Guidelines for Authors

Authors must submit all manuscripts using the online submission and peer review system at http://ajr.edmgr.com.

Submission and peer review questions should be addressed to: AJRsubmit@arrs.org

 

GENERAL INFORMATION

The AJR publishes high-quality clinically oriented articles in all radiology subspecialties. The journal publishes a variety of article types, including original research, reviews, and editorials. Studies should be performed using human subjects and be relevant to the clinical practice of radiology.

Submitted articles will first be assessed by Editorial Board members. The editorial board may render a final decision based on its evaluation of the submission or choose to send the paper for external peer-review using a double-blind review process. Submissions will be evaluated with respect to the novelty, scientific rigor, reader interest, and importance in the field. External reviewers will be provided a 10-day window to complete their review to facilitate a rapid decision. A comprehensive technical check to ensure compliance with journal guidelines will be performed when a revision is requested from the authors. The Editor-in-Chief will issue the final acceptance for all articles.

Original Research

Hypothesis-based investigation that attempts to provide strong evidence as to the validity of the hypothesis. The manuscript is organized into the following four major sections: Introduction, Methods, Results, and Discussion. Authors are also referred to the AJR Author Guide for Original Research. for further guidance regarding this article type.

Highlights: Organized into the following two sections: Key Finding (maximum 50-word summary of the study’s most important result, expressed using concrete data) and Importance (maximum 25-word summary of the importance of the Key Finding).

Abstract: Maximum 350 words, organized into the following six sections: Background, Objective, Methods, Results, Conclusion, and Clinical Impact.

Maximums: 4500 words (Introduction through Discussion); 50 References (100 for articles in Evidence Synthesis and Decision Analysis section); 5 Tables; 7 Figures (15 total Figure parts)

Supplemental Data allowed for necessary tables and figures beyond the maximums to be included in the primary article (see below regarding submission guidelines).

 

Systematic Review/Meta-Analysis

Investigation of a defined clinical question based on a selection and synthesis of the available evidence, possibly with a statistical summary to aid the data synthesis. Articles should follow the PRISMA-Diagnostic Test Accuracy reporting guidelines, ensuring that the expected reporting items are included in each section of the Abstract and main text. The manuscript is organized into the following four major sections: Introduction, Evidence Acquisition, Evidence Synthesis, and Discussion.

Highlights: Organized into the following two sections: Key Finding (maximum 50-word summary of the study’s most important result, expressed using concrete data) and Importance (maximum 25-word summary of the importance of the provided key finding).

Abstract: Maximum 350 words, organized into the following six sections: Background, Evidence Acquisition, Evidence Synthesis, Conclusion, and Clinical Impact.

Maximums: 4500 words (Introduction through Discussion); 100 References; 5 Tables; 7 Figures (15 total Figure parts)

Supplemental Data allowed for necessary tables and figures beyond the limits to be included in the primary article (see below regarding submission guidelines).

 

Review

Scholarly analysis of recent developments on a specific topic as reported in the literature. No new data are presented. Articles presenting personal experiences or opinions should be submitted as a Clinical Perspective or Opinion articles, respectively.

Highlights: Three bulleted key points (maximum 25 words per point) reflecting the article’s key messages.

Abstract: Maximum 200 words, unstructured.

Maximums: 4500 words; 100 References; 5 Tables, 12 Figures (30 total Figure parts).

 

Best Practices

Review of the available evidence for an important clinical question that seeks to provide practice guidance. In comparison with traditional reviews, these articles (1) are more narrowly focused on a specific question (e.g. “what is the best imaging technique to evaluate right lower quadrant pain in a pregnant patient”) and (2) have a strong emphasis on evidence evaluation. Authors heavily probe, summarize, and synthesize the available evidence and may incorporate a formal meta-analysis. Critically, authors are asked to provide guidance in the absence of perfect information and to highlight gaps in evidence that call for additional research. The manuscript is organized into the following seven sections: (1) Clinical Vignette and Image(s), (2) The Imaging Question, (3) Background/Importance, (4) Synopsis and Synthesis of Evidence, (5) Evidence-Based Guidelines, (6) Outstanding Issues that Warrant Research, and (7) Summary (which should provide both recommendations for best practices and recommendations for further research). The title of the article should begin with “Best Practices:”. For examples, please refer to the AJR Collection on Best Practices.

