The disclosure of the human genoma, the progress in understanding of diseases on molecular and cellular levels, the discovery of new disease-specific targets, and the development of new medications will revolutionize our understanding of the etiology and the treatment of many disease entities. Radiologists are faced with a paradigm shift from unspecific to specific molecular imaging techniques as well as with enormous speed in the development of new methods and should be enrolled actively in this field of medicine.
