    3. General information

    3.1 Authorship

    Acta Radiologica follows the authorship guidelines of the ICMJE ( and does not allow more than 7 authors. Manuscripts with more than 7 authors must provide for the editor specific information on how each author has significantly contributed to the development of the manuscript. Authorship should be based on the following criteria:

    •Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; AND

    •Drafting the work or revising it critically for important intellectual content; AND

    •Final approval of the version to be published; AND

    •Agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

    This information must for each author be given in the cover letter and on the title page following the manuscript. Following these instructions does not automatically guarantee listing of all names as authors as the given contribution from each person will be evaluated individually in concordance with internationally accepted regulations of authorships.

    Authors should meet the conditions of all of the points above. Each author should have participated sufficiently in the work to take public responsibility for appropriate portions of the content.
    When a large, multicenter group has conducted the work, the group should identify the individuals who accept direct responsibility for the manuscript. These individuals should fully meet the criteria for authorship.

    Acquisition of funding, collection of data, or general supervision of the research group alone does not constitute authorship, although all contributors who do not meet the criteria for authorship should be listed in the Acknowledgments section.

    Please refer to the ICMJE Authorship guidelines at

    3.2 Research ethics

    All papers reporting animal and human studies must include whether written consent was obtained from the local Ethics Committee or Institutional Review Board. Please ensure that you have provided the full name and institution of the review committee and an Ethics Committee reference number.

    We accept manuscripts that report human and/or animal studies for publication only if it is made clear that investigations were carried out to a high ethical standard. Studies in humans which might be interpreted as experimental (e.g. controlled trials) should conform to the Declaration of Helsinki and typescripts must include a statement that the research protocol was approved by the appropriate ethical committee. In line with the Declaration of Helsinki 1975, revised Hong Kong 1989, we encourage authors to register their clinical trials (at or other suitable databases identified by the ICMJE, If your trial has been registered, please state this on the Title Page. When reporting experiments on animals, indicate on the Title Page which guideline/law on the care and use of laboratory animals was followed.

    3.3 Patient consent

    Authors are required to ensure the following guidelines are followed, as recommended by the International Committee of Medical Journal Editors, Uniform Requirements for Manuscripts Submitted to Biomedical Journals. Patients have a right to privacy that should not be infringed without informed consent. Identifying information, including patients' names, initials, or hospital numbers, should not be published in written descriptions, photographs, PACS images or pedigrees unless the information is essential for scientific purposes and the patient (or parent or guardian) gives written informed consent for publication. Informed consent for this purpose requires that a patient who is identifiable be shown the manuscript to be published.

    Identifying details should be omitted if they are not essential. Complete anonymity is difficult to achieve, however, and informed consent should be obtained if there is any doubt. For example, masking the eye region in photographs of patients is inadequate protection of anonymity. If identifying characteristics are altered to protect anonymity, such as in genetic pedigrees, authors should provide assurance that alterations do not distort scientific meaning and editors should so note. When informed consent has been obtained it should be indicated in the submitted article.

    3.4 Statistical analysis

    Where statistical analyses have been carried out please ensure that the methodology has been accurately described. In comparative studies power calculations are usually required. In research papers requiring complex statistics the advice of an expert statistician should be sought at the design/implementation stage of the study.

    3.5 Randomized controlled trials

    All randomized controlled trials submitted for publication in Acta Radiologica should include a completed Consolidated Standards of Reporting Trials (CONSORT) flow chart. Please refer to the CONSORT statement website at for more information.

    3.6 Permissions

    Authors are responsible for obtaining permission from copyright holders for reproducing any illustrations, tables, figures or lengthy quotations previously published elsewhere.

    Title page
    Title page, including manuscript title, author(s)'s names and surnames, affiliation(s), corresponding author's name, address, fax and e-mail; must be uploaded as a separate file on Manuscript Central to allow double-blind peer-review. To secure a blinded review, the acknowledgement, conflict of interest and funding should be given on the title page, and not in the manuscript itself. Such information will be included in the manuscript when the article has been accepted. Provide a blind title page with title only as the first page of the manuscript. The manuscript itself has to be cleared of any information that unveils the identity of the authors and their institution to allow double-blind peer-review.

    The Abstract must under no circumstances exceed 250 words and must be organized in the following subsections:
    Background of the article (max 2 medium-length sentences)
    Purpose (should always start as: “To…” and consist of one sentence only)
    Material and Methods
    Key words (Up to six key words should be provided. Use the drop-down menu in Manuscript Central)
    Review articles should have a non-structured Abstract which should be limited to 100 words. Short reports should have an Abstract structured like an original article. The number of words must not exceed 150 words.

    Main body
    The Abstract and main body together should as a rule not exceed 3000 words. The main body of an original article and a short report should be organized in the following sections:
    Material and Methods
    Discussion, with the conclusion as a last paragraph starting with "In conclusion, ..."

    Any acknowledgements should appear first at the end of your article prior to your Declaration of Conflicting Interests (if applicable), any notes and your References. All contributors who do not meet the criteria for authorship should be listed in ‘Acknowledgements’ section. Examples of those who might be acknowledged include a person who provided purely technical help, writing assistance, or a department chair who provided only general support. Authors should disclose whether they had any writing assistance and identify the entity that paid for this assistance.

    Conflict of interest 
    Within your Journal Contributor’s Publishing Agreement you will be required to make a certification with respect to a declaration of conflicting interests. It is the policy of Acta Radiologica to require a declaration of conflicting interests from all authors enabling a statement to be carried within the paginated pages of all published articles.

    Please include any declaration at the end of your manuscript after any acknowledgements prior                to the references, under a heading ‘Declaration of Conflicting Interests’. If no declaration is made the following will be printed under this heading in your article: ‘None Declared’. Alternatively, you may wish to state that ‘The Author(s) declare(s) that there is no conflict of interest’.

    When making a declaration the disclosure information must be specific and include any financial relationship that all authors of the article has with any sponsoring organization and the for-profit interests the organization represents, and with any for-profit product discussed or implied in the text of the article.

    Any commercial or financial involvements that might represent an appearance of a conflict of interest need to be additionally disclosed in the covering letter accompanying your article to assist the Editor in evaluating whether sufficient disclosure has been made within the Declaration of Conflicting Interests provided in the article.
