The Journal of Computer Assisted Tomography is a peer-reviewed, multidisciplinary journal whose audience is the general radiology community. The journal publishes a variety of original articles including original research, clinical investigations, review articles, invited commentaries, case series, and technical notes. It covers the spectrum of imaging techniques including computed tomography, magnetic resonance imaging, ultrasound, interventional related techniques and imaging, and the spectrum of nuclear medicine technologies. It also covers the spectrum of topics in the wider practice of radiology.

General Information on Manuscript Processing

Submitted articles are first evaluated by members of the editorial board regarding novelty, quality, ability to add to the existing literature, and whether they are suitable for the audience of JCAT. Next, editors decide whether submissions are suitable to proceed to external blinded peer-review. Editors subsequently assess the results of blinded peer-review. Final decision on acceptance of all articles rests with the Editor-in-Chief.

Ethical/Legal Considerations
All manuscripts submitted to JCAT should comply with the guidelines of the February 2006 consensus statement of the International Committee of Medical Journal Editors, Uniform Requirements for Manuscripts Submitted to Biomedical Journals (Section II. Ethical Considerations in the Conduct and Reporting of Research). A copy of this document can be found at the ICMJE Web site (

A submitted manuscript must be an original contribution not previously published (except as an abstract or preliminary report), must not be under consideration for publication elsewhere, and, if accepted, must not be published elsewhere in similar form, in any language, without the consent of Lippincott Williams & Wilkins. Each person listed as an author is expected to have participated in the study to a significant extent. Although the editors and referees make every effort to ensure the validity of published manuscripts, the final responsibility rests with the authors, not with the journal, its editors, or the publisher. All manuscripts must be submitted on-line through the journals Web site at See submission instructions on this page, under "On-line manuscript submission."

Policy on Preprints

A preprint is an early version of a manuscript that is made available to the public before peer-review by depositing it in one of several internationally recognized preprint servers; a preprint is not considered prior publication of the manuscript.

Publication on a preprint server must be disclosed in the cover letter of the submission and included in a section on the title page labeled: “Publication history”. Please use the following as an example:

“Publication history:  This manuscript was previously published in bioRxiv: doi:”.

If the manuscript is accepted, it is the author’s responsibility to update the preprint with a DOI and URL link to the final published version of the manuscript. The published version of the article or any interim versions produced while under peer review by JCAT must not be posted to the preprint server.

Patient, institution, and author anonymity and patient informed consent: It is the author's responsibility to ensure that a patient's anonymity be carefully protected and to verify that any experimental investigation with human subjects reported in the manuscript was performed with informed consent and following all the guidelines for experimental investigation with human subjects required by the institution(s) with which all the authors are affiliated. Authors should remove patients' names and other identifying information from figures.

If any identifying details appear in text, tables, and/or figures, the author must provide proof of informed consent obtained from the patient (i.e., a signed permissions form). Photographs with bars placed over eyes of patients should NOT be used in publication. If they are used, permission from the patient is required.

For purposes of blinded review, all hospital names and identifying information, as well as information that could identify the authors, should also be removed from the manuscript document. Information regarding authors should only be included on the title page and in letters to the editor to facilitate blinded review of the manuscript itself.

Conflicts of interest
Authors must state all possible conflicts of interest in the manuscript, including financial, consultant, institutional and other relationships that might lead to bias or a conflict of interest. If there is no conflict of interest, this should also be explicitly stated as none declared. All sources of funding should be acknowledged in the manuscript. All relevant conflicts of interest and sources of funding should be included on the title page of the manuscript with the heading “Conflicts of Interest and Source of Funding:”. For example:

Conflicts of Interest and Source of Funding: A has received honoraria from Company Z. B is currently receiving a grant (#12345) from Organization Y, and is on the speaker’s bureau for Organization X – the CME organizers for Company A. For the remaining authors none were declared.

