I don't think you can get a DICOM-certified display at 5K and 27" for half the price. Probably like $1k less but that's it - and if you're a radiologist making $300k+ you're not going to want to cheap out on a display.
If you're a radiologist making $300k+ you're going to want to use certified displays so that you don't get sued for using non-approved devices for diagnostic use, and that's going to cost you maybe $6k for a 21" monitor.
