An assessment of the status of magnetic resonance imaging in health care.
An assessment of the current status of magnetic resonance imaging (MRI) was undertaken to provide input for future decisions on government support for the technology. Data on clinical use and economic aspects were obtained from recent literature and representatives of professional bodies. A synthesis of available data was made, taking account of the quality of evidence. The major role of MRI in examinations of the brain, head and neck, spine and musculoskeletal system was confirmed. There is increasing use of the technology in management of epilepsy and multiple sclerosis and in examinations of the female pelvis, and a growth of interest in magnetic resonance angiography. Several studies show that MRI is cost-effective in the investigation of a number of conditions. While formal evidence of the effectiveness and economic impact of MRI was limited, a judgement based on the literature synthesis and consideration of Australian data suggested that it would be appropriate to increase MRI services in this country. More definitive description of this technology will require well-designed and supported empirical studies.
