AJDRAJNR - American Journal of Neuroradiology

Information for Authors

The American Journal of Neuroradiology (AJNR) publishes original articles pertaining to the clinical imaging, therapy, and basic science of the central and peripheral nervous system, including but not limited to the brain, spine, head and neck, interventional procedures, techniques in imaging and intervention, and related educational, socioeconomic, and medicolegal issues. The content of the AJNR is determined by the Editors.

Types of articles the AJNR will consider for publication include Original Research, Case Reports, Technical Notes, Letters to the Editor, and special papers including Review Articles and radiologic-pathologic correlations. Other items such as Book Reviews are solicited and approved by the Editors as well. Please note that Letters and Book Reviews will now be published online only. Please note that manuscripts presenting research supported by any government funding source from any nation will be published in an open access manner with no restriction of content from initial on-line posting.

Submitted manuscripts must not contain previously published material or material under consideration for publication elsewhere unless specific permission is obtained. Accepted manuscripts become the property of the AJNR and may not be republished without its consent.

Manuscripts will undergo peer review, and an AJNR Editor will then make a decision relative to publication.

The AJNR encourages and will give particular attention to investigations that are prospective in nature and in which specific hypotheses are proposed.

Author Responsibilities

By submitting a manuscript for publication, each author acknowledges having made a substantial contribution to the concept and design of the study, the analysis and interpretation of the results, and the writing of the paper in addition to having approved the final submitted version. Each author thus acknowledges responsibility for the integrity of the manuscript, assures the originality of the paper, and guarantees that duplicate or redundant publications/submissions have not occurred. If the submitted manuscript builds on previously published articles, authors are encouraged to enclose copies of those articles with the new submission. The Editors reserve the right to request the original data obtained in the investigation.

Conflicts of interest and/or disclosure statements, if applicable, must be included with all submissions using the appropriate form (click here to download). Disclosure is not intended to prevent authors with potential conflicts of interest from contributing to the AJNR; rather it places on record any relationship that may exist with mentioned or competing products or firms. Disclosed information will be held in confidence during the review process and the Editors will determine the nature of any printed disclosure accompanying a published article. Authors are responsible for notifying the Journal of financial arrangements including, but not limited to, agreements for research support (including provision of equipment or materials), speaker bureaus, consulting, or ownership interests. It is important that disclosure statements be updated promptly to reflect any new relationships that arise after the initial submission of the manuscript. Authors should upload PDF versions of the signed disclosure statements in Manuscript Central using the space designated for cover letters and use the following format for filenames: [Author Last Name] Disclosure [Last 4 Digits of Manuscript Number].

When a large, multi-center group has conducted a study, the group should identify the individuals who accept direct responsibility for the manuscript. At least one person’s name must accompany a group name (e.g., H.J. Cloft, for the HEAL Investigators). These individuals should fully meet the criteria for authorship defined above. When submitting a group author manuscript, the corresponding author should clearly indicate the preferred citation and identify all individual authors as well as the group name. The AJNR will generally list other members of the group in the acknowledgments. Groups of persons who have contributed materially to the paper but whose contributions do not justify authorship may be listed under a heading such as "Clinical Investigators" and their function or contribution should be described (e.g., "served as scientific advisors," "collected data," or "provided and cared for study patients"). The National Library of Medicine indexes the group name and the names of individuals the group has identified as being directly responsible for the manuscript.

All authors should read the following instructions before submitting a manuscript to assure timely handling and review of their material. Authors should strive to present their manuscripts in a clear and logical manner. Authors are responsible for all statements made in the text.

We strongly encourage authors for whom English is not their native language to seek assistance from a colleague experienced in medical terminology and translation to ensure that the words used both accurately and clearly convey the intended meaning. Failure to do so may compromise the review of your manuscript.

These instructions are based in part on recommendations as set forth in the International Committee of Medical Journal Editors' Uniform Requirements for Manuscripts Submitted to Biomedical Journals and the AMA Manual of Style. Authors are encouraged to consult both of these publications, which contain helpful details on the construction and writing of scientific manuscripts. Variations from guidelines in those publications reflect the individual style of the AJNR.

Duplicate/Redundant Publication

The Council of Science Editors defines redundant publication as "reporting (publishing or attempting to publish) substantially the same work more than once, without attribution of the original source(s)" (CBE Views 1996;19 (4):76-77). Characteristics of reports that are substantially similar include (a) "at least one of the authors must be common to all reports; (b) "the subject or study populations are often the same or similar"; (c) "the methodology is typically identical or nearly so"; and (d) "the results and their interpretation generally vary little, if at all."