Copyright: In addition, each author must complete and submit the journal's copyright transfer agreement, which includes a section on the disclosure of potential conflicts of interest based on the recommendations of the International Committee of Medical Journal Editors, "Uniform Requirements for Manuscripts Submitted to Biomedical Journals" (

A copy of the form is made available to the submitting author within the Editorial Manager submission process. Co-authors will automatically receive an E-mail with instructions on completing the form upon submission.

Open access
Authors of accepted peer-reviewed articles have the choice to pay a fee to allow perpetual unrestricted online access to their published article to readers globally, immediately upon publication. Authors may take advantage of the open access option at the point of submission. Please note that this choice has no influence on the peer review and acceptance process. These articles are subject to the journal's standard peer-review process and will be accepted or rejected based on their own merit.

The article processing charge (APC) is charged on acceptance of the article and should be paid within 30 days by the author, funding agency or institution. Payment must be processed for the article to be published open access. For a list of journals and pricing please visit our Wolters Kluwer Hybrid Open Access Journals page.

Authors retain copyright
Authors retain their copyright for all articles they opt to publish open access. Authors grant Wolters Kluwer an exclusive license to publish the article and the article is made available under the terms of a Creative Commons user license. Please visit our Open Access Publication Process page for more information.

Creative Commons license
Open access articles are freely available to read, download and share from the time of publication under the terms of the Creative Commons License Attribution-Non Commercial No Derivative (CC BY-NC-ND) license. This license does not permit reuse for any commercial purposes, nor does it cover the reuse or modification of individual elements of the work (such as figures, tables, etc.) in the creation of derivative works without specific permission.

Compliance with funder mandated open access policies
An author whose work is funded by an organization that mandates the use of the Creative Commons Attribution (CC BY) license is able to meet that requirement through the available open access license for approved funders. Information about the approved funders can be found here.

Read and Publish Agreements

Wolters Kluwer currently has read-and-publish agreements with institutional consortia listed here.

Corresponding authors who are affiliated with the participating institution and who qualify as eligible authors* can publish their eligible articles open access in the eligible LWW journals at no direct cost to them. Please see your institution’s individual policy for guidance on eligible article types and license choice. To qualify for the APC waiver, the corresponding author must provide their participating institution’s name and institutional e-mail address in the journal’s submission system. On acceptance, the corresponding author will be asked to place an open access order in the publisher’s payment portal where they will be able to request the APC be funded in accordance with this agreement. A $0.00 APC will then be applied.

*Eligible authors: Corresponding authors who are teaching and research staff employed by or otherwise accredited to one of the participating institutions as well as students enrolled or accredited to one of the institutions and who want to publish open access articles.

Compliance with National Institutes of Health Accessibility Requirements
The National Institutes of Health (NIH) requires authors to submit the “post-print” (the final manuscript, in Word format, after peer-review and acceptance for publication but prior to the publisher’s copyediting, design, formatting, and other services) of research the NIH funds to a repository that is accessible online by all without charge. As a service to our authors, LWW will identify to the National Library of Medicine (NLM) articles that require deposit and will transmit the post-print of an article based on research funded in whole or in part by the NIH to PubMed Central.

FAQ for open access

Permissions: Authors must submit written permission from the copyright owner (usually the publisher) to use direct quotations, tables, or illustrations that have appeared in copyrighted form elsewhere, along with complete details about the source. Any permissions fees that might be required by the copyright owner are the responsibility of the authors requesting use of the borrowed material, not the responsibility of Lippincott Williams & Wilkins. 

Authorship Guidelines

Each manuscript can have only one corresponding author. A maximum of two first authors is allowed and should be indicated on the title page of the submission and in the letter to the editor.  

All authors must fulfill all the criteria for authorship as described in the International Committee of Medical Journal Editors (ICMJE) Guidelines. If the number of authors is considered by the editors to be disproportionate to the scope of the work described in the submission, the editors reserve the right to request more information regarding the specific contribution of each author. 

