If you have any of the following you may not be able to have a scan:

  • Heart Pacemaker
  • Foreign Metal Objects in Eye
  • Neurostimulators
  • Shrapnel or bullet wounds
  • Aneurysm Clips
  • First 3 months of Pregnancy
  • Cochlear Implants
  • Permanent Eyeliner

If this applies to you, you must telephone the Centre since it may mean that MRI is not a safe examination for you. This will ensure that you do not make a wasted journey to our Centre.


Occasionally the Radiologist will require the use of a contrast medium called Gadolinium. This is to demonstrate certain features in a scan and may be given intra venously or into a joint. Allergic reactions are extremely rare.
