My favorite is when the pt is either AMS, or just severely combative/uncooperative. Usually as techs, we know to ask for some light sedation… or even heavy sedation to help us get some sort of readable study. We always get push back on the fact that they can’t monitor the pts mental status if they are sedated. Yet they can’t make a proper treatment or know if anything is going on if we have garbage studies. So idk…. Pick your poison. Im not a dr, but i know the quality isn’t going to help with a definitive rule out.

They usually come back within 2 hrs and the pt is fully sedated or enough that they don’t move an inch for the scan. Why waste the radiology time slots in the first place…. Just do it right the first time..