Should any member of the Editorial Board of AJNR become aware of the possibility of redundant/duplicate publication, the Editor-in-Chief will:

  1. If the article is still in the process of peer review, suspend it until final determination is made. A determination of redundant/duplicate publication will result in immediate rejection of the article and notification of the Editor(s) of other journals involved.
  2. If the article(s) in question has already been published by AJNR:
    1. Compare and study both publications to determine their content.
    2. Ask one or more Senior Editors and/or a member(s) of the Editorial Board to determine if the article in question falls into the category of redundant/duplicate publication.
    3. If the article is considered as redundant/duplicate, retract it from publication in AJNR and PubMed and notify the author(s).
    4. Publish a notification of the retraction in AJNR and give authors(s) involved the opportunity to respond.
    5. Further sanctions to be considered by the Editor-in-Chief and Senior Editors on an individual basis include:
      1. A flexible time ban for material by any of the authors.
      2. Notification of the authors’ department chairs and other authorities of their respective universities.
    6. If redundancy, duplication, or plagiarism occurs in an article(s) arising from research funded by a government means, the Office of Research Integrity from Department of Health and Human Services will be notified.

Categories of Submission

ORIGINAL RESEARCH
Original Research Word Limits:

    Abstract—250 words
    Text, including references and tables—6100 words
    Figures—The average one-column image plus legend equals 100 words; space taken up by figures must be subtracted from the text word count.

      TITLE PAGE.—The following information should appear: title of article; first name, middle initial, and last name of author(s); affiliations, grant support, and presentation in part or whole at any meeting. Identify the corresponding author and provide full mailing address, phone and FAX numbers, and e-mail address. Authors may indicate level of contribution to the paper and this will be reflected in the final published article. The number of authors should be limited to 8 for Original Research and 4 for Technical Notes and Case Reports. Justification for the inclusion of additional authors may be proposed through a written explanation of the nature of the contribution of each author.

      ABSTRACT.—The abstract is limited to 250 words and should describe the essential aspects of the investigation in four subheadings: Background and Purpose (in the first sentence, state the background information/rationale for the investigation; in the second sentence, state your specific purpose or hypothesis), Materials and Methods, Results (summarize actual data), and Conclusion (brief statement directed to the stated purpose or hypothesis). No references should be cited.

      INTRODUCTION.—Please write a brief introduction to the paper that outlines the Background/Purpose in further detail.

      METHODS.—This section may be divided into subsections if it facilitates reading the paper. The research design, patients/subjects, material used, means of confirming diagnoses, and statistical methods should be included. Papers with statistical analysis should be prepared in consultation or coauthorship with someone who has statistical expertise. Do not mix results and discussion into this section. Do not include manufacturer’s names unless the specific product is important to the procedures performed, in which case, the city and state or country of the manufacturer should also be given. Indicate that informed consent has been obtained from patients who participated in clinical investigations. In animal experimentation, acknowledge that National Institutes of Health or equivalent guidelines were followed. When appropriate, indicate that approval was obtained from the institution’s review board. If there is a sponsoring company, include at the end of this section what input that company had in the formulation of the paper.

      RESULTS.—This section may be divided into subsections if it facilitates reading the paper. Present results in a clear, orderly fashion, and include statistical findings to substantiate the results. All results based on methods must be included. If tables and graphic material will ease the understanding of the results, include them. However, when the results can be summarized easily in a narrative form, do not use tables. Cite figures to illustrate findings.

      DISCUSSION.—Start with limited, pertinent background information and then discuss the results of the investigation in light of what has been published in the past, the limitations of your study, the implications for patient care, and potential directions for future research. Where appropriate, cite figures and graphs.

      CONCLUSION.—In a separate section, summarize the major findings of the study and their clinical usefulness (if applicable). This paragraph should address the hypothesis or purpose stated earlier in the paper.

      ACKNOWLEDGMENTS.—Obtaining permission to include a name in this section from the acknowledged individual is advised.

      REFERENCES.—Provide only the references that give essential background material. SEE ALSO: References section.

    REVIEW ARTICLES

    Authors are encouraged to contact the Editor-in-Chief (Castillo{at}med.unc.edu) before preparing an unsolicited Review Article to avoid duplication of other work already in progress.

    Review Article Word Limits:

      Abstract—150 words
      Text, including references and tables—6100 words
      Figures—The average one-column image plus legend equals 100 words; space taken up by figures must be subtracted from the text word count.

