Diagnostic imaging, scans and X-rays in Australia
In Australia in 2017-18, health professionals performed more than 27 million diagnostic images that were funded under Medicare.
Images are created using:
- radiation — X-rays (including mammography), CT scans, PET scans, nuclear medicine
- sound waves — ultrasound
- magnetic fields and radio waves — MRIs.
A radiologist (or other medical practitioner) interprets the images and reports this information to your doctor.
What we’re doing about diagnostic imaging, scans and X-rays
Service providers need special equipment and training to interpret diagnostic images
Our work on Medicare helps to reduce the cost of diagnostic imaging services so more people can afford them. Medicare also requires that:
- equipment is kept up to date
- diagnostic imaging practices are accredited
- staff are properly trained.
Initiatives and programs

The Diagnostic Imaging Accreditation Scheme (DIAS)
Diagnostic imaging practices must be accredited through the DIAS. The scheme makes sure that safety standards are followed, equipment is maintained and staff are registered and/or licensed.
Law

Health Insurance Act 1973
This Act and its subordinate legislation governs the payment of Medicare benefits for diagnostic imaging services in Australia. The Act and related regulations, such as the Diagnostic Imaging Services Table, can be found on the Federal Register of Legislation website.
