What is an MRI?
Magnetic resonance imaging (MRI) uses a strong magnetic field and radio waves to produce highly detailed images of the body's internal structures. It is particularly useful for soft tissues such as the brain, spinal cord, muscles, ligaments, tendons, and organs, and does not use ionising radiation.
Because of the level of detail an MRI provides, it is often used when other imaging tests have not given a clear answer or when a specific soft-tissue problem is suspected. The scanner produces loud sounds during imaging, and patients usually wear hearing protection.
When MRI is ordered
Your GP may consider an MRI for investigations such as persistent joint or spinal problems, some neurological symptoms (including headaches with concerning features or suspected nerve compression), certain sports injuries, and selected abdominal or pelvic conditions. Whether MRI is the best test depends on the clinical question and what other imaging may already have been done.
In many cases, an X-ray or ultrasound is done first, with MRI reserved for situations where more detail is needed or the problem is not fully explained.
Medicare eligibility for GP-referred MRI
Medicare rebates for MRI depend on both the type of scan and the clinical indication. Historically, most rebated MRIs required a specialist referral, but the Medicare Benefits Schedule now includes a defined list of GP-referred MRI items for specific indications, particularly in adults and children with certain musculoskeletal, spinal, or neurological concerns.
If your situation does not meet the criteria for a GP-referred Medicare rebate, your GP may either refer you to a specialist who can then arrange the MRI under a different rebate, or explain any out-of-pocket cost involved. Your GP will discuss the most appropriate and cost-effective pathway based on your symptoms and any Medicare criteria that apply.
How to get an MRI referral online
Book a telehealth consultation with a NewDoc GP and discuss your symptoms, previous imaging, and any specialist input you have already had. If your GP determines an MRI is clinically appropriate and the relevant Medicare criteria are met, the referral will be emailed to you after the appointment.
The telehealth consultation is bulk billed for eligible Medicare patients, regardless of whether the MRI itself is rebated. You can then book your scan at a Medicare-eligible MRI provider, and the imaging centre will confirm any out-of-pocket cost at the time of booking.
What to expect on the day
Before the scan, you will complete a safety screening form to check for metal implants, pacemakers, or other devices that could interact with the magnetic field. You will then change into a gown and remove jewellery and other metal objects. During the scan, you lie on a table that slides into the scanner, and it is important to stay still.
Scans typically take 15 to 60 minutes depending on the area being imaged. Some scans require an injection of contrast agent, which is administered through a small cannula. If you are concerned about claustrophobia or the noise, discuss this with your imaging centre in advance. Results are sent to your NewDoc GP, usually within several business days.
When telehealth may not be suitable
Telehealth is well suited to assessing whether an MRI is appropriate and arranging the referral. However, if you have sudden severe symptoms such as a severe headache that is worse than usual, sudden weakness or numbness, loss of bladder or bowel control, or severe trauma, you should seek urgent in-person or emergency assessment. Book a bulk billed telehealth consultation to discuss whether an MRI fits your clinical situation.
