List of Contents

1. Aim and Scope

Neurointervention, an official journal of the Korean Society of Interventional Neuroradiology, publishes original articles documenting interventional neuroradiology. This journal was first published in 2006 under the title ‘Sin'gyŏng chungjae ch'iryo ŭihak’ and 'Neurointervention' (pISSN 1975-5643) and was renamed 'Neurointervention' in 2011 (pISSN 2093-9043, eISSN 2233-6273). Its title has been ‘Neurointervention’ since 2011. Neurointervention has been published twice a year on the first day of March and September until 2019 and has been published 3 times a year on the first day of March, July, and November since 2020.

The aim of the journal is to offer clinicians and researchers working in the neurointervention field peer-reviewed articles on clinical and basic investigation of the cerebral circulation and associated diseases for enhancing patient management, education, clinical or experimental research, and professionalism. Neurointervention publishes articles related to research and the practice of neurovascular diseases, including observational or outcome studies, clinical trials, epidemiology, health services, advances in applied (translational) and basic research, and current trends in cerebrovascular health issues.

The scope of the journal encompasses any areas of neurointerventional research, including those on pathophysiology, risk factors, symptomatology, imaging, and treatment. Research in basic science is considered only when it provides clinically relevant important information. Additionally, we are interested in studies that highlight characteristics of neurovascular diseases and stroke in Asian and Australasian populations. The journal publishes full-length original papers, reviews, technical notes, brief reports, case series, case reports, letters to the editor, commentaries, editorials, special reports, such as conference or meeting summaries, and medical cartoons.

The instructions for Neurointervention submissions are in accord with the “Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly work in Medical Journals” of the International Committee of Medical Journal Editors (ICMJE; www.icmje.org/recommendations), if not otherwise described below. Authors will be asked to confirm their compliance with the journal's policies and guidelines during manuscript submission on the web page, and each author will be asked to submit a signed "Conflicts of Interest and Copyright Transfer" document (available at Instructions & Forms at http://submit.neurointervention.org/) prior to acceptance of their manuscript.

2. Editorial Policies

Manuscripts are examined by the editor and usually evaluated by peer reviewers assigned by the editor. Both clinical and basic articles will also be subject to statistical review when appropriate. Provisional or final acceptance is based on originality, scientific content, and topical balance of the journal. Manuscript decisions are based on the results of peer review, and to ensure that the process is unbiased, reviewers receive manuscripts with blind title pages. Decisions are communicated by e-mail, generally within 8 weeks. All rebuttals must be submitted in writing to the editorial office. Descriptions appearing in each article are the responsibility of the author and not of Neurointervention. The editorial board will continuously work to monitor publication ethics and check manuscripts to confirm originality.

Peer review process for handling submissions from editors, employees, or members of the editorial board
All manuscripts from editors, employees, or members of the editorial board are processed in the same way as other unsolicited manuscripts. During the review process, submitters will not engage in the selection of reviewers and the decision process. Editors will not handle their own manuscripts, even if they are commissioned.

