Instructions to authors


Scope and policy


The Revista Argentina de Radiología (RAR) publishes original contributions related to the field of Imaging Diagnosis and Procedures. Submissions should be written in Spanish (and, occasionally, in English).

The RAR is a journal with indexing in Index Medicus Latinoamericano (LILACS), and is included in the Latindex catalog.

Publication Criteria
The decision to accept or reject a paper is strictly based on the peer review process. The title page of manuscripts sent to referees or reviewers shall, under no circumstances, make any reference to authors and/or institutions, in order to avoid partiality.
The review process shall be as follows: the Editorial Committee makes a first appraisal of the paper that, in case of approval, is submitted to the journal appointed members of the Advisory Committee (reviewer). The latter also receives a list with all the items to be evaluated. Following this stage of the review process, the paper is submitted to the authors by the journal secretary. Once the changes (if any) suggested by the experts are made, the latter shall receive the paper again for their final approval. Should the suggested changes not be duly made, the paper is returned to the authors following the above process. Once these stages have been completed, the paper shall be either published or definitely rejected. Finally, the paper shall be evaluated by both the Editorial Committee and the proofreader.
The above instructions are in accordance with the Uniformity Requirements for Manuscripts submitted to Biomedical Journals, available at www.icmje.org.

Different types of papers:
The RAR Editorial Committee shall consider for publication those works related to General Radiology, Sonography, Computed Tomography, Magnetic Resonance Imaging, Nuclear Medicine, Procedures and specialty-related topics, such as Radiophysics. The submitted papers should be classified into one of the following types, according to their objectives:
1. Major Paper – Original Article: novel relevant information based on the statistical evaluation of own series, and arising from original researches.
The manuscript shall be arranged in sections under the following headings:
Abstract: Should be clear and informative enough to allow understanding of the paper with no need to read the whole article. It must have no more than 250 words and be structured and divided into four sections: 1) Purpose; 2) Materials and methods; 3) Results; 4) Conclusion. Three to five key words are required, and no abbreviations or references should be included.
An abstract in English should be written in all cases, whose length must be similar and its segmentation identical to the Spanish version, i.e., Purpose, Materials and methods, Results and Conclusions.
Introduction: It consists of three sections. The first one defines the problem; the second briefly describes what is already known about the problem; the third presents the manuscript objectives on the basis of the information given in the previous paragraphs.
Material and Methods: Selection criteria of the study subjects are clearly stated. These criteria include groups, age, sex, clinical signs, etc., of patients and are accurately described. The protocol (imaging technique, reading method, diagnostic or analysis criteria, reference standards, statistical tests) should be clearly explained and include useful data.
As far as non-clinical studies, all the instruments used and the subjects studied should be described clearly, to allow others to reproduce the whole study. Results should not be included in this section, and past tense verbs should be used.
Results: The manuscript results, both positive and negative, should all be presented in a clear and logic fashion. The text and tables (if any) should not repeat data. Past tense is used. Illustrations related to the analyzed/studied cases should be included in this section.
Discussion: Material and methods are discussed, and results validity is examined. In the first paragraph, authors must provide the answers to the question posed, and the reason for carrying out the study. Thus, the study results can be compared to previous knowledge and to the existing literature. Performances, limits, false diagnoses, etc., should be discussed in this section, as well as the solutions to the problem posed. Figures or illustrations should not be included in this section.
Conclusion: Summary of the study results and consequences, which should rigorously arise from the analyzed cases.
References: (See References)
2. Up Date Article, State of the Art: Update on a topic, including the latest concepts about clinical and imaging issues, and on the eventual change in diagnostic algorithms leading to the development of new techniques. Article based on the description of the author’s experience in a certain topic. Works on related topics, such as legislation, professional practice, etc., are also included in this category. An unstructured abstract should summarize the purpose and main parts. An abstract in English and key words are required.
3. Review Article: Summarizes well-established issues and includes a critical analysis of the revised literature (which should be abundant) and conclusions. Original iconography is required. Statistical meta-analysis processing should be included, if applicable.
4. Paper: Reports on a series of 3 to 8 cases associated with a condition or features of a condition about which little or nothing has been reported. Original elements on semiology, and diagnostic or therapeutic management of a condition should be provided. The material should be arranged as follows: unstructured abstract and key words (in English and Spanish), introduction, brief description of the observations, short discussion, and no need of a conclusion. Past tense for observations description. A concise literature review may be provided in the discussion. Only figures intended to illustrate the described findings (no more than 6) are encouraged. No more than 15 references should be included.
5. Pictorial Essay: Work aimed at illustrating a domain of a condition or technique through excellent-quality images. Given the didactic features of this type of work, illustrations are recommended to include arrows and/or letters properly highlighting the interest area. References and text should be rather short. It must include an unstructured abstract in English and Spanish.
6. Case Report: Report of one or two cases that, given their type of presentation, scarce frequency or unusual association with other entity, are considered rare. It must be organized in a fashion similar to that of a Paper.
7. Technical Note: Brief description of a specific or technological innovation technique or procedure, which is considered of interest to Imaging Diagnosis.
8. Opinion/Commentary: Rather short work showing the author’s judgment on a certain controversial topic. One, or at most two, authors may give his/their opinion/s, because the topic is dealt with from a personal viewpoint. No abstract is required. No more than 4 figures or tables, and no more than 5 references should be included.
9. Letters to the Editor and Reply: Criticisms of or discrepancies in articles published in the RAR, expressed in a constructive, objective and educative way. Letters must be short (500 words, approximately), and may include illustrations (up to 2). The Reply must adhere to the Letter to the Editor instructions. It should further state the article controversial issues, for the article’s author/s to answer back to the criticisms or discrepancies.                   
10. Historical Note: Short article about certain past issues that may contribute to the cultural heritage of Imaging Diagnosis.
11. Other sections: The RAR may incorporate other sections including works whose authors are specifically gathered by the Editorial Committee.

