[Imaging diagnosis in border-less age].

: Several proposals were made under the title of imaging diagnosis of border-less age. One was the wide range of application of multimedia in medicine. The application is in the world wide scale, such as information super highway, and information technology vision 2000, and so forth. Second and third proposals were to promote clinical and basic research groups beyond specialities to make micro and micron imaging possible both in morphology and function. As an example, imaging of interstitium of the bone marrow by magnetic resonance microimaging was discussed. To convey these concepts, multidiscipline and inter- and intra-speciality work is mandatory. Finally, PACS and telecommunication were introduced as one of the tools of imaging diagnosis in border-less age with illustration of PACS system at Saitama medical school.
