[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.

[Role of digital X-ray study in the current diagnosis of gastric cancer].

The authors attempted to assess and provide evidence for the expedience of using a digital radiography CR system in clinical gastroenterology. The prerequisite for this was the results of large-scale diagnostic studies of different organ and systemic diseases. The authors underline the specific features of application of this digital system: the latter allows several analogue X-ray apparatuses to be transformed to digital ones, provides economic efficiency as compared with apparatuses with the direct digitization of an image, shows telemedical prospects, and has low radiation loads as evidenced by research and experimental studies even in comparison with green systems, which makes the use of these digital systems in X-ray gastroenterology highly tempting.

[To the ways of the most reasonable implementation of digital radiography into the practical public health of the Russian Federation].

The main idea of the authors' paper is to propose the most reasonable way of actively introducing the digital principle into the traditional roentgenological section of radiation diagnosis. For this, a luminophore digital radiography system has been chosen. The authors of the paper give a full-scale assessment and appropriate recommendations for its use.

[Role of computed tomography in every day practice of municipal health care of the Russian Federation].

The basic idea of the paper is due to its authors' wish to provide a comprehensive objective assessment of the role and place of currently available technologies of radiation diagnosis in municipal health care of the Russian Federation on the basis of the computed tomography (CT) room of the Stupino Central Town Clinical Hospital that performs the function of the leading medical institution of the whole Stupino District, Moscow Region. The paper presents a detailed characterization of the basic lines of CT studies and an analysis of their scope in a great variety of clinical subunits of the multidisciplinary Stupino hospital offering 795 beds. The paper lays a great emphasis on the particularly organizational aspects associated with the CT diagnosis of different diseases at the level of municipal heart care.

[Some problems of radiation diagnosis of colon cancer].

The paper gives the view of the author who is based on his many-year experience in studying a role of radiation diagnosis of colon cancer. It shows it necessary to enhance the significance of radiation diagnosis. More attention should be given to the traditional section on the current radiation study of the large bowel: to irrigoscopy and single double contrasting.

[Organizational and methodological approaches to using digital X-ray fluorography in the diagnosis of lung diseases in practical public health care of the Russian Federation].

On the basis of a great body of information, the authors propose the most reasonable and effective organizational and methodological approaches to further actively introducing digital lung fluography into Russia's practical public health care. The paper discusses a diversity of topical problems associated with the practical use of digital X-ray fluorography (DXF), such as the assessment of its use depending on the level (municipal or regional) of public health care, methodological issues of its performance, current relationships of DXF and film fluorography; a place of DXF in the screening and routine clinical diagnosis of lung diseases. Great emphasis is laid on the role of DXF in the diagnosis of tuberculosis and cancer of the lung.

[New capacities of roentgen diagnosis in detecting small intestinal pathology].

The paper based on the data of more than 200 studies of the small bowel with the new agent Entero-VU specially designed for X-ray study of the bowel gives an objective evaluation of this agent. The authors of the paper analyze the capacities of Entero-VU in diagnosing 38 cases of Crohn's disease, tuberculosis and tumors of the small bowel. Moreover, as a separate section the paper provides an assessment of the agent in mapping the X-ray standards of the small bowel.

[A role and a place of ultrasound diagnosis of acute ileus].

The main purpose of the authors is to present their view of a place of present-day ultrasonography in the diagnosis of acute small and large intestinal obstruction. A comparatively sizable material covering 218 verified cases of acute ileus, including 77 patients with large intestinal obstruction and 141 patients with impaired passage of the intestinal contents along the small bowel was used to outline the aspects of ultrasound techniques and the symptomatology of ileus, by differentiating its some types. Along with the general assessment of the methodological and semiotic aspects of ultrasound diagnosis of acute uleus, the authors emphasizes a role of sonography in the detection of large intestinal obstruction by outlining their modified procedure of ultrasound irrigoscopy.

[A place of digital X-ray fluorography in the detection of lung diseases in the public health facilities of the Russian Federation].

The paper shows the authors' opinion as to the use of digital X-ray fluorography (DXF) to detect pathology of the lung, primarily its tuberculosis and cancer from organizational-and-methodological and purely diagnostic standpoints. Based on a great body of data pooling 21,295 studies of patients, which comprised two (screening and routine clinical) groups, they authors state their views on the place and role of lung DXF in the work of public health facilities in the Russian Federation (RF). The objectivity of the authors' opinion is confirmed by the different nature of a lung abnormality detected by DXF at both the municipal and regional levels of the RF public health system and by a comparative analysis of the findings with those of film fluorography, routine X-ray study, linear tomography, X-ray computed tomography (XCT), and surgical evidence.

[Magnetic-resonance tomography in diagnosis of hepatopancreatoduodenal tumors].

Results of magnetic-resonance tomography (MRT) in 112 patients with diseases of hepatopancreatoduodenal zone were analyzed, 24 of them had tumors of bile ducts and pancreas. New noninvasive diagnostic method--magnetic-resonance cholangiopancreatography (MRCPG)--performed in addition to routine MRT was evaluated. The technique of MRCPG, analysis of results, manetic-resonance semiotics are presented.

[A place of outpatient screening in the formation of a current organizational scheme for better radical detection of breast cancer].

