The availability of MRI units has rapidly increased over the past decade, especially in most countries from the Organization for Economic Cooperation and Development (OECD). Japan has the highest number of MRI scanners per capita, followed by the United States. 

Both brain and spine studies make up more than 50% of all studies performed with MRI, whereas heart and interventional studies accounts for less than 5%.

Cardiac Magnetic Resonance (CMR) is a rapidly emerging non-invasive imaging technique providing high resolution images without the use of ionizing radiation. In developed countries, CMR is becoming a more important exam, frequently performed in clinical practice. Just in the UK, 60 centres provided CMR services in 2011, performing 1000 scans per million population per year. CMR requirement are around 2200 scans per million adult population, and an upper limit of 44,000 scans per year. A minimum activity level is needed for quality – a minimum of 500 scans per year is recommended.

Two world-wide surveys were and are carried out to assess CMR impact in clinical care. The EuroCMR registry and the GCMR registry. If you want to read more about these studies, you can access to the links below.