General Guidelines

Cover Letter

Manuscripts should always be submitted with a Cover Letter signed by all the authors. It should state that the work conforms to the RAR Publication Guidelines, and the category to which the work belongs.
Should some part of the manuscript (e.g. tables, illustrations) be published or submitted elsewhere, these data must be stated in the Cover Letter. Similarly, any financial relation, sponsorship or other association that may lead to a potential conflict of interest should also be stated. This statement must always be made, even when authors consider that these relations have no impact on the manuscript scientific criterion. The letter should be signed by the author and all coauthors, if any.

Patient anonymity and informed consent form

Patients have the right to privacy. Lack of an informed consent form is considered infringement of this right. The identification data should not be published in written descriptions, photographs or genealogies, except that the information is essential for scientific purposes, and the patient (or his/her parent or guardian) gives his/her written informed consent for the publication. Authors are responsible for preserving the patient’s anonymity. However, the patient’s data should never be changed or falsified to achieve anonymity. Masking patients’ eyes to avoid recognizing them in photographs is an inadequate way to preserve anonymity.
Authors should also guarantee that humans included in any and all experimental studies have given their informed consent. Moreover, authors must guarantee compliance with both the ethical guidelines from the institution they belong to, and the 1975 Declaration of Helsinki and its 2000 revision, available at http://www.wma.net/e/policy/b3.htm (English and Spanish versions).
For controlled clinical trials, authors must refer to the CONSORT (Consolidated Standards of Reporting Trials), available at http://www.consort-statement.org/.
Experimental works including animals must provide a clear explanation of animal use, as well as animal management authorization or guidelines from the state or private institution, or else statutes, either international or from the country or state where the work was performed.


