Publication Guidelines

Instruções aos Autores

Radiologia Brasileira (RB) (ISSN 0100-3984), which is published once every two months, is the official organ of scientific dissemination of the Colégio Brasileiro de Radiologia e Diagnóstico por Imagem (CBR, Brazilian College of Radiology and Diagnostic Imaging) and is dedicated to the publication of scientific studies of interest in the areas of radiology, nuclear medicine, ultrasonography, computed tomography, and magnetic resonance imaging.

The RB accepts manuscripts written in Portuguese or English. Articles submitted in Portuguese are translated to and published in English. Materials submitted for publication must be unpublished and must not be under consideration for publication elsewhere. Manuscripts submitted to RB and accepted for publication become the property of the CBR. Any whole or partial reproduction of articles published in RB is forbidden without prior consent from the CBR.

Submitted articles will initially be reviewed by the RB editors, who will verify that the manuscripts meet the minimum standards of the Journal and are in compliance with all requirements concerning submission of original manuscripts. The editors will then submit the article to the scrutiny of two peer reviewers who are specialists in the area of interest, selected from the editorial board or from the list of accredited RB reviewers. The editors always select reviewers from institutions different than those from which the manuscripts originated, and the reviewers are blinded to the identities of the authors and the institutions of origin. The opinions expressed in the articles, even after revisions requested by the editors, are the sole responsibility of the authors.

Note on authorship: Except for multicenter studies or those of outstanding complexity, the Journal imposes a maximum acceptable number of authors for each article type: eight for original articles; six for review articles and pictorial essays; and five for letters to the editor and advances in radiology articles.

Types of articles

The RB classifies the articles according to the specifications described below.

Original Articles:Original articles should contain new information of interest for clinical diagnosis or related to experimental or laboratory research. The manuscript should contain no more than 3,000 words (including tables and figure legends; excluding the title page, abstract, and references). The total number of illustrations (tables and figures) should not exceed 15. If a figure is divided into panels (A, B, C, etc.), each panel will be counted as one illustration. The number of references should not exceed 30. The number of authors should be limited to eight.

Review Articles: Review articles are submitted, at the invitation of the editors, by specialists in the field. These articles should synthesize information on well-established subjects, with a critical analysis of the literature reviewed and conclusions. They can contain up to 4,000 words (including tables and figure legends; excluding the title page, abstract, and references), with a maximum of 16 figures, 4 tables, and 50 references. If a figure is divided into panels (A, B, C, etc.), each panel will be counted as one illustration. The number of authors should be limited to six.

Pictorial Essays: Pictorial essays are submitted, at the invitation of the editors, by specialists in the field. Their primary objective is the demonstration of the topics presented, through the use of illustrations. The text should not exceed 1,200 words (excluding the title page, and abstract), the number of references should not exceed 10, and the number of illustrations should not exceed 20. If a figure is divided into panels (A, B, C, etc.), each panel will be counted as one illustration. The number of authors should be limited to six.

Case Reports: As of December 1, 2014, case reports will no longer be accepted for publication in the Journal.

Letters to the Editor: Letters to the editor should consist of constructive, objective, respectful criticism on published articles or disquisition on diagnostic situations. Discussions on radiology-specific topics are published at the discretion of the editors. Such letters should be concise, not exceeding 500 words. The number of authors should be limited to five.

Note: Due to the large backlog of letters to the editor awaiting publication, the submission of clinical case reports as letters to the editor has been suspended, until further notice, as of November 15, 2017. Letters commenting on articles published in the Journal will continue to be received and evaluated.

Editorial: Editorials can be written by any professional at the request of the editor. Editorials dealing with subjects of a political nature must be approved by the editorial board.

Advances in Radiology: Advances in radiology articles consist of a brief description of a specific technique or procedure, modification of a technique, or new equipment of interest to radiologists. They should not contain more than 500 words, 8 references, and 4 illustrations. The number of authors should be limited to five.


The recommendations below are based on the for the Conduct, Reporting, Editing and Publication of Scholarly Work in Medical Journals. Even when prepared and written in accordance with those recommendations, manuscripts will be edited to conform to the in-house style of the Journal

The corresponding author must be clearly identified. A complete mailing address, email address, and telephone number for the corresponding author must be included. A short running head of no more than 60 characters (including letters and spaces) should also be included.

Abstract and Keywords

Structured abstracts (in Portuguese and English) with a maximum of 200 words must be included in each Original Article manuscript. Abstracts must contain the following items: Objective: Describe the tested hypothesis or evaluated procedure Materials and Methods:Briefly describe what was done and the materials used, including the number of patients, the methods used to evaluate the data and to avoid bias. Results: Please cite the findings of the study, including indicators of statistical significance. Actual numbers and percentages must be included. Conclusion: The conclusion(s) based on the findings should be summarized in one or two sentences. Uniterms: Three to six Uniterms and respective keywords should be listed below the abstracts, preferably according to the Health Sciences Descriptors (DeCS) or the of the National Library of Medicine.

For Review Articles and Iconographic Essays, abstracts of 100 to 200 words should summarize the content of the article, which should not be divided into items. List three to six uniterms/keywords. References should not be cited in abstracts.