Highlights: Three bulleted key points (maximum 25 words per point) reflecting the article’s key messages.

Abstract: Maximum 200 words, unstructured.

Maximums: 4500 words; 100 References; 5 Tables, 12 Figures (30 total Figure parts).

 

Short Report

Hypothesis-driven research article based on a focused data set. These articles will generally present novel or exploratory findings that can be summarized more briefly than the investigations found in Original Research articles. The article is organized into the following four major sections: Introduction, Methods, Results, and Discussion

Abstract: Maximum 75 words, unstructured

Maximums: 7 authors; 700 words; 8 References; Figure parts and Tables combined cannot exceed 2. Tables should be short.

 

Clinical Perspective

GENERAL GUIDELINES FOR ALL SUBMISSIONS

  • All new and revised manuscripts submitted to the AJR are processed automatically through Similarity Check. Manuscripts that prove to be overly duplicative will not be accepted. Manuscripts may be returned to authors to appropriately address any duplicative content
  • The manuscript should be blinded so as to not reveal the authors’ identity. Authors’ names, initials and affiliations should not appear anywhere in the manuscript text or images. Redact the authors’ initials within the Methods section
  • References should not be redacted as this may indirectly identify the authors and thereby unblind the work. References to the authors’ earlier work should be provided in the third person (e.g., “as shown by an earlier investigation”) and maintain the full citation rather than being described in the first person (e.g., “as shown in an earlier study by our group”) with a redacted citation
  • Authors will be asked in Editorial Manager if the submission is based on a prior abstract or presentation, and if so, whether the authors retain the copyright to the earlier abstract. If the authors no longer retain the copyright to the abstract, then the authors must provide the earlier abstract, as well as a written statement from the sponsoring organization granting permission to use the abstract as a basis for the new article or indicating that permission is not required
  • Authors will be asked in Editorial Manager if there are any previous publications, including manuscripts accepted or under review, that might be regarded as the same or very similar work as the submission, as well as if there are previous publications, including manuscripts accepted or under review, with overlap in patient cohort. In the event of prior similar work or an overlapping patient cohort, the authors will be asked to explain further the nature of the overlap. In addition, the Methods section of the manuscript should cite the overlapping work and explain the difference between the prior and current studies. PDFs of the overlapping articles should be uploaded with the submission
  • Upon submission, the authors must attest that the manuscript does not include any materials copyrighted by other sources. This includes all tables and figures. If a table or figure is adapted from an earlier source, then the original source should be cited and both a copy of the original version and permission from the original publisher should be provided. Quotation of text of more than 50 words, as well as use of a different image slice from the same patient or case as in an earlier publication, will be considered an adaptation, and these same requirements apply.  Written permissions must indicate permission to reprint the material in both print and electronic media, including online use
  • To obtain permission from the AJR to reprint an AJR image, a form is available at http://apps.arrs.org/permissions. Once received, permission letters should be e-mailed to AJRsubmit@arrs.org with the author’s name, manuscript title, and manuscript number included
  • When accepted, all materials, including figures, tables, and supplemental materials, become the property of AJR/ARRS according to the terms of the Copyright Transfer and Author Certification Agreement

 

AUTHORSHIP

  • All authors must fulfill all criteria for authorship as described by the International Committee of Medical Journal Editors (ICMJE) Guidelines for Defining the Role of Authors and Contributors. The corresponding author attests to the criteria during the submission process. After submission, all co-authors receive an email with a link to a page in which they must attest to fulfilling these criteria
  • All authors must have approved the final submitted version of the manuscript (both for original and resubmissions) and are deemed accountable for the manuscript’s contents
  • If the number of authors appears disproportionate to the scope of work for a given submission, the journal reserves the right to request more information from the authors regarding each individual’s role in the conduct of the work. Simply having participated in the clinical care of the patients who are the subject of an article does not warrant inclusion as an author.
  • Adding or removing coauthors, or changing the order of authors, is not allowed after initial submission, including at the revision stage.  Added contributors may be acknowledged on the full title page at the time of resubmission.

