In an MRI (Magnetic Resonance Imaging) scan, complicated pictures are made by using a combination of magnetic fields, radiowaves and a powerful computer, not x-rays. This test shows up much more detail than plain x-rays.
- In an MRI (Magnetic Resonance Imaging) scan, complicated pictures are made by using a combination of magnetic fields, radiowaves and a powerful computer, not xrays. This test shows up much more detail than plain x-rays. In order to pick up the radiowaves, an aerial-like device is positioned around or adjacent to the area of the body under investigation. The whole scan can take up to 30 minutes to complete, during which time the child must keep very still. Children up to the age of five to six years usually have a general anaesthetic or sedation. If your child does require a general anaesthetic then your child should not have anything substantial to eat or drink for over six hours before and only clear fluids up to 2 hours before. Children having sedation should not be fasted prior to attending hospital
- For older children, one or both parents can be present in the scan room at all times, assuming that you satisfy our safety questionnaire. Your child may be a little frightened when inside the tunnel, but you can reassure your child that you are close, by holding onto a hand or foot. You must not take anything metal, your watch or credit cards into the room.
- For children not needing a general anaesthetic, we do not need them to be starved, however, if they are an in-patient then the ward may want them to be starved for other reasons.
- In some cases, the Radiologist may want to inject a special contrast agent or ‘dye’ to show up blood vessels. This ‘dye’ is extremely safe and should not affect your child. If your child has their own favourite music or story on a CD, then please bring it along and we can play it through the headphones, which we use to reduce the noise.
