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 Determination of the diagnostic capabilities of metadevices for breast MR examination in women.
Material and methods In the study, two types of metadevices for examining the mammary glands were considered – for imaging in a field with magnetic induction of 3 T and 1.5 T. 11 healthy women of reproductive age were examined, magnetic resonance images of T1 (turbo spin echo) and T1 3D gradient echo (GRE) were obtained based on the Dixon method with fat saturation. The images were evaluated by radiologists on a 5-point Likert scale.
Results The images obtained using the metadevices were characterized by acceptable and comparable absolute and relative signal-to-noise ratios comparing them to images obtained using a standard coil at the same spatial resolution and with a decrease in input power by an average of 27 times for 3.0 T. At the same time, for 1.5 T, the input power was reduced by a factor of 15.6, and the signal-to-noise ratio was increased by a factor of 2. For image quality criteria in terms of presence/absence of artifacts, the average score for the metadevice was higher than the score for the specialized coil by 3 T. For 1.5 T, this parameter turned out to be the same, which was probably associated with a lower level of artifacts by 1.5 T than by 3 T in general.
Discussion Analysis of the collected assessments of independent experts indicates that the diagnostic characteristics of magnetic resonance images of the mammary glands obtained using ceramic-based (for 3 T) and wire-based (for 1.5 T) metadevices are of a good and average level, and are comparable in terms of all criteria with standard approaches.
Conclusions The assessment of the quality of the obtained images demonstrates the acceptable quality of imaging and reflects the possibility of their application in clinical practice, taking into account ongoing improvements and optimization of the entire set of pulse sequences for MRI of the mammary glands.
