 We discussed the recent advances in gastrointestinal radiography.

 Digitalization has been used for the last 10 years. Four million pixel image intensifier digital radiography has almost the same resolution as the conventional film-screen system. DR has lots of merits in gastrointestinal radiology, namely, decrease in patient exposure, image processing, real time acquisition of image, sequential exposure and so on. Furthermore,FPD(flat panel detector)has been developed. FPD is a completely new system, which not only provides all the advantages of DR, but also conquers most of its disadvantages.

 In the barium suspension method, the high-density low-viscosity type has become popular in the last five years. Consequently, regarding the examination methods of gastrointestinal tract, the double contrast technique is the one used mainly.