To add or remove authors, or to change the order of authors after execution of the Copyright Transfer Agreement, authors must provide an explanation and each co-author must individually provide a consent for the change. It is at the discretion of the editors to allow such changes, and if considered inappropriate, may be considered grounds to reject the submission. Adding or removing coauthors, or changing the order of authors, is not permissible after acceptance. 

Involvement by Industry:

Authors involved with industry must indicate the titles of their work positions and their roles in the project on the title page. For the integrity of the study, data/information needs to be controlled by an individual, or individuals, without a conflict of interest, namely a nonemployee or nonconsultant. A statement should be put into the beginning of the methods section that data was under the control of such an individual(s) without a conflict of interest, including the initials of the individuals. These individuals should also be indicated as having this role on the title page. Such statements are needed for studies evaluating any industrial products, even if industry did not provide support for the study. 

Please also see “conflict of interest” section below.

Original Articles (Research).

For Original Articles (research), organize the manuscript into four main headings: Introduction, Materials and Methods, Results, and Discussion. This should be limited to 4500 words, 50 references, 5 Tables, and 15 images. Meta-analyses should be considered in this category and can have a maximum of 100 references. Statistical analyses are strongly encouraged where appropriate. If industry is involved, data must be under control of an individual without potential bias, and a statement to that effect must be put in the beginning of the Methods and Materials section and the role of the industry participant(s) indicated on the title page under affiliation.

Review Articles:

A Review article is an in-depth academic evaluation/analysis of a topic with an up-to-date comprehensive assessment of the literature that provides a valuable referenceable scholarly contribution to the radiology community. For Review articles, subheadings should be utilized to guide the reader and provide organization. These typically should be limited to 4500 words, with a maximum of 100 references and 5 Tables. Pictorial reviews should have similarly valuable text, and can have, at most, 35 high quality images, with each figure ideally having no more than 4 images.

Invited Targeted Commentary (General):

Commentaries are by invitation only. These may have headers, are at most 1200 words, with a maximum of 9 references, and at most 1 figure or one table. The title must begin with “Commentary:”

Invited Commentary (on article in current issue):

These commentaries are by invitation only. They are a commentary on an article to be published in the same issue. They are meant to provide a guide to the reader to best appreciate the most valuable points in the corresponding article. They are generally 300 words, with a maximum of 500 words, have at most 2 authors, have a maximum of 9 references, and no figures or tables. The title must begin with “Commentary:”

Technical Note:

These should cover a technical development, whether it is a new, or improved, imaging device/equipment, technique, or process/procedure. These are typically a maximum of 2000 words with a maximum of 25 references, 10 images and one table.

Case Series: The journal does not accept case reports. However, it will accept case series, typically 5 or more cases, that have notable importance to the radiology community. An example might be the first cases of imaging of a particular disease entity. They should provide important value to the literature, citable, and will be judged on that basis. These are typically 1500 words, a maximum of 25 references,10 images and one table.

General Principles for Manuscripts:

Abbreviations: Define abbreviations at first mention in text and in each table and figure. For a list of standard abbreviations, consult the Council of Biology Editors Style Guide (available from the Council of Science Editors, 9650 Rockville Pike, Bethesda, MD 20814) or other standard sources. Write out the full term for each abbreviation at its first use unless it is a standard unit of measure.

Brand Names, Products from Industry: If a brand name is cited, supply manufacturer's name and address (city and state/country). A format example would be “imaging was performed with multi-phasic contrast enhanced CT (Scanner Name, manufacturer’s name, City/Country).”

References: The authors are responsible for the accuracy of the references. Key the references at the end of the manuscript. Cite the references in text in the order of appearance. Cite unpublished data—such as papers submitted but not yet accepted for publication or personal communications—in parentheses in the text. If there are more than three authors, name only the first three authors and then use et al.

A) Creating Digital Artwork

  1. Detailed publication requirements/guides for Digital Artwork can be found at:
  2. Following the creation/scanning and saving of digital artwork, authors should check final figures for compliance with the Digital Artwork Guideline Checklist (below).
  3. Each figure’s images should be uploaded to Editorial Manager in conjunction with the manuscript’s text and tables.

