The editorial board is constantly replenished by experts who work in the CIS and foreign countries.
Six issues of the journal are published per year, the volume is 13.5 conventional printed sheets, 88 printer’s sheets, 1.000 copies. The journal has an identical full-text electronic version, which, simultaneously with the printed version and color drawings, is posted on the sites of the Scientific Electronic Library (SEL) and the journal's website. The journal is distributed through the Rospechat Agency under the contract № 7407 of June 16, 2006, through individual buyers and commercial structures. The publication of articles is free.
The journal is included in the List of Russian Reviewed Scientific Journals of the Higher Attestation Commission. Since 2008 the journal has been available on the Internet and indexed in the RISC database which is placed on Web of Science. Since February 2nd, 2018, the journal "Medical Radiology and Radiation Safety" has been indexed in the SCOPUS abstract and citation database.
Brief electronic versions of the Journal have been publicly available since 2005 on the website of the Medical Radiology and Radiation Safety Journal: http://www.medradiol.ru. Since 2011, all issues of the journal as a whole are publicly available, and since 2016 - full-text versions of scientific articles. Since 2005, subscribers can purchase full versions of other articles of any issue only through the National Electronic Library. The editor of the Medical Radiology and Radiation Safety Journal in accordance with the National Electronic Library agreement has been providing the Library with all its production since 2005 until now.
The main working language of the journal is Russian, an additional language is English, which is used to write titles of articles, information about authors, annotations, key words, a list of literature.
Since 2017 the journal Medical Radiology and Radiation Safety has switched to digital identification of publications, assigning to each article the identifier of the digital object (DOI), which greatly accelerated the search for the location of the article on the Internet. In future it is planned to publish the English-language version of the journal Medical Radiology and Radiation Safety for its development. In order to obtain information about the publication activity of the journal in March 2015, a counter of readers' references to the materials posted on the site from 2005 to the present which is placed on the journal's website. During 2015 - 2016 years on average there were no more than 100-170 handlings per day. Publication of a number of articles, as well as electronic versions of profile monographs and collections in the public domain, dramatically increased the number of handlings to the journal's website to 500 - 800 per day, and the total number of visits to the site at the end of 2017 was more than 230.000.
The two-year impact factor of RISC, according to data for 2017, was 0.439, taking into account citation from all sources - 0.570, and the five-year impact factor of RISC - 0.352.

ABSTRACT
Purpose: To describe the semiotics of neoplasms of small vessels of the liver according to computed tomography, to present a possible differential diagnosis
Material and methods: Patient S., 52 years old, underwent computed tomography (CT) of the abdominal cavity with intravenous contrast due to a sharp increase in liver formation before the planned surgery. According to CT data, a large hypervascular formation measuring 198×146×247 mm was detected in the left lobe of the liver. The feeding extrahepatic arteries and draining hepatic veins are significantly dilated. Newly formed vessels and aneurysmally dilated arteriovenous shunts up to 29 mm in size were noted in the structure of the formation. A hemihepatectomy was performed. According to the results of morphological and immunohistochemical studies, a diagnosis of «Neoplasm of small vessels of the liver» was made.
Results: the disease «neoplasm of small vessels of the liver» (HSVN) became known in 2016 after the publication of an article by Ryan M. Gill et al. This is a vascular tumor that occupies an intermediate position between a hemangioma and an angiosarcoma. Currently, it is believed that the disease is benign. Several dozen confirmed cases are known. Due to hypervascularity, the tumor must be differentiated from angiosarcoma, hepa- and cholangiocellular cancer, hypervascular metastasis, as well as benign tumors such as hemangioma, focal nodular hyperplasia, and adenoma. In our case, the distinctive feature of the tumor was a significant expansion of the feeding extrahepatic arteries and draining main hepatic veins, aneurysmal expansion of arteriovenous shunts in the structure and the absence of signs of invasion of surrounding vessels and organs.
Conclusion: In the differential series of hypervascular liver tumors, in the presence of pronounced arterial blood supply, the presence of arteriovenous shunts in the structure and the absence of signs of infiltrative growth, neoplasm of small liver vessels should be considered.
Keywords: computed tomography, hepatic small vessel neoplasia, HSVN
