.: magnetic resonance imaging (mri)

What is a MRI Scan?

Magnetic resonance imaging (MRI) is one of the methods we use for looking inside the body.  Instead of x-rays, the scanner works with magnetic fields and radio-waves to produce clear pictures of the head, spine or other parts of the body.  The scanner consists of a very strong magnet with a radio transmitter and receiver.  These instruments gather information which produce images that are used to distinguish normal healthy tissue from diseased or damaged tissue.

Preparation

No special preparation is required prior to the exam, unless you have been given other instructions, however, because you will be close to the magnet, please do not wear eye make-up, glitter, or jewellery. 

A questionnaire will be completed and questions relating to your medical history will be asked.

It is important to arrive 15 minutes prior to the examination time.  This is so the questionnaire can be checked and you can prepare for the examination.

  

Please Note: There are no child care facilities so if you are bringing small children/babies please bring someone to look after them.

On Arrival:

Patients are asked to change into a gown and remove all:

  • Jewellery
  • Watches
  • Hairclips
  • Glasses
  • Wallets
  • All other metallic objects

NOTE: Gold, white gold, platinum rings, (engagement/eternity) are exempt from this list.  Please phone us if you are considering having rings cut off as it may not be necessary.

A locker is provided to leave your valuables in during your scan.

The MRI procedure usually takes 30-45 minutes.  In most cases during the scan you are able to listen to the radio, or if preferred, you can bring a CD to listen to.

IV Contrast

Sometimes an injection of contrast is needed to highlight areas that may otherwise be difficult to see.  The benefit of this contrast examination outweighs the minimal risk.

Reactions of any kind, to this contrast are very rare, however occasionally it may cause headache, vomiting or nausea which is transient.  This contrast is administered with caution on patients with kidney disease. Please phone MRI staff if you have kidney disease.

Unsuccessful Procedures

If the patient decides during the procedure that they do not wish to continue, then this may incur a part-charge.  For private patients or those funded through ACC, the patient will be invoiced to cover administrative and technologist costs.  Patients must be aware that ACC do not cover unsuccessful procedures.