B) Digital Artwork Guideline Checklist

The following are basic requirements that must be met before submitting digital artwork:

  • Artwork should be saved as TIFF, EPS, or MS Office (DOC, PPT, XLS) files. High resolution PDF files are also acceptable.
  • Any white or black space surrounding an image should be cropped out.
  • Diagrams, drawings, graphs, and other line art must be vector or saved at a resolution of at least 1200 dpi. If created in an MS Office program, the native (DOC, PPT, XLS) file should be submitted.
  • Photographs, radiographs and other halftone images must be saved at a resolution of at least 300 dpi.
  • Photographs and radiographs with text must be saved as postscript or at a resolution of at least 600 dpi.
  • Image size should be no smaller than 4 inches in the short axis, with a maximum of 7 inches in the long axis.
  • Each figure must be saved and submitted as a separate file. Figures should not be embedded in the manuscript text file.
  • Typically, a figure should have, at most, 4 images (rarely more). The more images that are present in a single figure, the smaller they will appear in print.
  • Annotations should be utilized (arrows, labeling, etc.) to enhance the value of images for readers. Annotations should be in black or white as JCAT is printed in grey scale.


  • Cite figures consecutively in the manuscript.
  • Number figures in the figure legend in the order in which they are discussed.
  • Upload figures consecutively to the Editorial Manager web site and enter figure numbers consecutively in the Description field when uploading the files.

Figure legends: Include legends for all figures. They should be brief and specific, and should appear on a separate manuscript page after the references. Use scale markers in images for micrographs, and indicate the type of stain used. All image annotations should be addressed in the figure legend. Legends for figures that include color images should include a statement at the end of the legend that “Figure X can be viewed online in color at”

Color figures: The journal accepts for publication color figures that will enhance an article. Authors who submit color figures will receive an estimate of the cost for color reproduction. If they decide not to pay for color reproduction, they can request that the figures be converted to black and white at no charge.

Tables: Create tables using the table creating and editing feature of word processing software (e.g., Word, WordPerfect). Do not use Excel or comparable spreadsheet programs. Group all tables in a separate file. Cite tables consecutively in the text, and number them in that order. Key each on a separate page, and include the table title, appropriate column heads, and explanatory legends (including definitions of any abbreviations used). Do not embed tables within the body of the manuscript. They should be self-explanatory and should supplement, rather than duplicate, the material in the text. Tables should not exceed two pages in length.

Style: Pattern manuscript style after the American Medical Association Manual of Style (9th edition). Stedman's Medical Dictionary (27th edition) and Merriam Webster's Collegiate Dictionary (10th edition) should be used as standard references. Refer to drugs and therapeutic agents by their accepted generic or chemical names, and do not abbreviate them. Use code numbers only when a generic name is not yet available. In that case, supply the chemical name and a figure giving the chemical structure of the drug. Capitalize the trade names of drugs and place them in parentheses after the generic names.

Supplemental Digital Content: Authors may submit supplemental digital content via Editorial Manager to enhance their article's text and to be considered for online-only posting. Supplemental digital content may include the following types of content: text documents, graphs, tables, figures, graphics, illustrations, audio, and video. Cite all supplemental digital content consecutively in the text. Citations should include the type of material submitted, should be clearly labeled as "Supplemental Digital Content," should include a sequential number, and should provide a brief description of the supplemental content. Provide a legend of supplemental digital content at the end of the text. List each legend in the order in which the material is cited in the text. The legends must be numbered to match the citations from the text. Include a title and a brief summary of the content. For audio and video files, also include the author name, videographer, participants, length (minutes), and size (MB). No patient-identifying information should be used in supplemental digital content unless written consent from the patient, the patient’s parents or the patient’s guardian has been obtained. Documentation regarding this consent must be submitted with the manuscript. Copyright and Permission forms for article content including supplemental digital content must be provided at the time of submission.

