minutes. |
 |
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 3-4
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. |
The
M.R.I (Magnetic Resonance Imaging) machine contains
a powerful magnet which can attract ferromagnetic
metallic objects. These objects may also disturb
the images. Accordingly, please note the following:
 |
Patients
with cardiac pacemaker and those with
metallic implants (such as aneurysmal
clips) or intra-orbital metallic foreign
bodies are exempted from the study. |
 |
Please
inform the Doctor about your previous
operations particularly if there are metallic
implants. |
 |
Please
get rid of the following items before
the examination (jewels, metallic currency,
keys, watches, bank credit cards, eyeglasses,
hearing aids, artificial denture, hairpins,
etc..). Keep these items and other personal
belongings with a relative or let them
with the technician doing the MR examination. |
 |
Small
metallic things with your dresses like
buttons or zippers are not allowed, kindly
put-on our hospital gown supplied for
you during the examination. |
 |
The
examination takes about 15-20 minutes
(divided into 3-4 periods of time) |
 |
The
examination is painless and doesn't use
ionizing radiations. |
 |
You
will be lying down on your back during
the examination and should not move as
movement may necessitate repeating the
imaging and prolonging the study. |
 |
During
the examination the machine produces knocking-like
high sound which is normal. Rubber ear-plugs
are available, if needed you can ask for
one. |
 |
The
Doctor and technician performing the study
are continuously monitoring you and they
can communicate with you throughout the
examination through the intercom. A relative
or a companion can stay with you inside
the examination room during the study
if necessary. |
 |
Patients
suffering from severe pain preventing
them lying down quite during the examination
may be given sedation and this necessitates
being fasting at least 4-5 hours prior
to the examination. Other patients do
not need to be fasting. |
 |
No
definite scientifically proven dangers
or side-effects to this study on the fetus
or pregnant woman. However, the study
is not routinely used during pregnancy
except whenever it is indicated. |
|
|
|
|

the patient, if any. |
 |

 |
Blood
pressure should be checked. |

 |
Patient
better to hold micturation 2 hours before

For infants:
| Patients
need to arrive with a full bladder. Give
your child liquids 30 minutes to an hour
before the ultrasound. Do not let your
child drink Coke, Pepsi or any other soft
drink. Do give water, juice, milk or formula.
If your child is an infant, please give
lots of liquid before arriving and bring
extra bottles. |
How should I prepare my child?
| Although
you cannot explain the exam to your baby
your voice and comments will help your
baby feel more secure during the test.
Bringing along a special blanket, toy
or pacifier, and also a bottle of juice
or formula to feed your baby when the
test is done. |
Toddlers and preschool-age
children
| Young
children remember things for only a short
time, so the best time to talk about the
test is right before you are ready to
come to the center.
Tell your child that you are going to
the center to have some "pictures"
taken of inside his body. Explain that
the doctor needs them to help him/her
get better. Try to use simple words.
It is important to be honest with your
child. If the test is known to bring some
discomfort, be sure to mention it and
tell the child it is okay to cry.
Because children at this age are afraid
of being separated from their parent,
say that that mummy or daddy will stay
beside as much as possible. When you come
to the center, bring a favorite book,
toy or blanket. You may also bring along
a snack for after the test. |
School-age children
| School-age
children have a strong imagination. If
you don't tell them the truth about what
is going to happen during the test, they
might imagine something much worse than
the actual test.
The day of the test, tell your child that
he will be going to the hospital to have
some pictures taken of the inside of his
body. Tell him the pictures will help
the doctor decide how to make him better.
Use simple words. Be honest. Try to tell
your child exactly what will happen. If
your child's examination is going to hurt
a little, be sure to tell him it's okay
to cry. When you come to the center, bring
along a favorite book or game. If you
wish, you may also bring along a snack
for after the test. |
