Over-using Radiography as a diagnostic method, there other safer methods for unknown problems, if they don't work. Then radiography or other X-ray based methods can be prescribed. Other radiographic problem could be that workplaces upgrade their old SF or CR systems into newer DR's, but forget to upgrade the computers they link the units with. That means even though DR is far faster than older methods, it is hindered by weak computational power. Personally these seem widespread and interesting enough, hope I helped.