Supplemental Digital Content Size & File Type Requirements:
To ensure a quality experience for those viewing supplemental digital content, it is suggested that authors submit supplemental digital files no larger than 10 MB each. Documents, graphs, and tables may be presented in any format. Figures, graphics, and illustrations should be submitted with the following file extensions: .tif, .eps, .ppt, .jpg, .pdf, .gif. Audio files should be submitted with the following file extensions: .mp3, .wma. Video files should be submitted with the following file extensions: .wmv, .mov, .qt, .mpg, .mpeg, .mp4. Video files should also be formatted with a 320 X 240 pixel minimum screen size. For more information, please review LWW's requirements for submitting supplemental digital content:

Resubmission Process

If invited to resubmit, please follow instructions for formatting above as well as the following.

Please number reviewer/editor comments and respond to them point by point in the letter to the editor, for example "Reviewer 1, comment 1.” Please also indicate the changes/updates made in the manuscript in response. A change can be just a clarification.

Address each comment both in the responding letter, and as improvements/clarifications within the manuscript itself, using the comments function of the word processing program to indicate which changes in the manuscript refer to which numbered comment. Please do not respond only in the letter to the editor without making changes/clarifications in the manuscript.

Submit two versions, a “clean” version, and a second version where the changes made have been highlighted with the Comments feature of the word processing software used for the manuscript. Use the Comments feature to indicate which changes in the document correspond to which changes in the letter to the editor, “e.g. Reviewer 1, Comment 1,” “Associate Editor, Comment 3”, “Editor-in-Chief, Comment 2,” etc.

Double space and number all pages in the manuscript to facilitate review.

Visual Highlights

The journal requires that revised manuscripts include a Visual Highlights document. In the event a manuscript is accepted, this document will be used to promote the work on the journal’s various social media channels. It will also be available alongside the published article on the JCAT website. The file will be accessible for free to all website visitors.

Please note that all Visual Highlights are reviewed by the journal’s Social Media Editor, and may be edited prior to publication. All images used for the Visual Highlights file must be either in the public domain or originally created by the author(s).

Once a manuscript has evolved to the stage of requiring only minor changes, authors will be asked to create visual highlights, based on a PowerPoint template (link will be provided in the instructions to authors for minor changes). Link is also provided here for reference.

The purpose of visual highlights is to provide succinct information that can be posted on social media. The visual highlight itself is a single-slide presentation of the most important 1–2 images, and important points, from the manuscript. It is NOT a summary of the paper, an abstract of the paper, or a scientific presentation of the paper. It should be visually appealing and use a minimum of text.

Instructions for Visual Highlights

  • Complete “Title/Purpose” field with the title or purpose of the accepted paper.
  • Insert Graph/Figure/Image on the left from accepted paper (maximum of 2).
  • Insert up to 3 key points or interpretation of Graph/Figure/Image (max 75 words, font size 20)
  • At the bottom of the page, insert the first author only and et al., year of publication and DOI. 

After Acceptance
Electronic page proofs and corrections:
Corresponding authors will receive electronic page proofs to check the copyedited and typeset article before publication. Portable document format (PDF) files of the typeset pages and support documents (e.g., reprint order form) will be sent to the corresponding author via e-mail. Complete instructions will be provided with the e-mail for downloading and marking the electronic page proofs. Corresponding author must provide an e-mail address. The proof/correction process is done electronically.

It is the author's responsibility to ensure that there are no errors in the proofs. Changes that have been made to conform to journal style will stand if they do not alter the authors' meaning. Only the most critical changes to the accuracy of the content will be made. Changes that are stylistic or are a reworking of previously accepted material will be disallowed. The publisher reserves the right to deny any changes that do not affect the accuracy of the content. Authors may be charged for alterations to the proofs beyond those required to correct errors or to answer queries. Electronic proofs must be checked carefully and corrections returned within 24 to 48 hours of receipt, as requested in the cover letter accompanying the page proofs.

Reprints: Authors will receive an email notification with a link to the order form soon after their article publishes in the journal ( Reprints are normally shipped 6 to 8 weeks after publication of the issue in which the item appears.