2-1. Research and Publication Ethics

Conflict of Interest
Conflict of interest exists when an author or the author’s institution, reviewer, or editor has financial or personal relationships that inappropriately influence or bias his or her actions. Such relationships are also known as dual commitments, competing interests, or competing loyalties. These relationships vary from being negligible to having a great potential for influencing judgment. Not all relationships represent true conflict of interest. On the other hand, the potential for conflict of interest can exist regardless of whether an individual believes that the relationship affects his or her scientific judgment. Financial relationships such as employment, consultancies, stock ownership, honoraria, and paid expert testimony are the most easily identifiable conflicts of interest and the most likely to undermine the credibility of the journal, the authors, or of the science itself. Conflicts can occur for other reasons as well, such as personal relationships, academic competition, and intellectual passion (http://www.icmje.org/conflicts-of-interest/). If there are any conflicts of interest, authors should disclose them in the manuscript. The conflicts of interest may occur during the research process as well; however, it is important to provide disclosure. If there is a disclosure, editors, reviewers, and reader can approach the manuscript after understanding the situation and the background of the completed research.
Authorship Criteria
Neurointervention defines an “author” as a person whose participation in the work is sufficient for taking public responsibility for all portions of the content. To be listed as an author at byline, an individual has to meet all four categories established by ICMJE (Defining the role of authors and contributors, http://www.icmje.org/recommendations/browse/roles-and-responsibilities/defining-the-role-of-authors-and-contributors.html): (1) Substantial contributions to the conception or design of the work, or the acquisition, analysis, or interpretation of data for the work; (2) Drafting the work or revising it critically for important intellectual content; (3) Final approval of the version to be published; and (4) 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.
If any persons do not meet the above criteria, they may be placed as contributors in the Acknowledgments section. Description of co-first authors or co-corresponding authors is also accepted, if the corresponding author believes that they equally contributed to the article. The corresponding author takes primary responsibility for communication with the journal during the manuscript submission, peer review, and publication process, and typically ensures that all the journal’s administrative requirements, such as providing details of authorship, ethics committee approval, clinical trial registration documentation, and gathering conflict of interest forms and statements, are properly completed, although these duties may be delegated to one or more coauthors.
Neurointervention does not allow adding authors or changing the first or the corresponding authors once its decision of ‘Accept as it is’ is made. If any author wishes to be removed from the byline, he or she should submit a letter signed by the author, as well as all other authors, indicating his or her wish to be deleted from the list of authors. Any change in the name order in the byline requires a letter signed by all authors indicting agreement with the same.
Publication and Research Ethics and Allegations of Misconduct
Neurointervention, adheres to the guidelines and best practices published by professional organizations, including ICMJE Recommendations and the Principles of Transparency and Best Practice in Scholarly Publishing (joint statement by the Committee on Publication Ethics [COPE], http://publicationethics.org/resources/guidelines; the Directory of Open Access Journals; the World Association of Medical Editors [WAME], http://wame.org/recommendations-on-publication-ethics-policies-for-medical-journals and Open Access Scholarly Publishers Association; the Directory of Open Access Journals[DOAJ] https://doaj.org/bestpractice).
Furthermore, all processes of handling research and publication misconduct shall follow the applicable COPE flowchart (https://publicationethics.org/resources/flowcharts).

For the policies on the research and publication ethics not stated in these instructions, Guidelines on Good Publication (http://publicationethics.org/) or Good Publication Practice Guidelines for Medical Journals (http://kamje.or.kr/) can be applied.

Manuscripts involving examinations of volunteers and patients must include a statement that the trial protocol has been approved by an institutional ethics review board (IRB) and that the subjects gave informed consent in accordance with the standards of the Declaration of Helsinki in its revised version that the World Medical Association has developed as a statement of ethical principles for medical research involving human subjects, including research on identifiable human material and data ( http://www.wma.net). Clinical studies that do not meet the Helsinki Declaration will not be considered for publication. Human subjects should not be identifiable, such that patients’ names, initials, hospital numbers, dates of birth, or other protected healthcare information should not be disclosed.

For animal experiments, it is expected that investigators will adhere to the Guide for the Care and Use of Laboratory Animals (National Academy of Sciences; https://www.nap.edu/catalog/5140/guide-for-the-care-and-use-of-laboratory-animals). and should get approval from the Animal Care Committee of the institution where the study took place.

