What to bring

  • Your request form
  • Any relevant previous imaging
  • Your Medicare card

Preparation – On the day of the scan

  • You will be asked to fill out a MRI Safety Check list to confirm you do not have any contraindicated items or implants in/on your body. The MRI Technologist will ensure that no potentially unsafe items enter the scan room.
  • You will be required to wear earplugs during this scan.

B. During your MRI TM Joints scan


You will be required to lie very still for the duration of the examination and to wear earplugs during this scan. The MRI scanner will make various loud tapping or buzzing noises during your scan. These run for 2?5 minutes at a time and the MRI technologist will communicate with you between these scans.

The MRI scanner at Envision is currently WA’s least claustrophobic scanner. The wide magnet bore (the part you lie in) is also the shortest in Perth, making it a far more comfortable experience for you, compared with other MRI scanners. Generally, most pictures will be done with your mouth closed. The last sequence of pictures requires you to have your mouth open, biting on a splint. This allows visualisation of the TMJ’s and surrounding structures in the open position.

Your scan will take approximately 30 minutes.

Risks and side effects

An MRI Scan is a very low-risk procedure. There are no known adverse health risks associated with the magnetic field or the radio waves used by the machine. Patients with certain contra-indicated devices may not be able to have an MRI scan.
