Scope and policy

The Journal Radiologia Brasileira (ISSN 1678-7099), a bimonthly publication, is the official organ of scientific dissemination of Colégio Brasileiro de Radiologia e Diagnóstico por Imagem 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. Radiologia Brasileira accepts for publication studies from Brazilian and foreign collaborators. Manuscripts forwarded to Radiologia Brasileira and accepted for publication, become a property of Colégio Brasileiro de Radiologia e Diagnóstico por Imagem. Any whole or partial reproduction of articles published in Radiologia Brasileira is forbidden without the previous consent from Colégio Brasileiro de Radiologia e Diagnóstico por Imagem.


Instructions for Authors

Note on authorship: Except for multi-institutional studies or those of outstanding complexity, the Journal considers eight (8) as the maximum acceptable number of authors for Original Articles, six (6) for Review Articles and Iconographic Essays, and five (5) for Letters to the Editor and News in Radiology.
Materials submitted for publication must be unpublished, and must not be under consideration for publication by other journals. Articles written in Portuguese must comply with the official respective orthography.

Articles will be initially reviewed by the editors regarding the minimum Radiologia Brasileira standards, and the compliance with all requirements concerning submission of original manuscripts. After that the editors will submit the article to the scrutiny of two peer reviewers, specialists in the concerned area, selected from the Editorial Board and/or from the accredited reviewers body of the Journal. The reviewers always come from institutions different from those in which the manuscripts were originated, and will not be informed about authors’ identities and institutions where the manuscript was originated. The opinions expressed in the articles, including changes originated in revision process, are sole responsibility of the authors.


Types of published articles

Radiologia Brasileira classifies the articles under the following categories, grouping them within the sections of each subspecialty:

Original Articles: New information of interest for clinical diagnosis or related to experimental or laboratory research. The manuscript shall be no longer than 3,000 words (including tables and charts, and excluding the references). The total number of tables and illustrations shall not exceed 15. In case an illustration is broken down into parts (A, B, C…), each part is to be counted as one illustration. A maximum of 30 references shall be included. The number of authors should be limited to eight (8).

Review Articles: These are articles that synthesize well established subjects, with a critical analysis of the literature reviewed and conclusions. They can be up to 4,000 words long (including tables and charts, and excluding the references), with 16 illustrations, 4 tables and 50 references. In case an illustration is broken down into parts (A, B, C…), each part is to be counted as one illustration. The number of authors should be limited to six (6).

Pictorial Essays: The primary objective is the demonstration through images of the topics presented. The text (up to 1,200 words) and the references (maximum of 10) should be summarized. Total number of illustrations should not exceed 20. In case an illustration is broken down into parts (A, B, C…), each part is to be counted as one illustration.

Ethics in Researches and Scientific Publications

RB adopts the strictest ethical standards to ensure good scientific practices. The authors are required to follow international ethical standards in their researches, from planning the study to the publication of results, as described by the Committee on Publications Ethics - COPE ( and by the World Association of Medical Journal Editors - WAME (
The following topics are relevant in relation to ethics in research: authorship, potential conflicts of interest, and academic plagiarism. The authors are asked to read it carefully before submitting articles.
Authorship: RB does not assign specific criteria for authorship. However, it suggests the authors to follow the conditions as described in the International Committee of Medical Journal Editors site - ICMJE ( and the Prof. Berquist’s (American Journal of Roentgenology’s Editor)  paper “Authorship creep: do we need a new process?” (, which were adapted in the text below. To be considered an author of the paper, the researcher must:
• Have made significant contributions in the conception and/or design of the study, acquisition, and data interpretation and/or analysis.
• Have reviewed the draft manuscript, checking it critically.
• Have contributed to the final version.
• Be responsible and accountable for all aspects of the accuracy and/or completeness of the data and/or advertised results.
Potential conflicts of interest: All authors must mention possible conflicts of interest, whether in relation to the funding of the study, besides possible financial and/or commercial interests. All procedures of the research in the ethics committee shall be made explicit. The number of approvals of the study by the appropriate ethics committee shall be provided. For prospective studies involving human subjects, the term of free and clear consent shall be mentioned, as well as the cases in which it is dismissed. In animal studies, a statement on animal welfare shall be provided. Examples of conflicts of interest are, but are not limited to:
• Research funding by funding agencies.
• Financial support by the sponsor of an event/project.
• Fees to be the speaker at an event
• Funding for educational programs.
• Consultant or position in companies directly or indirectly involved in the research project.
• Position in the advisory and/or administrative board of companies supporting the research and/or event.
• Multiple Affiliations.
• Shareholder of a company sponsoring the research/event.
Plagiarism, duplicity, and related topics: RB reserves the right to use programs to detect academic plagiarism in papers submitted to publication. We remind the authors that the various types of plagiarism are scrutinized, including, but not limited to: paraphrase without due credit to the author/authors; data citation of other researches when not mentioning its source; copies of pictures, drawings, graphics, and other visual content without permission.
The use of the same group of patients in more than one study, although for different purposes, should be reported to the editor/reviewers.
For more details on specific topics of research ethics, the magazine recommends reading/consulting the White Paper on Publication Ethics of the Council of Science Editors (
Suspected improper ethical conduct: In cases of suspected improper ethical conduct, RB will investigate the case following the guidelines of COPE under the command of the RB Editor, who may handle the case alone or may form an ad hoc committee with members of the Editorial Council. The authors will be notified by email so that they can present their claims. If the suspicion of misconduct persists, depending on the investigation, RB  may adopt one of the following measures, however, not only limited to them:
a) If the manuscript is still being evaluated, it may be rejected and returned to their authors.
b) If the manuscript has already been published, depending on the nature and severity of the event, the following measures may be taken:
b.1) An erratum/correction will be published along with the article;
b.2) An expression of concern may be inserted on the article.
b.3) In severe cases, there may be a retraction of the article.

For any doubts regarding best practices in ethical medical research, contact the Editor and/or RB Editorial Staff prior to submission.
