What is an MRI machine?
The MRI machine uses a large mag­net to take pictures of the inside of the body. A MRI provides important informa­tion about our health.We encourage parents to be present during examination of a child.

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.

What are some of the words we will hear about MRI?
Contrast material: a liquid that helps producing a better picture during the exam and is given intravenously (IV Gd-DPTA); it is to be noted that allergic reaction are extremely rare.
Sedation: sometimes medication is given by mouth or through an intravenous injection, so that the child will go to sleep for the exam. Sedation may be used for those children who cannot lie still during the exam. Patients who are sedated will have to stay until they are fully awake.

 
 
 
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).
