The medical field of radiology and its related disciplines, such as nuclear medicine, are not very well known among non-specialists. The awareness campaign “Radiology – understanding what’s inside” illustrates this complex medical topic in a fascinating and easy-to-understand way. This is achieved by an impressive image language and a design that clearly stands out among the average awareness campaigns in the field of waiting room communication. In addition to posters, a brochure with a CD-ROM explains the medical benefits and services.
