MRI-magnetic resonance imaging uses a combination of magnetism, radio waves and computer processing to create detailed images of nearly every body part and internal structure - from bones and joints to vital organs and tiny blood vessels in the brain.  Unlike imaging techniques based on x-ray, with MRI there's no exposure to radiation. It is among the safest and most versatile of imaging methods. We use protocols and procedures developed specifically for babies and children, which means age-appropriate care for your child and the best possible images for the radiologist.

Physicians order MRI studies to rule out or diagnose disease or treat the following:

• Cysts, tumors and cancer throughout the body
• Seizures and headaches
• Birth defects
• Certain heart problems
• Diseases of the urinary tract and digestive system
• Skeletal deformation

Safety

The magnetic field and radio waves associated with MRI scanning pose no health threat or safety risk. The magnet does not touch or hurt your child. Tell you physician if your child has any metal or electronic object or implanted medical device, such as a cochlear implant, in his/her body. The strong magnetic field can cause metal devices to move, which can be dangerous.

What to Expect

Before the Test

If the procedure is planned with sedation or anesthesia to keep your child still during scanning, you may be instructed not to give him/her food or drink for several hours before the test. Have your child wear loose-fitting, comfortable clothes without metal buttons, zippers, buckles, studs or jewelry. Metal scatters the magnet's energy and produces unclear pictures. A gown will be provided if clothes interfere with the test.

During the test

MRI exams are painless and take between 30 and 60 minutes to complete, depending on the body part being scanned. If necessary, your child will be given a mild sedative for relaxation and to help him/her lie motionless during the MRI scan. We have a highly experienced team of pediatric sedation nurses. Our staff is also skilled at helping young children stay motionless for imaging studies by employing age-appropriate distraction techniques.

If your child is awake during the procedure, he/she will hear rather loud, rhythmic tapping and thumping noises caused by the machine's magnetic field. The technologist will be able to see your child through a window and talk with him/her throughout the procedure to let him/her know when the noises will occur and how long they will last. You can stay with your child in the scan room, but please leave all metal objects outside the room, including keys, jewelry, credit cards and all electronic devices.

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 sedation was used during the test, your child may want to sleep. This is normal. If the site of any intravenous injection becomes swollen, red or painful after 1-2 days, please call your doctor. 

The Results

Once obtained, your child's MRI images remain an electronic file. Florida Hospital has the most sophisticated network, viewing stations and software for processing, transmitting, reviewing and storing these electronic images.

One of our board-certified pediatric radiologists will examine and interpret the MRI scans and create a report of his/her findings that will be sent to your child's doctor. Your child's doctor will present the results and discuss them with you.
