Radiologic technology in gastroenterology: "old" and "new" in the diagnosis

The history of the development of methods of radiologic imaging in gastroenterology decades and represents, basically, the evolutionary transformation of contrasting methods of study of the digestive tract. Classical research methods of the stomach, colon and small intestine with contrast still remain relevant to the present time, as represent the most simple and physiological way of obtaining information on the morphology and function of the digestive tract, both in normal and in pathological conditions, including postoperative changes. Fluoroscopy of the stomach and duodenum ulcer, barium enema was initially performed using only barium suspension. Then, techniques have improved through the use of double contrast techniques. To improve imaging of the digestive tract significantly contributed to the improvement of x-ray equipment, namely, the appearance of electron-optical image converters. Absolutely new stage in development of radiation technology in gastroenterology has become computerized tomography that provides a revolutionary leap forward not only in diagnostic systems, but also in all clinical disciplines that use the information to determine the optimal tactics of conservative treatment and selection of adequate operative approaches in various clinical situations.