Original articles should be divided into the following sections: Introduction, Materials and Methods, Results, and Discussion. If appropriate, a Conclusion section may be included after the Discussion.

Introduction: The Introduction section should provide an explanation of the relevance of the investigation and a brief description of its objectives.

Materials and Methods: The Materials and Methods section should provide a description of the study design, the materials (or patients) involved, and the methods adopted, in that order. If relevant, a detailed explanation on how the diagnosis was confirmed should be included, as well as explanations on how the subjectivity of the observations was controlled. In order to ensure anonymity in the peer review process, neither the name of the institution where the study was developed nor the names of the authors should not be mentioned.

Results: The results are to be presented in a clear, logical sequence. If tables are included, tabular data should not be duplicated in the text, which should instead highlight the significant findings and trends.

Discussion: When the results differ from those obtained in previous studies, the discrepancy should be explained. The limitations of the study design, materials (or patient sample), and methods should be described in view of the objectives and results of the study.

Conclusion(s): When appropriate, the conclusions are to be described in summarized sentences.

Acknowledgments: Individuals or institutions who have made contributions that do not merit authorship should be mentioned in the Acknowledgments section, as should any relevant financial or technical support received.

Note:: A complete list of examples of bibliographic citations can be found at

References to abstracts, editorials and letters should be identified as such. Unpublished data and personal communications should not be included in the reference list but may be mentioned parenthetically in the text, for example, as "(Smith DJ, personal communication)", "(Brown AC, unpublished data)", etc., as may articles submitted but not yet accepted for publication.

The accuracy of the references is the responsibility of the authors.


Each table should be typed double-spaced, in 11-point font, without vertical or horizontal rules. Each table must have a brief descriptive title, should not occupy more than one page, and should comprise at least four lines and two columns of data. Tables should be numbered with Arabic numerals, in the order of their citation in the text. Definitions of abbreviations and footnotes must be included in the table footer, rather than in the title. Footnotes should be indicated with superscript lower-case letters. Tables should be self-explanatory and should not duplicate data presented in the text or in other illustrations. The accuracy of all arithmetic calculations (percentages, totals, and differences) should be checked, and tabular data must match data mentioned in the text.

Figures and Legends

Each figure should be entered into the system separately. Each figure must have a legend, and it is essential that the legend describes all characteristics of the figure. The scope of a figure should be limited to that necessary to illustrate the essential characteristics described in the manuscript. Preferably, each illustration should depict only the area(s) of interest, with enough surrounding visual context to allow proper orientation. It is mandatory to indicate all characteristics described in the legends, using different indicators for each (the use of equilateral triangles as arrows should be avoided). The indicators are to be directly applied on the figure, clearly indicating the lesions (or structures) that one wishes to evidence. If a figure is divided into panels (A, B, C, etc.), each panel will be counted as one illustration. Photographic images must be submitted as .jpg, .gif, or .tiff files, with a 300-dpi resolution for an approximate size of 9 × 12 cm.

Units and Abbreviations

Radiation measurements and laboratory values are to be based on units of the International System of Units in Radiation Protection and Measurements, NCRP Report. 28, August 1985.

If possible, the use of abbreviations or acronyms should be avoided in the main title of the article and in the abstract. Abbreviations should be defined at their first mention in the text - e.g., "computed tomography (CT)" - after which the term in full should not appear again.

Clinical trial registration: Since August 2007, all periodicals indexed in the Literatura Latinoamericana y del Caribe en Ciencias de la Salud (Latin-American and Caribbean Health Sciences Literature) and Scientific Electronic Library Online databases require that randomized controlled trials and clinical trials submitted for publication be previously registered in a clinical trials database. That decision was based on the recommendation from the from the ICMJE. Instructions for registration are available at the ICMJE website, and trials can be registered via the

Plagiarism, duplicate publication, and related topics: RB reserves the right to use plagiarism detection programs to evaluate manuscripts submitted for publication. We remind authors that the various types of plagiarism are scrutinized: paraphrasing without giving proper credit to the original author(s); citing data from another study without mentioning the source; and using copies of images, drawings, graphics, or other visual content without the permission of the copyright holder. If the same group of patients is used in more than one study, even for different purposes, the authors should inform the editor/reviewers of that. For additional details on specific topics related to ethics in research, the Journal recommends consulting the Council of Science Editors do Council of Science Editors.

Cases of suspected breaches of ethical conduct: In cases of a suspected breach of ethical conduct, RB will conduct an investigation following the COPE guidelines, under the direction of the RB Editor-in-Chief, who may investigate the case personally or form an ad hoc committee comprising members of the Editorial Board. Authors will be notified by email so that they can reply to the allegations. If the suspicion of misconduct persists, depending on the results of the investigation, the Journal may take measures including, but not limited to, the following:

a) If the manuscript is still under evaluation, it may be rejected and returned to its authors.

    b) If the manuscript has already been published, depending on the nature and seriousness of the misconduct, one or more of the following measures may be taken:
  • 1) An erratum/correction may be placed with the article.
  • 2) An expression of concern may be inserted into the article.
  • 3) In the most severe cases, the article may be retracted.

Any questions regarding best ethical practices in medical research should be directed to the editor or staff of the RB prior to submission.
