The French government plans to install MRI facilities dedicated to musculoskeletal indications. We have analyzed the use of imaging investigations in the community to assess their market share.

We undertook a retrospective analysis of all reimbursements during the year 2012 by the French Social Plan for Independent Workers for 4 imaging methods for a musculoskeletal indication (MRI, CT scan with or without opacification and contrast-enhanced conventional radiography).

Three hundred and thirty-two thousand eight hundred and ninety-three beneficiaries were included. The following investigations were used: MRI 12659 investigations; CT scan without direct opacification 7392; CT scan with direct opacification 1271; contrast-enhanced conventional radiography 1187. Of those beneficiaries who underwent investigations of the spine, 39.91% had MRI alone, 8.62% had both MRI and one of the other investigations and 51.46% did not have MRI. The corresponding figures for beneficiaries undergoing lower limb investigations were 79.57%, 4.53% and 15.90% and those for beneficiaries undergoing upper limb investigations were 35.49%, 6.56% and 57.94% respectively.

In terms of the numbers of investigations, our results show that in France MRI dedicated to musculoskeletal indications has a wide market share for the spine, upper and lower limbs.