Authors listed in the works submitted for publication must have made substantial contributions to them. The type of participation of each of them may be explained in the submission.
The requirements to be considered work author, or to be included as a co-author, may be found in the Uniform Requirements for Manuscripts Submitted to Biomedical Journals: Writing and Editing for Biomedical Publication (http://www.elsevier.es and http://www.icmje.org).
To be considered an author, a person must have contributed to the study conception and design, data collection, or study analysis and interpretation; or else have participated in the study writing or critical review; or have given his/her final approval to the version submitted for publication. Individuals who have participated to obtain financial support, to collect data, or supervise the team working on the study subject, should not be considered as authors. Their participation may be listed in acknowledgments at the end of the article. Should the work not meet the above criteria, the Revista Argentina de Radiología shall be entitled to publicly notify this on its pages and shall proceed to withdraw the article.


Submission of a work to the RAR for its consideration implies the following: a) that this work has not been previously published (except in the form of an abstract, or as part of a thesis); b) that this work is not being considered for publication in any other journal or scientific dissemination media (such as book, on-line journal, bulletin, etc.), and c) that its publication has been approved by all its authors/co-authors, and by the institution where it has been developed.
The authorizations from other media allowing the reproduction of previously published material should be enclosed, when applicable.

Work submission should always include the “Authorship responsibility, copyright transfer and financial disclosure” form, signed by all the authors. This form is regularly published in each RAR issue.


Form and preparation of manuscripts


Title Page
This page should include the title of the manuscript, in Spanish and English, names of authors, and address (including zip code) of the institution where the work was carried out. The corresponding author shall be identified as follows: name, address, telephone, fax and e-mail address.
An abbreviated title of the article and key words related to the article content should be included in this page.

“Blind” Title Page

Another title page providing no other data than the original title (no authors’ names, etc.) should be attached to each copy, and will be used in the peer review process.


The manuscript text should be structured according to the proper category.

Use of Abbreviations and Acronyms

Abbreviations and acronyms should be spelled out when first used in the text. The word must be followed by the abbreviation in parentheses [e.g. Helicoidal Computed Tomography (HCT)].  
The use of abbreviations in the text should be kept to a minimum, to facilitate a more fluent reading.


All articles, except for Letters to the Editor, should include an abstract. The abstract of Major Papers should be structured according to the above mentioned in these Guidelines.
As far as the other types of works, such as Pictorial Essay, Case Report, etc., there is no need for the abstract to be structured (Objective, Material and Methods, etc.).

Key words

Between 3 and 6 key words are required in all articles but Letters to the Editor. These words may be related to organs, condition, diagnostic or therapeutic method. They should be written in the title page, in Spanish and English. Look for indicators at www.nlm.nih.gov/mesh/meshhome.html.

  • References should be typed in double space, beginning on a separate page. Number references consecutively in the order in which they are first mentioned in the manuscript.  
  • Any and all citations listed as references should always be included as references in the text. These citations should be written in parentheses [e.g., (21)] at the end of the phrase containing information that requires citation. If authors’ names are to be cited, the citation shall be included immediately after these names [e.g., Greenway G. et al (4)]. References should be numbered consecutively in the order they are first cited in the text.
  • In those references where six or less authors are cited, all of them should appear, with their last name and first initial. In case of seven or more authors, only the first three should be mentioned, followed by “et al”.
  • The abbreviations used for periodicals cited in the references should follow the style of the Index Medicus/MEDLINE (available at www.nlm.nih.gov/tsd/serials/lji.html).

The use of data from other published or unpublished source requires written permission and statement of the source origin.

Figures or Illustrations
Figures or illustrations should be kept to those showing the major findings described in the text. The following numbers of figures will be allowed: a maximum of 20 figures for Major Papers, State of the Art and Review Article; up to 30 for Pictorial Essay and Historical Note; 6 for Paper and Case Report, and 2 figures for Technical Note, Opinion and Letter to the Editor. The number of each figure must coincide with that stated in the text. Figures shall be organized sequentially.
Excellent resolution, uniform size and magnification are required. JPEG or TIFF, 300 dpi (dots per inch) must be used. In case of electronically managed figures, their identification is required. Moreover, the type of modification should be stated and an original (preprocessed) image should be attached.  
Figures shall always be published in black and white. The RAR Editorial Committee shall decide about the publication of color figures, which could result in an additional cost to the authors.

