Hatfield,
Not sure of your connection with Emory or your source of information, but thankfully, your answer is no longer accurate!
There is a PACS system that is on par with any other for MRIs and CT scans. As for plain radiographs, the trauma bays now have digital x-ray machines that upload to PACS. You would be correct regarding plain films done for non-trauma patients in the ER as well as inpatients/outpatients, as these are still in hard-copy format. Orthopedics does also have its own mini C-arm machine.
I hope this clears things up a bit...
