Magnetic Resonance Imaging – MRI

Magnetic Resonance Imaging (MRI) is an imaging technique that uses a strong magnet and radiofrequency waves to produce pictures or “images” of your internal organs and structures. Because MRI allows your doctor to see inside your child’s body from any angle with great clarity, it gives them a lot of information. The advantage of MRI over CT is the fact that it doesn’t use ionizing radiation. mrisystem
The disadvantage of MRI in children is the fact that the exam takes up to 45 minutes, during this time your child should stay immobile. In young children this will not be possible, therefore the study will have to be done under sedation or general anesthesia (this depends on the country/hospital in which the study will be performed).
Before your child undergoes an MRI study, you must let your MR physician or technologist know if you or your child has a pacemaker, surgical clips, a prosthesis, metal implants or any other metal objects in your body. Some implants (e.g., a pacemaker) may be affected by the strong magnetic field of the MRI. The radiologist will then determine whether or not  the MR examination will proceed. Any metal materials that might be affected or attracted by the powerful magnet used for MR imaging should be left at home or given to the MR staff for safekeeping. This list includes your watch, coins, keys, bobby pins, credit cards, pocket knives, etc.