        TITLE PAGE.—SEE: Original Research/Title Page.

        ABSTRACT.—The abstract should be a one paragraph summary of the article.

        TEXT.—After a brief introduction, this section may be divided into subsections to facilitate reading the paper. Discuss pertinent background information, review the major findings of articles published in the past and the limitations of these studies, the implications for patient care, and potential directions for future research.

        TABLES AND FIGURES.—If tables and graphic material will ease the understanding of the results, include them. However, when the results can be summarized easily in a narrative form, do not use tables. Cite figures to illustrate findings. Five illustrations and one table are generally sufficient to supplement the text of a Review Article.

        REFERENCES.—Provide only the references that give essential background material. Review Articles generally contain an average of 65 references. SEE ALSO: References section.

        ACKNOWLEDGMENTS.—Obtaining permission to include a name in this section from the acknowledged individual is advised.

    CASE REPORTS/TECHNICAL NOTES
    While the AJNR encourages the submission of full-length Original Research papers, it will consider the publication of a limited number of concise Case Reports and Technical Notes. These should be unusually educational and medically important.

      Abstract—75 words
      Text, including references and tables—1650 words
      Figures—The average one-column image plus legend equals 100 words; space taken up by figures must be subtracted from the text word count.

    • All text is to be double-spaced with sufficient margins, and all pages are to be numbered.
    • Type size should be at least 12 points.
    • Do not justify the margins.
    • Preserve anonymity by ensuring that the authors’ names appear only on the title page (which should be a separate electronic file) and by eliminating references to institutions, affiliations, and previous work by the authors (stated as such in the manuscript).
    • Organize the manuscript as follows: title page (separate file), blind title page (title only), abstract, introduction, methods, results, discussion, conclusion, acknowledgments, references, tables, and figure legends.
    • Keep acronyms to a minimum. When an abbreviation is used, define it at first mention and follow with the abbreviation in parantheses.
    • For revisions, please include a cover letter detailing all changes that were made to the manuscript. You will be prompted for this letter by Manuscript Central upon submitting your revision.

    FIGURES AND LEGENDS

    • The AJNR uses electronic images for reproduction. Submit all figures in JPG, TIF, or EPS format. Glossy prints are no longer required.
    • Do not include authors’ names in the filename or in the image file itself.
    • Each image should be a separate file with the figure number indicated in the filename.
    • To ensure the best possible reproduction quality of electronic images, please follow the guidelines at http://cjs.cadmus.com/da/ when creating images.
    • Legends should be in present tense (eg, ‘T1-weighted MR image shows…’).
    • Images should not be redundant. Excessive illustrative material is to be avoided.
    • Images should be uniform in size and magnification.
    • Sagittal projections or lateral images are to be submitted with the patient facing the reader’s left.
    • Illustrations should not have marks, circles, or numbers in the area around the image and should be free of all identifying information relative to the patient and institution.
    • Line drawings should be professional in quality, done in black on a white background.
    • Written permission for use of all previously published illustrations must be included with submission, and the source should be referenced in the legends.
    • Written permission from any person recognizable in a photo is required.
    • Legends must be double-spaced, and figures are numbered in the order cited in the text.
    • Label all pertinent findings.
      RESOLUTION REQUIREMENTS FOR JPG/TIF/EPS FILES:
        Line Art (black and white).—1200 DPI/PPI
        Halftones.—300 DPI/PPI

Members of ASNR will be charged $275 per manuscript and non-member authors will pay $325. If you do not wish to have images reproduced in color, please gray-scale the files before submission.

      ELECTRONIC MODIFICATION/MANIPULATION OF IMAGE FILES:
      The following global changes to improve the quality of illustrations or remove identifying information are acceptable:
      • changing image size and resolution as detailed above
      • globally adjusting contrast and brightness (as long as no parts of an image are completely masked by them)
      • blocking or erasing patient/institutional/manufacturer identifiers
      • minimally "cleaning" unwanted noise in the background
      • aligning an image that is tilted
      • cropping unnecessary surrounding black space
      All cloning, whether done to delete or enhance a part or parts of an image is viewed as suspicious. No specific feature within an image may be enhanced, obscured, moved, removed, or introduced. Should such alterations be suspected, the images will be sent to our printer for digital analysis. We may then contact the corresponding author and ask for the original unaltered image files. Any manipulation of an image must be explained in the accompanying legend.

    TABLES

    • Each table is double-spaced and begins on a separate page without vertical or horizontal rules.
    • Type size is not reduced (tables may span more than one page).
