[Use of CR in the detection of present gastric cancer: diagnostic aspects].

The authors describe the state-of-the-art of gastric cancer detection in detail and show the current principles of its radiodiagnosis. They provide a detailed explanation for that radiodiagnosis should be urgently returned into gastroenterology as an equal with endoscopy, which is based on the existing tendency for the major morphological types of gastric cancer to appear. The present-day capacities of radiodiagnosis of gastric cancer are mainly based on the introduction of the digital technologies into traditional radiology, which will replace the analog imaging principle in the foreseeable future.

[Roentgen diagnostics with the emphasis on it's traditional roentgenological method is a major sourse to improve gastric cancer diagnosis].

The main idea of the article is presentation of todays problem of gastric cancer diagnosis. Authors, supported by long-term experience of gastric cancer diagnostics, demonstrate the necessity of the return of traditional roentgenological method for it's diagnostics, along with endoscopic technique. In the first place it is determined by the increase of sclerotic and mixed forms.

[To differential diagnosis of esophageal cancer and other diseases with the similar clinical symptoms, by using traditional X-ray study].

The principal purpose of the paper is to assess the role of the X-ray section of current radiation diagnosis in obtaining objective information and interpreting it in esophageal cancer. The study was methodically based on its serial studies, by comparing the data of clinical, radiation, and endoscopic diagnosis with those of morphological studies of the biopsy specimens taken at resection for cancer of the esophagus and the upper stomach, and histologically examined them in diseases running with the similar clinical symptoms. The complex of radiation techniques included traditional X-ray study (compact filling, double contrasting).

[Radiation diagnosis of tumors at four sites (the lung, breast, stomach, and large bowel) in the organizational and methodological standpoints of practical public health of the Russian Federation].

The basic idea of the paper is to put forth today's vision of detecting tumors at four sites (cancer of the lung, breast, stomach, and large bowel) at the level of municipal and regional public health systems. Based on their many years' experience in "contacting" this pathology, the authors characterize the role and significance of basic radiation techniques applied to each of these four tumors, which should be used in their diagnosis. The authors also underline the need for reasonably certifying radiation diagnostic apparatuses for municipal and regional public health systems, which would efficiently combine their diagnostic and economic profitability, which will be able to avoid materializing the potential of expensive radiation equipment by just 15-20% of its built-in efficiency.

[The modern role of stomach cancer radiodiagnostics].

The authors' main purpose was to assess the role of stomach cancer radiodiagnostics, considering the changes in the morphology of the disease within the last decades of the 20th century. The results of radiodiagnostic and morphological study of 1258 cases of verified stomach cancer were compared. This methodical approach allowed correction of radiodiagnostic methods and stomach cancer semiotics, directed towards detection of endophytic tumors.
