Author Guidelines

Author Guidelines

  1. Scope

Obstetric and Gynecological Imaging (“OGI”) is the official journal of the Hellenic Society of Ultrasound in Obstetrics and Gynecology, first published as “Ultrasonography”. This revived edition under the name of OGI, published in English, aspires to promote scientific knowledge in obstetric and gynecological imaging, and further to expand on related topics that are significant for the clinical obstetric and gynecological practice, worldwide. It is a peer-reviewed Journal, aiming at raising the profile of current evidence-based imaging practice and at improving the scientific multidisciplinary dialogue. OGI presents clinically pertinent, original research and timely review articles. It is open to international authors and readers and offers a compact forum of communication to clinical imaging and related science specialists.


  1. Language

American English is the official language of the journal. All submitted manuscripts should be written in American English.


  1. How to submit a paper

All submissions for peer-review should be performed online through the journal’s website

The Editorial office and the Editor-in-chief will perform the initial assessment of the manuscript and if the manuscript is suitable for the journal and the submission is complete, it will be sent to the relative reviewers. The reviewing process that is followed is double blinded. During on-line submission, authors can enter the name/s of non-preferred reviewers. The time allocated for reviewers to assess the manuscript and submit their recommendation is three weeks. The Editor-in-chief makes the final decision for publication.
The Editorial office will communicate the reviewer’s comments and the decision to the authors.


  1. Manuscript originality and copyright

The submitted manuscript should be original, should not contain previously published material and should not be under consideration for publication in another journal. Previous publication of an abstract as an oral presentation or scientific exhibit, either in print or electronically, does not preclude submission of an original article for publication. Any potential overlap with prior publications should be clearly stated by the authors to avoid redundant publications. The submission needs to be approved by all co-authors and, in case of original research; a ‘guarantor’ of the study is required. As ‘guarantor’ may be considered a senior author that is deemed to take overall responsibility for all aspects of the study (ethics, originality, consent, data handling, and all aspects of Good Medical Practice). The ‘guarantor’ of the study does not necessarily need to be the corresponding author. OGI will not hold legal responsibility should there be any claim for compensation. All authors need to sign the copyright transfer form ( Transfer Form.doc).


  1. Ethical issues

Authorship and contributorship

Authorship should be based on the criteria defined by the International Committee of Medical Journal Editors recommendations(


Complaints and appeals

The Editorial Board (EB) will discuss in detail all the complaints and appeals on the decision of rejection of a submitted manuscript or any concerns or allegations regarding misconduct, and will decide accordingly. An independent panel of international experts, including renowned journal editors and directors of academic departments, may be consulted if these issues arise.

Conflict of interest - competing interests

It is the authors’ responsibility to fully disclose in the cover letter any financial interests (shareholding or employment by industry, etc.) relative to the work under consideration. Any conflict should be stated in the manuscript before the Reference section. Authors should acknowledge any source of funding provided for the submitted subject matter (i.e. grants, financial support for presentations at meetings, etc). For clinical trials, the registration number, if available, should be included. Advertisements will be kept out of the main text body of the journal and it is the Editor’s responsibility that the editorial decisions will not be influenced by advertisers and sponsors. Special issues follow the routine editorial process and are by no means influenced by advertisers. The EB retains the right to refuse any advertisement for any reason.

Data sharing and communication

The EB may permit the use of figures or text for scientific reasons. Audits of rejection rates, review of completion time and other data, such as the impact factor of the journal, will be regularly published. Premature publication in the mass or social media is not advised until the article has appeared electronically in public.

Patient data

It is the authors’ responsibility to protect patient anonymity. All identifying data (name, identification numbers, initials) must be removed from text, images and tables. If it is mandatory for a patient’s face to be included in the manuscript, the eyes should be sufficiently masked. If there is a possibility that a patient may be identified from a photograph or relevant legend and text, the patient’s written consent should be submitted.



Research ethics and compliance

OGI follows the guidelines of the International Committee of Medical Journal Editors ( It is the authors’ responsibility to confirm that any experimental investigation on human subjects reported in a submitted manuscript has been performed with the subjects’ informed consent and following the approval of the appropriate institution review board. For prospective clinical studies with human subjects, the authors are required to confirm that both an appropriate institution review board approval and informed consent have been obtained. For retrospective clinical studies, the authors are required to confirm than an institution review board waiver of informed consent has been obtained. For clinical studies involving human subjects with no access to ethics review committees, the authors should confirm that they followed the principles outlined in the Helsinki Declaration (World Medical Association Declaration of Helsinki: ethical principles for medical research involving human subjects. JAMA 2013; 310(20): 2191-2194). Authors may be asked to document the above at any time point.
Prospective studies with human subjects are required to provide both an appropriate institution review board approval and informed consent. Retrospective studies are required to provide an institution review board waiver of informed consent. Authors may be asked to document the above at any time point.

For studies involving animals, the authors should indicate whether the procedures followed the local regulatory principles on animal experimentation. In this case, the following statement needs to be added in the text: “All applicable international, national, and/ or institutional guidelines for the care and use of animals were followed”.

Permissions and plagiarism

Figures and images should have not been previously published. For the use of any figures already published elsewhere by one of the authors or by means of another publication, the authors are required to obtain written permission from the copyright owner(s) and to submit the evidence in the submission process. Disclosure should be made at the time of submission, accordingly.
Plagiarism will not be accepted in any case. Dedicated software will be used on this purpose. All submissions will be first screened by a similarity detection software before being assigned for peer review. If the overall text similarity index is >20%, or the duplication rate is >5%, the manuscript is returned to the authors without peer review. The similarity report will be included in the editor’s message. In cases of plagiarism, citation manipulation, data and results fabrication, or any suspicion of research misconduct, the EB will follow the guidelines of the Committee on Publication Ethics

( The EB reserves the right of rejecting submissions if there is any doubt about whether the procedures described above have been followed accurately.


Options for publication, post-publication discussions and corrections
All manuscripts are subjected to blind peer review after being initially assessed for quality by the section editors. The section editors will first evaluate the possibility of duplicate publications. Reviewers are selected for their known expertise, objectivity and proven commitment and professionalism.
Reviewers should handle the material confidentially and are not allowed to share or copy. In case of major disagreement between two reviewers, the manuscript will either be assigned to a third reviewer, or the section editor will make a decision. The decision on acceptance or rejection is based solely on the reviewers’ evaluation, the importance of the manuscript and its relevance to the aims of the journal. The EB will decide upon any letters to the editor commenting on prior publications. Corrections on prior publications related to authors’ names, affiliations, major flaws or any kind of errors will also be discussed by the EB and prompt changes will be published in a subsequent issue. The changes will be listed in the table of contents to ensure that they will be linked to the initial publication to which they pertaining major databases such as PubMed.
