Magnetic Resonance Imaging (MRI) System Market worth $5.24 B

The global healthcare industry is witnessing a paradigm shift, skewed towards non-invasive and non-ionizing diagnostic procedures, which not only cures serious illnesses, but also have negligible side effects. Magnetic resonance imaging (MRI) is one of such technologies with the potential to revolutionize medical diagnostics in healthcare. The global MR systems market was valued at $4 billion and $4.1 billion in 2011 and 2012, respectively. As of March 2013, the market is expected to be $4.13 billion and is poised to reach approximately $5.24 billion by 2018 at a CAGR of 4.56%.
