What is an MRI?
The MRI is a way to take pictures of the body using a large magnet, radiowaves, and a computer. The MRI does not use radiation. Energy from the magnet is transmitted into the part of the body being studied. When this energy comes back from the body, a detailed picture is made by the computer.
Procedure
The scan room contains a tunnel-shaped magnet. The tunnel is just big enough to hold a cot where your child will rest while pictures are being taken. The magnet will not touch or hurt your child.
Getting ready for the test
Children may not eat up to 8 hours before the test and may not have anything to drink 4 hours before the test. Your child should not wear clothes with metal buttons, zippers, buckles, studs or jewelry. Metals scatter the magnet's energy and produce unclear pictures. A gown will be provided if clothes interfere with the test.
The MRI
Your child must lie very still for 30 to 90 minutes and a mild sedative may be given for relaxation. If your child is awake during the test, he may hear a series of very loud noises, such as hums, knocks, beeps and clicks. These are normal sounds of the testing machine. The technician will be able to talk with your child and tell him when the noises will occur and how long the sounds will last. Parents are welcome in the scan room. Please leave all metal objects outside the room, including keys, jewelry, credit cards, beepers, cell phones, and portable computers.
After the test
When the test is over, depending upon specific instructions from your child's physician, your child may eat regular meals, play and go to school. If he has had medicine to help him relax, he may want to sleep. This is normal. When he is fully awake, he may eat and play as before the test. If you have any questions, you may ask the MRI technician or your child's physician.
