See Chris Nze's work for medical xray film inspiration (Agfa Curix double sided and some Kodak I don't remember the ID for). You may have to PM him to ask which images are on xray film.
He doesn't like response outdoors so does still lifes with it indoors and gets high ISO with dilute Rodinal.
He does Pt/Pd with it and on a PC monitor they look great. We are not on the same continent, so I have not seen his prints, but I have no reason to doubt he has conquered any problems with double-sided xray film. He says the 2nd layer helps attain adequate contrast, and he only does ULF contacts with it.