The most relevant parts of the figures should be highlighted using visible signs (arrows, arrowheads, asterisks, circles, etc.) in Photoshop program.
Images containing data that allow author/institution identification are discouraged. 

Each figure must have an epigraph. All epigraphs should appear on a separate page typed in double space, as the rest of the manuscript.
Epigraphs shall include, if applicable, age, sex and diagnosis.
References in figure legends (if any) should be numbered sequentially with those in the text.
Symbols, arrows, numbers or letters (if any) used to identify different parts of the figures should all be explained at the figure footnote.

Statistic methods should be described clearly enough so that the reader skilled in the topic and with access to original data may verify the results shown.
Findings should, if possible, be quantified and showed with proper indicators of measurement error or uncertainty. Study subject eligibility should be analyzed and the randomization process should be explained.  The computing program used for the manuscript must be specified.

Acknowledgements to people for their contribution to the study or the manuscript preparation, as well as acknowledgement to centers or organizations supporting the manuscript design, may be included after the manuscript text on a separate page.



Manuscripts submission


Authors are encouraged to make their submissions online at the Revista Argentina de Radiología: http://www.rard.org.ar/ or www.rard.org.ar, through the journal link “manuscript submission”, which will facilitate the evaluation process and will diminish costs to authors. Ordinary mail can also be used.

Web submission
In the abovementioned web pages, the author will find instructions described in sufficient detail about manuscript submission, and a form to fill out his/her data and attach the paper.
The paper (in word, including content and images) should be attached to the form in compressed format (RAR or ZIP).
The author should send two files, one of them including authors’ data, institution, etc., and the other without that information. The latter shall be analyzed by the Advisory Committee.
After the manuscript revision, the author shall be informed, via e-mail, of the Committee’s decision: “Accepted”, “Not Accepted”, or “Accepted with Modifications”.
In the latter case, the author, after making the changes suggested, shall load his manuscript again (2 files .rar or .zip) following the same process. Thus, the evaluation process by the Committee shall be resumed.

The text must be written in double space (including references, tables, figure footnotes and footnote commentaries). Abbreviations or initials (if any) should be previously explained in the text.
Measurement units must be expressed in International System Units or their SI equivalent in parentheses (“Now Read This: The SI Units Are Here”, JAMA 1986;255:2329–2339).
Pages should be numbered starting by the title page.
The authors’ names should only appear on the first page.
Regarding drugs and chemical substances, their generic name, rather than their commercial name, must be used.
Digital figures
Either TIFF or JPEG format must be used for figures. As far as scanned images (x-rays, sonographies, CT, MRI, etc.), a minimal resolution of 300 dpi is required. On the other hand, illustrations must reach a minimal resolution of 1.200 dpi.
Should digital illustrations be used, their programs must be compatible with Power Point, MS Word, or Corel Draw, with the latter being saved as .AI (Adobe Illustrator).
Ordinary mail submission
Submission shall consist of two (2) printed copies of the manuscript (original and copy), including images, epigraphs and tables, which must be inserted into the text.
The manuscript shall consist of the title page (including authors’ names, affiliations, e-mail address for correspondence and key words), abstract, references, and figure and table epigraphs. The manuscript must be typed in double space, with a margin of about 2.5 cm on each side, and must be printed on only one side of the page. All pages, starting by the abstract page (excluding the title page), must be numbered consecutively. The authors’ names should not appear on the manuscript pages.
Important: A CD must also be submitted with the manuscript. A standard text processor should be used, preferably Microsoft Word. (Although conversions from other text processor software are feasible, the transformation stage may lead to random errors.) The CD shall contain title, authors, authors’ affiliation, e-mail address for correspondence, abstract in English and Spanish, key words, manuscript text, references, epigraphs and tables.
Digital images, in JPEG or TIFF format, and a resolution not lower than 300 dpi, should be sent separately. Images must not be inserted into the word document. They must be numbered as they appear in the text, using letters to identify them (e.g. 1a, 1b, etc.). Arrows or other signs (in Photoshop) must be used to highlight the findings.