The authors consider it necessary to revise the current views of breast cancer in women. In their opinion, excessive consideration of mammography as an independent section of radiation diagnosis does not contribute to better detection of breast cancer. The principle of including mammography into the general traditional section of current radiation diagnosis should be regarded as of paramount importance.

[Cancer of the upper stomach: current problems of its diagnosis].

Data on 1248 cases of stomaches radically operated on for cancer at the surgical departments of the Moscow Regional Research Clinical Institute in 1971 to 2000 were used to study a number of problems associated with cancer of the upper stomach, by regarding the present-day role of radiation diagnosis as of paramount importance. The following radiation diagnostic techniques were assessed. Among them there were traditional X-ray studies (in each case), the new radiation diagnostic techniques: ultrasound study and computed tomography (CT) (750 studies), magnetic resonance imaging (MRI) (120 studies).

[New capacities of X-ray diagnosis in detection of small intestine pathology].

The paper based on the data of more than 200 studies of the small bowel with the new agent Entero-VU specially designed for X-ray study of the bowel gives an objective evaluation of this agent. The authors of the paper analyze the capacities of Entero-VU in diagnosing 38 cases of Crohn's disease, tuberculosis and tumors of the small bowel. Moreover, as a separate section the paper provides an assessment of the agent in mapping the X-ray standards of the small bowel.

[Outpatient screening and its place in better detection of breast tumors].

The authors state their opinion on this problem by analyzing their 5-year use of their programme specially developed for detection of breast disease, mainly cancer, among females visiting specialized rooms of non-mammological profiles (gastroenterology, endocrinology, rheumatology, pulmonology, neurology, cardiology, hematology, nephrology, etc.) in the consulting polyclinics of regional (territorial) hospitals and large city hospital-polyclinic complexes. In this period, mammographic studies were made in 9169 women included into a breast cancer-risk group.

[Current X-ray diagnosis of stomach cancer (comparison of radiologic and morphological methods of investigation)].

By using the principles of wide comparisons of the data of radiation diagnosis (routine X-ray study, ultrasonography (USG), CT, MRI) with the morphological findings of resected gastric specimens from patients with endophytic gastric cancer (EGC) (n = 85), the authors propose some points in the problem associated with its diagnosis. They believe that by taking into account the fact that there is an obvious growth of endophytic parietally growing gastric cancer with the concurrent reduction in its intestinal forms, it is necessary to restore current radiation to its leading place, along with endoscopy, in detecting the cancer. The authors makes a highly positive assessment of USG, CT, MRI in addition to routine X-ray study and endoscopy particularly in those cases when difficulties emerge in histological verification of the existing signs of parietally growing cancer.

[Place of digital X-ray fluorography in improving the diagnosis of pulmonary tuberculosis, lung cancer and mediastinal pathology].

The prime objective of this paper is an effort to make a comprehensive assessment of a place of current digital X-ray fluorography in the diagnosis of various diseases of the lung, primarily its tuberculosis and cancer, and abnormalities of the mediastinum. The investigation used a principle of obligatory examination of the diagnostic potentialities of film X-ray study and digital X-ray fluorographic findings. Assessment of digital X-ray fluorography showed its potentialities of identifying an abnormality just on the monitor screen and through printer (paper) image reproduction.

[Current problems in the diagnosis of gastric cancer].

Based on their own long-term experience in diagnosing gastric cancer and by taking into account the fact that clinicians and diagnosticians analyze this problem insufficiently objectively, the authors of the paper try to convince the reader that it is necessary to revert to the problems of its diagnosis again. They proceed from recent new reports on gastric cancer pertaining to both its morphological forms and diagnostic capacities wherein current radiation diagnosis requires its active return to the problem of its detection. This standpoint of the authors is based on the date of over 6000 comprehensive studies of the stomach, of them 2800 cases have been diagnosed as having tumor lesions.

[Ultrasound study in the diagnosis of colon obstruction].

The authors present the results of their investigations into the use of routine transabdominal sonography and ultrasound irrigoscopy in the diagnosis of acute colon obstruction in 70 patients. In 55 patients, the cause of this pathology was tumor-induced obturation of colon lumen and in 15 cases, the pathology resulted from colon evacuation dysfunction due to congenital abnormalities, acquired stenosis due to inflammatory diseases. Ultrasound irrigoscopy was first applied to determine the presence and degree of colon obstruction and to establish its causes.

[Current x-ray diagnosis of Crohn's disease of the small intestine].

The paper evaluates the potential for x-ray diagnosis of Crohn's disease of the small intestine in 18 patients using the new barium contrast medium Entero-VU intended for examination of the small intestine. The authors provide a detailed description of the examination technique, x-ray appearance of Crohn's disease and make a comparative analysis of the diagnostic potential for the use of the common barium suspension and the contrast agent Entero-VU. The cases of Crohn's disease analyzed in the paper encompass its different stages and sites in the small intestine.

[Magnetic resonance cholangiopancreatography and a problem in diagnosis of hepatopancreatoduodenal diseases].

Based on the findings of 54 magnetic resonance studies, the authors used 19 of them authors to study the types of normalcy. A role of the new noninvasive technique magnetic resonance cholangiopancreatography (MRCPG) in the diagnosis of hepatopancreatoduodenal diseases is assessed. The potentialities of MRCPG in the detection of most common diseases and malformations of the biliary system are demonstrated.
