Comparison of True Technical Costs of MRI and CT

Detailed analysis of the multiple variables that contribute to the cost of operating a single 3T magnet was undertaken including capital costs, consumable costs, overhead costs, staffing costs and maintenance/service expenses. The cost per minute of MRI is linear at $3.13 with a prominent increase at 10 minutes accounting for the point of contrast injection, which is the largest incremental cost for an MR exam. The cost of a 15 minute MRI with contrast is $106 versus $99 for a 5 minute CT with contrast (cost is comparable secondary to slightly higher cost of CT contrast compared to gadolinium).