For policies on any issues of research and publication ethics not stated in these instructions, the Guidelines on Good Publication (http://publicationethics.org/resources/guidelines) should be applied. The content of each article is the responsibility of the authors and not of Neurointervention.
Privacy Policy
Regarding privacy policy, publication consent form will be required in addition to IRB certificate and informed consent for procedure. Publication consent forms should be required for patient’s illustration in any article, especially any case report in which an individual or a group of individuals can be identified. This requirement also applies when a report involves deceased persons. Examples of identifying information are descriptions of individual case histories, photos, x-rays, or genetic pedigrees. Informed consent form for publication of Neurointervention is available at the Instructions for Authors (https://neurointervention.org/file/Informed_consent_form_for_NI.pdf) and required to submit to Neurointervention in the process of article submission.
Originality and Duplicate Publication
Neurointervention only accepts manuscripts describing original research. The editorial office of Neurointervention does not accept duplicate submission or redundant publication. Redundant (or duplicate) publication is publication of a paper that overlaps substantially with one already published in print or electronic media as defined by updated ICMJE guidelines regarding allegations of scientific misconduct. If authors believe their manuscript may be redundant, they should ask about this in a letter to the editor accompanying their submission.
In that letter, they should explain how their report overlaps with already published material, or how it differs. To help the editor determine the possibility of redundant publication, a copy of such published material may also be included. If excerpts from other copyrighted works are included, the author(s) must obtain written permission from the copyright owners and credit the source(s) in the article.

Manuscripts under review or published by other journals will not be accepted for publication in Neurointervention, and articles published in this journal are not allowed to be reproduced in whole or in part in any type of publication without permission of the Editorial Board. Figures and tables can be used freely if original source is verified according to Creative Commons Non-Commercial License. It is mandatory for all authors to resolve any copyright issues when citing a figure or table from a different journal that is not open access.
Process to Manage the Research and Publication Misconduct
When the Journal faces suspected cases of research and publication misconduct such as redundant (duplicate) publication, plagiarism, fraudulent or fabricated data, changes in authorship, undisclosed conflict of interest, ethical problem with a submitted manuscript, a reviewer who has appropriated an author’s idea or data, complaints against editors, and etc., The resolving process will be followed by flowchart provided by the COPE (http://publicationethics.org/resources/flowcharts). The discussion and decision on the suspected cases are done by Editorial Board.
How Neurointervention Handle Complaints and Appeals
The policy of Neurointervention is primarily aimed at protecting the authors, reviewers, editors, and the publisher of the journal. If not described below, the process of handling complaints and appeals follows the guidelines of the COPE available from: https://publicationethics.org/appeals.
Who Complains or Makes an Appeal?
Submitters, authors, reviewers, and readers may register complaints and appeals in a variety of cases as follows: falsification, fabrication, plagiarism, duplicate publication, authorship dispute, conflict of interest, ethical treatment of animals, informed consent, bias or unfair/inappropriate competitive acts, copyright, stolen data, defamation, and legal problem. If any individuals or institutions want to inform the cases, they can send a letter via the contact page on our website: https://neurointervention.org/about/contact.php.
For the complaints or appeals, concrete data with answers to all factual questions (who, when, where, what, how, why) will be provided.
Who is Responsible to Resolve and Handle Complaints and Appeals?
The Editor, Editorial Board, or Editorial Office is responsible for them. A legal consultant or ethics editor may be able to help with the decision making.
What may be the Consequence of Remedy?
It depends on the type or degree of misconduct. The consequence of resolution will follow the guidelines of the COPE.
Copyright
The copyright of published manuscripts is held by the Korean Society of Interventional Neuroradiology. Neurointervention permanently retains the copyrights to all manuscripts published in Neurointervention (including those submitted and approved for publication but not yet published) since 2006. Every paper published in Neurointervention is freely available via our website (https://neurointervention.org). Authors should complete and submit the Copyright Transfer Agreement be faxed, scanned as a PDF and emailed, or mailed to the editorial office. Hand-written signatures are required. Each author must read and sign the statements in the Copyright Transfer Agreement.
Registration of the Clinical Research and Data Sharing Policy
Neurointervention requires investigators to register their clinical trials (other than phase 1 or small device feasibility trials) in a public trials registry. This requirement will lessen the chance of publication bias by making all trials (published or unpublished) available to clinicians, investigators, and the public, even those that are negative or reflect unfavorably on a research sponsor’s product. Neurointervention follows the data sharing policy described in “Data Sharing Statements for Clinical Trials: A Requirement of the International Committee of Medical Journal Editors”. The ICMJE’s policy regarding trial registration is explained at http://www.icmje.org/recommendations/browse/publishing-and-editorial-issues/clinical-trial-registration.html. If the data sharing plan changes after registration this should be reflected in the statement submitted and published with the manuscript, and updated in the registry record.