 

RESUBMISSIONS

  • Resubmissions must be submitted through the online peer review system and include the following files:
  • A point-by-point detailed response to the Editors and/or reviewers’ comments, submitted as an MS Word document
  • Responses should be preceded by the reviewer and comment number (e.g., “Rev 2, Comment 4”) and the text of the reviewer comment
  • The response letter should be blinded (e.g., not provide the author’s name or institution or be on institutional letterhead) in the event that the resubmission is returned to external peer reviewers.
  • An annotated copy of the revised manuscript with changes tracked or highlighted. Changes should be identified by the reviewer number and comment number in the margins or in the text to make it clear to the Editors and/or reviewers which comment the change is addressing
  • A clean unannotated version of the revised manuscript (without any embedded figures)
  • All figures must be uploaded as individual TIFF or PNG files (even if there are no changes or revisions to the figures)
  • Resubmissions must adhere to the given article type’s limits for words, references, tables, figures, and figure parts, or else will be returned to the authors to be corrected. The authors are expected to adhere to all such limits in their resubmission even if additional text, references, tables, or figure parts have been requested by the reviewers or editors.

 

MANUSCRIPT ORGANIZATION

The manuscript is organized as follows: full title page, highlights (when required for the article type), abstract (when required for the article type), main manuscript text, references, tables, figure legends, and figures. Aside from the full title page (and figures for resubmissions) and supplemental data (if any), all of these components (including Highlights and Abstract, when required) should be submitted as a single Microsoft Word document. Pages must be numbered consecutively beginning with the abstract. Do not use line numbering.

 

Full Title Page

  • A separate Microsoft Word document that will not be included in the PDF that goes to the reviewers
  • Title of article
  • Type of article (i.e., article category)
  • Names, academic degrees, email addresses, telephone numbers, and complete institutional addresses (including zip code) of all authors and coauthors with one corresponding author clearly identified. Co-corresponding authors are not allowed. The Full Title Page is the primary source used when determining final order of authors at manuscript acceptance
  • Present addresses of authors who have moved since the study was completed
  • Funding sources (from grants and other sources)
  • Author disclosures, listed individually. If there are no disclosures, that fact must be explicitly stated.

 

References

  • References are numbered consecutively in the order in which they appear in the text.
  • All references are cited in the text, the reference numbers are enclosed in brackets, and are typed on line with the text (not superscripted)
  • Authors are responsible for the accuracy of cited references
  • Citations from internet sources should provide the name of the author(s), the title of the web page, the URL, the page’s original publication or creation date, and the date the page was visited
  • Unpublished data is not cited in the reference list but is cited parenthetically in the text, for example: (Smith DJ, personal communication), (Smith DJ, unpublished data). This includes papers submitted, but not yet accepted, for publication
  • Papers presented at a meeting are not cited in the reference list but are cited parenthetically in the text, for example: (Smith DJ, et al., presented at the 2003 annual meeting of the American Roentgen Ray Society). After first mention, use (Smith DJ, et al., 2003 ARRS meeting)

AJR Style Examples

  • Style and punctuation of references follow the format illustrated in the following examples. All authors are listed when six or fewer; when seven or more authors, the first three are listed, followed by et al. Inclusive page numbers (e.g., 333–335) are given for all references. Journal names are abbreviated according to Index Medicus.

2. Smith LW, Cohen AR. Pathology of tumors, 6th ed. Baltimore, MD: Williams & Wilkins, 1977:100–109

Chapter in a book

3. Breon AJ. Serum monitors of bone metastasis. In: Clark SA, ed. Bone metastases. Baltimore, MD: Williams & Wilkins, 1983:165–180

 

Tables

  • Tables should be included at the end of the manuscript MS Word file, following the References, and be in an editable format. Embedded images of tables, tables in MS Excel (.xls) format, and links to tables in other applications, are all not allowed.
  • Each table has a short, descriptive title, and each column has a heading
  • Tables do not exceed two pages in length and must contain at least four lines and two columns of data.
  • Tables are numbered in the order in which they are cited in the text. Each table should have a discrete number. Numbering tables as 1A and 1B is not allowed and is counted as two tables for total number of tables
  • Abbreviations are defined in an explanatory note below each table
  • Figures should NOT be embedded in table cells as these will not display correctly in the online version of the article

 

