[Imaging procedures in gastroenterology]

Recent achievements in fields of physics, microelectronical devices and informatical sciences opened huge possibilities of applications in medical specialities. Spread imaging over routine high-resolution instruments continue to be in focus of scientific researches varying from simple staining techniques to most sophisticated photodynamical techniques. Magnetic resonance imaging and computed tomography are radiological specialties, however; we mentioned them for promising achievements in computed data analysis and further improvements of virtual colonoscopy. During the last few years techniques of magnifying endoscopy have been improved including trials with narrow band endoscopy, autoflourescence endoscopy, elastic scattering spectroscopy and laser confocal microscopy. In many indications capsula endoscopy have been applied successfully.