Abstract

  • Describe each item separately in the following order.
  • Purpose: In 1 or 2 sentences, indicate the specific purpose of the article, and indicate why it is worthy of attention. The purpose stated here must be identical to the one given in the title of the paper and the introduction.
    Materials and Methods: Describe succinctly the methods used to achieve the purpose explained in the first paragraph, stating what was done and how bias was controlled, what data were collected, and how the data were analyzed.
    Results: The findings of the methods described in the pre- ceding paragraph are to be presented here with specific data. All results should flow logically from the methods described.
    Conclusion: In 1 or 2 sentences, state the conclusion of the study. This must relate directly to the purpose of the paper, as defined in the first paragraph of the abstract.
  • Do not use reference citations.
  • Keywords: At the bottom of the abstract, write 3-6 index terms, according to the index words referred in Medical Subject Heading (MeSH) in Index Medicus or on the inter- net site https://www.ncbi.nlm.nih.gov/mesh.

Main Text

  • Introduction: Briefly describe the purpose of the investigation, including relevant background information.
  • Materials and Methods: Describe the research plan, the materials (or subjects), and the methods used, in that order. Explain in detail how the disease was confirmed and how subjectivity in observations was controlled. When experimental methodology is the main issue of the paper, describe the process in detail so as to allow for recreation of the experiment as closely as possible.
    Present these in a clear, logical sequence. Because biometrics involves variations in exact measurements, follow the rule of using statistics when experimentation is described. If tables are used, do not duplicate tabular data in the text, but do describe important trends and points.
    Ensure correct use of the terms sex (when reporting biological factors) and gender (identity, psychosocial or cultural factors), and, unless inappropriate, report the sex and/or gender of study participants, the sex of animals or cells, and describe the methods used to determine sex and gender. If the study was done involving an exclusive population, for example in only one sex, authors should justify why, except in obvious cases (e.g., prostate cancer). Authors should define how they determined race or ethnicity and justify their relevance.
  • Results: Work should be reported in SI units. Undue repetition in text and tables should be avoided. Comment on validity and significance of results is appropriate, but broader discussion of their implication is restricted to the next section. Subheadings that aid clarity of presentation within this and the previous section are encouraged.
  • Discussion: Observations pertaining to the results of research and other related materials should be interpreted for your readers. Emphasize new and important observations; do not merely repeat the contents of the results.
    Explain the meaning of the observed opinion along with its limits, and within the limits of the research results, connect the conclusion to the purpose of the research. In a concluding paragraph, summarize the results and their meaning.
  • Conclusion: Provide a brief summary of results with any important recommendations and finish with some sort of judgment about the topic.

Acknowledgments

  • List all grants pertinent to the paper. In addition, authors must state whether they have any personal or institutional financial interest in drugs, materials, or devices described in their submissions.
  • Concise acknowledgment of contributors not listed as authors is welcome.

Author Contribution

  • To qualify for authorship, all contributors must meet at least one of the nine core contributions (concept and design, analysis and interpretation, data collection, writing the article, critical revision of the article, final approval of the article, statistical analysis, obtained funding, overall responsibility).
  • Example: Concept and design: DCS. Analysis and interpretation: DK, E-JS, and YSS. Data collection: DCS. Writing the article: DCS. Critical revision of the article: DK, E-JS, and DCS. Final approval of the article: DCS. Statistical analysis: DCS. Obtained funding: none. Overall responsibility: DCS.

