MRI Scans

 

 

What is an MRI?

Magnetic Resonance Imaging (MRI) uses an incredibly powerful magnet. The magnet generates information

that a computer uses to construct very detailed cross sectional images of the body.

 

An MRI scanner does not use X-rays so there is no radiation.

 

You must bring your Request form

We can't legally perform a scan without a Request form from your Doctor, so you must bring this with you.

We also need your Medicare card and any old films or CDs you have of previous scans. 

 

Some people can’t have an MRI

The powerful magnet means the following people may not be able to have an MRI scan:

 

  • Anyone with a pacemaker

  • People with metal clips on blood vessels e.g. from heart or brain surgery

  • Patients who have been metal workers or have had injuries to their eyes

  • People with certain types of implants

  • Women in the first trimester of pregnancy

 

It is important that you tell the receptionist when you book if you think you might fit any of these categories.

 

Our staff will also ask you detailed questions about your medical history before your appointment.

 

What will happen when I arrive?
When you arrive at reception, one of our friendly staff will escort you to the MRI suite where you will be asked to complete
the medical history questionnaire. Our staff will be available to answer any questions you have about the procedure. You will then be asked to change into a patient gown and remove all your jewellery.

 

The actual MRI is conducted by a highly trained technician called a Radiographer.

 

The scanner is noisy so we will give you earplugs to make you more comfortable.

 

The actual scanning takes between 20 and 60 minutes. It is best to allow an hour for the questionnaire and scanning to be completed.

 

MRI Contrast (Dye)

Sometimes an injection of MRI Contrast (a special dye) may be given into your arm. If you need this, the Radiographer will discuss this process with you.

 

IMPORTANT: If you are allergic to anything, or think you could be pregnant, please tell the Radiographer BEFORE your scan. 

 

If you have any questions about your MRI please phone our friendly receptionists at any time.
