Here are some shots taken on a Mamaya C330 with a single exposure back and mammography x-ray film. The single exposure back takes film holders and of which I have 3. So you cut the film to size in a darkroom under a safe light (the film is orthochromatic - insensitive to red light) and load them into the film holders which can in turn be loaded into the single exposure back in daylight. There's no reason though that x-ray film can't be cut and placed directly inside any camera in the darkroom. Mammography film, unlike normal x-ray film, has its emulsion on one side only, so there's less chance of it getting scratched. It also has better resolution, I believe.
