The presence of a chapter on such a nebulous topic may seem an intrusion in a book devoted to radiology—of all medical disciplines, that most deeply indebted for its origins to physics, and still intimately dependent for its continuous development on the technology of light, heat and sound. I shall add to the shock by introducing my theme with somewhat allegorical talk, hoping to turn your thoughts into unaccustomed grooves. But be patient; allegories (pictures in which meaning is symbolically represented) are no strangers to radiology. The raw data of this subject are pictures, images; and you may be working with several different kinds of images of the same thing. You will need to learn their codes: not only how they were made, so that you can recognize what they represent anatomically, but what they mean (allegorically), what inferences they can help you to make about the patient’s health or sickness.
