Starting with 2000 data, the number of MRI units include only those that are approved for billing to Medicare (Australia's national health program). In 1999, approved units represented approximately 60% of total units.
The number of units in freestanding imaging facilities was imputed for years prior to 2003 based on data collected in the 2003 National Survey of Selected Medical Imaging Equipment, conducted by the Canadian Institute for Health Information. MRI units in Quebec are not included in 2000.
Prior to 2000, the data include only equipment of Health Sector establishments.
The data include equipment installed in acute care hospitals and prevention and rehabilitation homes.
Equipment used in military hospitals and the health institutes of Hungarian State Railways are not included.
1990 data include only equipment in public and private hospitals.
Prior to 2000, the data include only equipment in hospitals.
The data do not include equipment in all the private sectors.
The data include equipment available in hospitals and do not include equipment in other health care facilities.
The data include devices in public sector establishments only.
Data are from the MRI Census and are comparable to the OECD definition. The devices in U.S. territories are not included.
