A lot of people get blasted with obsene amounts of ionizing radiation so the insurance pool can save a few bucks over an MRI. Disgusting.

  It's not necessarily a cost issue. CT scanners have higher spacial resolution for angiography.

    Interesting. How often are head CT's without contrast ordered following concussion? How often should they have been MRI's?
