Instructions for authors

Aim and scope
Polish Journal of Radiology is an international, peer-reviewed scientific journal that publishes first and foremost, original articles in the field of diagnostic imaging and related bio-medical disciplines such as epidemiology, public health, and medical technology. Polish Journal of Radiology is issued on a continuous basis as a primary electronic journal.

Categories of articles accepted:

Hypothesis;

Laboratory and in vitro studies;

Fundamental aspects of medical physics;

Animal Research;

Clinical research;

Development of laboratory techniques;

Product investigations;

Diagnostics and medical technology that enable presentation of research or review works in overlapping areas of medicine and technology such us (but not limited to): medical diagnostics, medical imaging systems, computer simulation of health and disease processes, and new medical devices.
Reviews and special reports - papers may be accepted on the basis that they provide a systematic, critical, and up-to-date overview of literature pertaining to research or clinical topics. Meta-analyses are considered as reviews. Special attention will be paid to the teaching value of a review paper.
Letters to the Editor for comments on a recent Polish Journal of Radiology's article. Case Reports will not be accepted.  

Ethical requirements
When reporting experiments on human subjects, authors should indicate whether the procedures followed were in accordance with the Helsinki Declaration of 1975, as revised in 2000 (concerning the ethical principles for the medical community and forbidding releasing the name of the patient, initials or the hospital evidence number) and with the ethical standards of the responsible committee on human experimentation (institutional and national). The authors presenting case studies are obligated not to disclose patients’ personal data. Regarding photographs, in case of any doubt that the picture inadequately protects the patient’ s anonymity his consent is required for publication.

Clinical trials
Polish Journal of Radiology is published in accordance with ICMJE policies and recommendations. The ICMJE requires - and recommends that all medical journal editors require - registration of clinical trials in a public trials registry at or before the time of first patient enrollment as a condition of consideration for article publication.
The ICMJE defines a clinical trial as any research project that prospectively assigns people or a group of people to an intervention, with or without concurrent comparison or control groups, to study the relationship between a health-related intervention and a health outcome. Health-related interventions are those used to modify a biomedical or health-related outcome; examples include drugs, surgical procedures, devices, behavioural treatments, educational programs, dietary interventions, quality improvement interventions, and process-of-care changes. Health outcomes are any biomedical or health-related measures obtained in patients or participants, including pharmacokinetic measures and adverse events.

The ICMJE accepts publicly accessible registration in any registry that is a primary register of the WHO International Clinical Trials Registry Platform (ICTRP) that includes the minimum acceptable 24-item trial registration data set or in ClinicalTrials.gov, which is a data provider to the WHO ICTRP.

In accordance with the ICMJE recommendations, the Editors of Polish Journal of Radiology require authors to provide all necessary information regarding the registered study when submitting the article for publication: name of the register, Main ID, Public Title, Date of Registration. The data provided by the author are verified by the editors.

Review process
Manuscripts are evaluated on the basis that they present new insights to the investigated topic, are likely to contribute to a research progress. It is understood that all authors listed on a manuscript have agreed to its submission. The signature of the corresponding author on the letter of submission signifies that these conditions have been fulfilled. Received manuscripts are first examined by the Editors of Polish Journal of Radiology. Manuscripts with insufficient priority for publication are rejected promptly. Incomplete packages or manuscripts not prepared in the advised style will be sent back to authors without scientific review. The authors are notified with the reference number upon manuscript registration at the Editorial Office. This journal operates a double blind review process. All contributions will be initially assessed by the editor for suitability for the journal. Papers deemed suitable are then typically sent to a minimum of two independent expert reviewers to assess the scientific quality of the paper. The Editor is responsible for the final decision regarding acceptance or rejection of articles. The Editor’s decision is final.

Permissions
Materials taken from other sources must be accompanied by a written statement from both author and publisher giving permission to Polish Journal of Radiology for reproduction. Obtain permission in writing from at least one author of papers still in press, unpublished data, and personal communications.

Disclaimer
Every effort is made by the Editor-in-Chief and the Editorial Board of Polish Journal of Radiology to see that no inaccurate or misleading data, opinion or statement appear in Polish Journal of Radiology. However, they wish to make it clear that the data and opinions appearing in the articles and advertisements herein are the responsibility of the contributor, sponsor or advertiser concerned. Accordingly, the Editor-in-Chief and the Editorial Board accept no liability whatsoever for the consequences of any such inaccurate of misleading data, opinion or statement.

Use of word processing software
It is important that the file be saved in the native format of the word processor used. The text should be in single-column format. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. In particular, do not use the word processor’ s options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts etc. When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns. The electronic text should be prepared in a way very similar to that of conventional manuscripts. Note that source files of figures, tables and text graphics will be required whether or not you embed your figures in the text.
To avoid unnecessary errors you are strongly advised to use the ‘ spell-check’ and ‘ grammar-check’ functions of your word processor.

Abstract
A concise and factual abstract is required. The abstract should state briefly the purpose of the research, the principal results and major conclusions. References should be avoided, but if essential, then cite the author(s) and year(s). Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself.

Key words
Please provide a 3-6 key words (MeSH), using British spelling and avoiding general and plural terms and multiple concepts (avoid, for example, ‘ and’ , ‘ of’ ). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These key words will be used for indexing purposes.

Article structure
1. Introduction should contain scientific rationale and the aim of the study or (in the case of a review) the purpose of the article.
2. Material and methods should clearly describe the selection of observational or experimental subjects, including controls, such as age, sex, inclusion and exclusion criteria, (the circumstances for rejection from the study should be clearly defined), and the randomization and masking (blinding) methods. The protocol for data acquisition, procedures, investigated parameters, methods of measurements, and apparatus used should be described in sufficient detail to allow other scientists to reproduce the results. Name and references for the established methods should be given. References and brief description should be provided for methods that have been published but are not well known, whereas new or substantially modified methods should be described in detail. The reasons for using them should be provided, along with the evaluation of their limitations. Drugs and other chemicals should be precisely identified, including generic name, dose, and route of administration. The statistical methods should be described in detail to enable verification of the reported results. Provide information on patient informed consent. Studies on patients and volunteers require informed consent documented in the text of the manuscript. Where there is any unavoidable risk of breach of privacy (eg, in a clinical photograph or in case details), the patient's written consent to publication must be obtained and a copy provided to the journal. Information on approval by a Local Ethics Committee should also be provided.
3 Results should concisely and reasonably summarize the findings. Restrict tables and figures to the number needed to explain the argument of the paper and assess its support. Do not duplicate data in graphs and tables. Give numbers of observation and report exclusions or losses to observation such as dropouts from a clinical trial. Report treatment complications. The results should be presented in a logical sequence in the text, tables, and illustrations. Do not repeat in the text all the data from the tables or graphs. Emphasize only the important observations.
4. Discussion should deal only with new and/or important aspects of the study. Do not repeat in detail data or other material from the Background or the Results section. Include in the Discussion the implications of the findings and their limitations, including implications for future research. The discussion should address the results of other investigations, especially those quoted in the text.
5. Conclusions should be linked with the goals of the study. State new hypotheses when warranted. Include recommendations when appropriate. Unqualified statements and conclusions not completely supported by the obtained data should be avoided.
6. Acknowledgements. List all contributors who do not meet the criteria for authorship, such as technical assistants, writing assistants, or department head, who provided only general support. Financial and other material support should be disclosed and acknowledged.