Figures and Figure Legends

  • Legends use AJR style: Fig. 1—47-year-old woman with rheumatoid arthritis. For each subject, supply age, sex, and condition or diagnosis. The AJR figure legend style (age and sex and diagnosis) helps specifically with search and retrieval algorithms, increasing the utility of the journal and its content
  • All figure parts relating to one patient should have the same figure number. Each figure part is considered an image when counting total number of images
  • Electronic manipulation of images that materially alters the medical information must be identified and the nature of the alterations described
  • Line drawings and graphs are in black on a white background, using the same size type as the text.
  • Authors’ names and hospital or institutional affiliations do not appear anywhere on the images. For peer review, artist names on images should be blinded or pixelated
  • Names or other personal-identifying information do not appear anywhere on the images. If person(s) are identifiable in the figure, authors must submit with the manuscript a permission form completed and signed by the identifiable person(s)

 

Figure Files

Original Submission

  • For the original submission, figures must be embedded in the MS Word document, at the conclusion of the manuscript following the References and any Tables. This will make it easier to submit the manuscript and will produce a PDF that is easier for the Editors and Reviewers to download
  • Figure legends should be directly above or below the corresponding image
  • Each figure part is counted as one image when counting total number of images

Resubmissions

  • For resubmissions, the files must be submitted as separate TIFF or PNG files. Other formats (e.g., JPEG, EPS, GIF, PICT, PowerPoint) or lower resolutions will not be usable
  • Images should be submitted in black and white unless color is necessary
  • Authors must use the following naming convention and submit a separate file for each figure part: Figure_01a.tif, Figure_01b.tif, Figure_02a.tif, etc
  • Image Size—All images should be no more than 5 inches in height or width
  • Black & white images: TIFF format, Grayscale mode, 300 DPI resolution, No layered files, No alpha channels, No color profiles assigned
  • Color images: 300 DPI resolution, No layered files, No alpha channels, Color profile if used: CMYK (No Indexed color, Lab, or RGB profiles)
  • Line art: 1200 DPI resolution, Grayscale or Bitmap mode, No layered files, No alpha channels, color profile if used: CMYK (No Indexed color, Lab, or RGB profiles)

 

Supplemental Data

  • For all article types other than Original Research, supplemental data is limited to video files or content not otherwise suitable for print
  • For Original Research articles, additional Methods, Tables, and Figures may be provided as supplemental data. All of the supplemental Methods, Tables and Figures must be provided within a SINGLE PDF file. This file should first contain the supplemental Methods (labeled eMethods), then all of the supplemental Tables (labeled eTable 1, eTable 2, eTable 3, etc.), followed by all of the supplemental Figures (labeled eFigure 1, eFigure 2, eFigure 3, etc). The supplemental Methods as well as all supplemental Tables and Figures must be called out in the manuscript text.
  • Authors must own the copyright to all Supplemental Data elements at the time of submission
  • The Supplemental Data will undergo external peer review along with the rest of the manuscript. For accepted manuscripts, the Supplemental Data will be made available online only without any further corrections, copyediting, or layout by the journal. A statement will be inserted at the start of the Supplement indicating that the Supplemental materials are in the form originally provided by the authors. The authors therefore will be accountable for such material’s accuracy

 

Video submission guidelines

  • File format: .mp4 preferred, but can accept .mov, .wmv, .mpg, .mpeg, or .avi (or .mp3 for audio files). No Flash or streaming video files
  • File size: up to 100 MB (split up videos into parts if larger)
  • Minimum dimensions: 320 pixels wide by 240 pixels deep
  • Maximum length: 10 minutes
  • Verify that the videos are viewable in QuickTime or Windows Media Player
  • If multiple video files are submitted, number them in the order in which they should be viewed
  • If person(s) are identifiable in the video, authors must submit with the manuscript a permission form completed and signed by the identifiable person(s)
  • All identifying information (unless the person has granted permission), brand or product logos, and institutional logos must be removed from any video components

 

Procedure for editor conflict-of-interest

  • For submissions for which the Editor-in-Chief or Section Editor has an institutional affiliation, the Editor with the affiliation will be recused and the manuscript will be handled exclusively by the other Editor. For manuscripts for which both the Editor-in-Chief and Section Editor have an institutional affiliation, or for which the Editor-in-Chief is a co-author regardless of whether the Section Editor has an institutional affiliation, an independent consulting editor-at-large will handle the manuscript
