Scope and policy

The Journal Radiologia Brasileira (ISSN 0100-3984), a bimonthly publication, is the official organ of scientific dissemination of Colégio Brasileiro de Radiologia e Diagnóstico por Imagem (CBR) and is dedicated to the publication of scientific studies of interest in the areas of Radiology, Nuclear Medicine, Ultrasonography, Computed Tomography, Magnetic Resonance Imaging and Radiation Physics and Biology. Radiologia Brasileira accepts for publication studies from Brazilian and foreign collaborators. Manuscripts forwarded to Radiologia Brasileira and accepted for publication, become a property of CBR. Any whole or partial reproduction of articles published in Radiologia Brasileira is forbidden without the previous consent from CBR.


Instructions for Authors

Note on authorship: Except for multicentre 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 Pictorial Essays, five (5) for Letters to the Editor, and two (2) for the remaining categories. In the case of a higher number of authors, a letter describing the participation of each author in the study should be submitted to the Editorial Secretariat.

Materials submitted for publication must be unpublished, and must not be under consideration for publication by other journals.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 orthography. When originated from foreign institutions, they may be published in English, as submitted.

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 made by the editors, 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 8. 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.

Review Articles: Requested by the Editors from specialists in the field. 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 12 illustrations, 4 tables and 50 references.

Pictorial Essays: Requested by Editors from specialists in the field. Their 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.

Case Reports: As from December 1st, 2014, case reports will not be accepted anymore for publication in the journal Radiologia Brasileira.

Letters to the Editor: Constructive, objective and polite criticism on published articles, inquiries about diagnostic situations. Discussions on radiology-specific topics shall be published at the Editors' discretion. Such letters should be concise, not exceeding 500 words. Like Letters to the Editor, a brief discussion of clinical cases with unusual imaging features of interest for the scientific community might be submitted. It should not exceed 500 words, 8 references, and a maximum of 4 images (preferably presented as a single figure).

Editorial: Can be written by the Editors or by any other member of CBR. Subjects of political matter should be approved by the Editorial Board.

For News in Radiology, abstracts of 60 words or less should be submitted with each article. Such information is not to be broken down into items.

References corresponding to abstracts, editorials and letters shall be registered as such. It is the author's responsibility that all references are precisely listed.

Unpublished data and personal communications should not be included in the references list, but may be mentioned on the text in parenthesis: (Smith DJ, personal communication), (Brown AC, unpublished data). These data include articles submitted but not yet accepted for publication.

e) Tables

Each table should be typed in double space, and 11 point font, without vertical or horizontal lines. Each table must have a brief descriptive title. They should not be more than one page long, and should present at least four lines and two columns of data. Tables should be numbered in Arabic numerals, in the same order as mentioned in the text.

Each illustration shall be separately entered into the system. All illustrations must have a legend, and it is essential that such legend describes all characteristics of the illustration. Illustrations should be limited to the needs of showing 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 pointers for each one of them (equilateral triangles shall be avoided as arrows). The pointers are to be directly applied on the figure, touching the lesions (or structures) that one wishes to evidence. In the case of more than one illustration belonging to the same case, they should be grouped over a single legend, and each one should be identified with letters (A, B, C, etc.).

Color illustrations will only be so published in case the Editors conclude that the colors are necessary to properly convey the information on the illustration. Photographic images must be submitted as jpg, gif or tif files, with a 300 dpi resolution for an approximate size of 9 x 12 cm.

g) 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.

Abbreviations or acronyms must be avoided. They should never be utilized in the manuscript title, and also, preferably, never in the abstract. When utilized in the text, they should be totally described when first mentioned, followed by the abbreviation or acronym in parenthesis.

Committee for Ethics in Research: Studies reporting results with humans shall be supported by the appropriate authorization from the Committee for Ethics in Research of the institution where the study was developed.

Clinical trials registration: Since August of 2007, all the periodicals indexed in the Lilacs and SciELO databases require the randomized controlled trials and clinical trials submitted for publication to be registered in a Clinical Trials database. Such decision is based on the orientation from the International Clinical Trial Registry Platform (ICTRP) of the World Health Organization (WHO), and from the International Committee of Medical Journal Editors (ICMJE). Instructions for registration are available at the ICMJE website ( and the registration can be made on the Clinical Trial database of the National Library of Medicine available at
