Greetings, all. As the person who originated the 'economics' section, my intention had been to try and communicate some of the underlying cost structure that is relevant to discussions of the cost  benefit of MRI. I have seen this section abused, and I think that it may be wise to provide some cursory information about the costs of operation, but weed-out other comments which don't add materially to the content - as others have stated clearly in prior notes, above. However, I don't have access to information that would provide an idea of those operational costs. Anyone else?
