In an emergency, junior doctors, often early in their training, will be called upon to give an opinion concerning an X-ray. This unique pocket-sized book, that uses line diagrams to explain X-rays, offers an ideal place for them to turn. Each line drawing has been composed by a professional artist and greatly assists in producing rapid understanding of an individual X-ray. The book features a double page layout, which allows explanatory text to be placed opposite the images. In addition, a schematic explanation of each observation is written in a simple but comprehensive manner so that readers can quickly grasp the material. It’s an essential text for trainee surgeons.
