I. General policy

The Journal of Neurosonology and Neuroimaging (J Neurosonol Neuroimag, JNN) is a regular academic journal of Korean Society of Neurosonology, publishing all studies related to neurosonology and neuroimaging in the field of stroke, cerebrovascular or other neurological diseases. The JNN offers full coverage of all the relevant stroke or cerebrovascular aspects of neurosonology including transcranial Doppler, carotid duplex ultrasound, and neuroimaging modalities such as MRI, CT, SPECT, or PET. It is also interested in the field of peripheral nervous system based on ultrasound or imaging. Basic sciences can be welcome if the results are closely relevant to clinical practice. The submission policy is based on the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly work in Medical Journals issued by the International Committee of Medical Journal Editors (https://www.icmje.org/recommendations/). What is not stated in this instruction follows the general principles of the above format.

1) Submission and author

Submitting author must be member of the society or qualified by the editing committee. Author of the study must have contributed fully for the study and who can take responsibility for the contents of the study. Qualification for author is limited to who has contributed in setting of basic concept of the study, design of the study, analysis, and interpretation of the data, or who have contributed in writing the manuscript, and who agree to the contents of the contents of the manuscript.

2) Duplicate publication

What has been published in other journals is not allowed for submission in our journal. Any study published through our journal must not be published in other journals without any permissions.

3) Types of manuscript

‘Original article’, ‘Scientific statements’, ‘Review’, ‘Case report’, ‘Education section’, and ‘Editorial’ appointed by the committee of publication can be considered for peer-reviewed publication in Journal of Neurosonology and Neuroimaging.

4) Paper review policy

All submitted papers are reviewed by more than two experts on the topic, and review by the editing committee decides upon the publication. The editing committee may put corrections to the manuscript within the scope of not affecting the original contents. Once rejected for publication, the manuscript is not reviewed any more.

5) Ethical policy

A submitted manuscript must not be associated with any type of research misconduct, including fabrication, falsification, or plagiarism with intent to deceive by the authors. The Editor-in-Chief will reject a manuscript if research misconduct is suspected. The cover letter to the Editor-in-Chief must declare that a submitted manuscript has neither been published nor is under simultaneous consideration for publication elsewhere either in its entirety or in part in any language, except in the form of an abstract. The cover letter must also state whether any part of the manuscript contains redundant or duplicate information, defined as text, data, tables, or figures that overlap substantially with previously published information. Research involving human subjects must comply with the principles of the Declaration of Helsinki (1964), and manuscripts describing such research must state that informed consent was obtained from the subjects, when appropriate. Manuscripts describing research involving animals must state in the Methods section that the work was approved by the appropriate institutional ethics committee or review board. It is also recommended to write together the number of institutional review board, even if the requirement for informed consent was waived. Policies on the research and publication ethics not stated in these instructions are available elsewhere, such as in the "Committee on Publication Ethics" (https://publicationethics.org/resources/Guidelines). In any possibility of exposing the patient’s (or even the hospital employee’s) personal information like the patient’s (hospital employee’s) picture of the face, prior permission from the patient (hospital employee) or his/her guardian should be obtained, and it should also be specified in the manuscript.

6) Quotation of previously published data

Any quotation of figures or graphs from other previous publication should go through permission of the original author and be elucidated on the paper.

7) Costs to authors

There are no page charges to authors, however, authors must select the Copyright Transfer Agreement and remain within the word limit per article types.

8) Copyright

The copyright of the published manuscripts in JNN is held by the Korean Society of Neurosonology.

II. Manuscript Preparation

1) Article types

(1) Original article

• An abstract is no longer than 250 words and should be provided with the following headings: Background, Methods, Results, and Conclusion. The maximum length for original manuscripts is no more than 6,000 words including the title page, abstract, text, acknowledgments, sources of funding, disclosure, tables, figure legends, and references.

Additional tables and figures may be provided using the online supplemental data system. Citation with irrelevant or numerous references should be avoided.

(2) Scientific Statements

• Scientific statements are an official point of view which educates basic or clinical scientists, and clinical physicians on the scientific basis of neurological disease and on how this knowledge can be relevant in clinical practice. They may or may not contain clinical or research recommendations. Topics are selected based on their emerging scientific impact on neurological disease and their clinical application to the general population. Scientific statements contain scholarly synopsis of a topic related to neurosonology and/or neuroimaging.

(3) Review

• Review is a manuscript focused on a specific title, appointed by the editing committee, and published after certain screening. Abstract is required but does not need to follow the structured format of an original article. Articles of this type should not exceed 10,000 words, not including references, tables, and figure legends. Please limit references up to 100.

(4) Case report

• Case reports are limited to when the case is rare, special or of clinical importance which can offer considerable insight into controversial disease entity. The maximum length for case report is 1500 words and two tables and/or figures. An abstract is unstructured and should be less than 150 words. The reference is limited to 10. The JNN requires providing author’s reason for reporting the case in a separate cover letter.
• Updated October 2020: It is mandatory to obtain patient consent for publication in JNN regarding information on demographic data, medical condition, treatment, prognosis, photographs, images, videos, or genetic information from the patient himself or an immediate or legal guardian (https://www.j-nn.org/file/informed_consent_form_ENG.pdf or https://www.j-nn.org/file/informed_consent_form_KOR.pdf). In case of not being able to obtain the consent, authors may request waiver of consent to institutional review board. Hand-written signatures are required by author and patient/guardian and the informed consent form is to be uploaded as Supplement file.

(5) Education section

• Education section is composed of interesting findings for neurosonology or neuroimages unpublished before. It should be particularly clear examples of established observations intended for the trainee audience. Educational videos may also be submitted under this category. An abstract is not required, and the maximum length is 1500 words and the total number of figures and/or tables is limited to 2. The reference is limited to 10. The JNN requires the author’s reason for reporting as an Education in a cover letter.

(6) Editorial

• Any constructive criticism or opinion on a specific and important paper published in Journal of Neurosonology and Neuroimaging may be stated. Words counts and total number of references are not limited, and subheadings should not be used.

2) Copyright

The Korean Society of Neurosonology requires that the Copyright Transfer Agreement (https://www.j-nn.org/file/Copyright_Transfer_and_Author_Consent_Form.pdf) accompany all submissions. Electrical or hand-written signatures are required by corresponding author and the consent form is to be uploaded with online submission.
