Can iMac 5K retina be used in place of Barco 3 MP or Eizo 3 MP screens for reading medical x-rays ?

[iMore Question]

I need such a 3 MP screen for daily reading emergency rooms x-rays and the iMac 5K is much cheaper than Barco screens...

Ugh . . . I believe it's more complicated than that. Don't you have to worry about things like accuracy under different lighting conditions?