The purpose of this series is not to focus on intense academic issues but rather to overview a recent trend with a learning point essential to trainees. In addition to the cartoon, the authors need to provide a summary of the topic with clear take-home messages. Maximum length for the article is 1,000 words. The word limit includes title page, medical cartoon, main body of text, bulleted take home points, acknowledgments, sources of funding, disclosures, and references. There may be no more than 8 illustrations for a medical cartoon. The manuscript does not include an abstract and contains as few references (less than 10) as possible.

7. Peer Review and Publication Process

Screening before Review

If the manuscript does not fit the aims and scope of the Journal or does not adhere to the Instructions to authors, it may be returned to the author immediately after receipt and without a review. Before reviewing, all submitted manuscripts are inspected by Similarity Check powered by iThenticate (https://www.crossref.org/services/similarity-check/), a plagiarism-screening tool. If a too high a degree of similarity score is found, the Editorial Board will do a more profound content screening. The criterion for similarity rate for further screening is usually 15%; however, the excess amount of similarity in specific sentences may be also checked in every manuscript. The settings for Similarity Check screening are as follows: It excludes quotes, bibliography, small matches of 9 words, small sources of 1%, and the Methods section.

Number of Reviewers

At least two reviewers will be selected from the list of reviewers by the handling editors. Therefore, manuscripts are peer reviewed by at least 2 or more experts in the corresponding field (basically, double-blind peer review). Reviewers recommended by the corresponding authors, if any, can be included as a reviewer.

Peer Review Process and the Author Response to the Reviewer Comments

The review period is 2 weeks. The first decision is usually made within a week after completion of the review.

The Editorial Board’s decision after the review will be one of followings: Accept, Minor revision, Major revision, Reject (resubmission allowed) or Rejection (no further consideration).

The Editorial Board may request the authors to revise the manuscript according to the reviewers’ comments. If there are any requests for revision of the manuscript by the reviewers, the authors should do their best to revise the manuscript. If the reviewer's opinion is not acceptable or is believed to misinterpret the data, the author should reasonably indicate that. After revising the manuscript, the author should upload the revised files with a reply to each item of the reviewer's commentary.

The decision to accept a manuscript is not based solely on the scientific validity and originality of the study content; other factors are considered, including the extent and importance of new information in the paper as compared with that in other papers being considered, the Journal's need to represent a wide range of topics, and the overall suitability for Neurointervention.

Decision letters usually, but not always, convey all factors considered for a particular decision. Occasionally, the comments to the authors may appear to be inconsistent with the editorial decision, which takes into consideration reviewers' comments to the editor, as well as the additional factors listed above. If the author(s) believe that the journal has rejected their article in error, perhaps because the reviewers have misunderstood its scientific content, an appeal may be submitted by e-mail to the editorial office (ksin@ksin.or.kr). Statistical editing is also performed if the data requires professional statistical review by a statistician. The board of editors reserves the right to edit a manuscript for phrasing, style, and overall content at any stage prior to publication, while maintaining the scientific accuracy of the manuscript.

Processing after Acceptance

If the manuscript is finally accepted, the proofreading will be sent to the corresponding author after professional manuscript editing and/or English proofreading. Proofreading should be performed again for any misspellings or errors by the authors. Before final proofreading, the manuscript may appear at the journal homepage or PubMed as an epub ahead of print with a unique DOI number for rapid communication. The epub ahead of print version will be replaced by the replacement XML file and a final PDF.

Feedback after Publication

If the authors or readers find any errors, or contents that should be revised, it can be requested from the Editorial Board. The Editorial Board may consider erratum, corrigendum or a retraction. If there are any revisions to the article, there will be a CrossMark description to announce the final draft. If there is a reader’s opinion on the published article with the form of Letter to the editor, it will be forwarded to the authors. The authors can reply to the reader’s letter. Letter to the editor and the author’s reply may be also published.
