Guidelines to the Authors

Hellenic Journal of Radiology

Guidelines for Authors

  Hellenic Journal of Radiology (“HJR”) is the official journal of the Hellenic Radiological Society, first published in 1968.
 This revived edition of HJR, published in English, aspires to promote scientific knowledge in Radiology both at diagnosis and image guided therapy, 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.
  HJR 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 medical imaging and related science specialists.   

1.    Language

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

2.    How to submit a paper

All submissions for peer-review should be performed online through the journal 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.

3. 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. 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.

The Hellenic Journal of Radiology will not hold legal responsibility should there be any claim for compensation.

All authors need to sign the copyright transfer form (link) and must have made substantial contributions as established by the ICMJE (

4. Conflict of interest disclosure

Each author needs to disclose any type of financial interest that is related to the study and might create a potential conflict. Funding of the study needs to be disclosed.

If there is no conflict of interest, this should be stated in the manuscript before the Reference section as follows: “The authors declared no conflicts of interest”.

5. Research ethics and compliance

The HJR follows the guidelines of the International Committee of Medical Journal Editors ( For all original articles a statement in the text of approval from the local ethics committee, a statement that research was performed according to the ethical standards as described by the Declaration of Helsinki and a statement that informed consent for participation in the study was obtained from all subjects, are required. In case of study with animals 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’.

6. Permissions and plagiarism

For the use of any figures already published elsewhere the authors are required to obtain written permission from the copyright owner(s) and to submit the evidence in the submission process.  Plagiarism will not be accepted in any case. Dedicated software will be used on this purpose; manuscripts with plagiarism will be returned to the corresponding author without consideration for peer review.

7. Types of manuscript

The HJR accepts the following types of articles:

-    Original articles: The paper needs to offer new knowledge on diagnostic or interventional radiology. The conclusions need to be sound and supported by statistical analysis. When the accuracy of a diagnostic test is assessed, following the Standards for Reporting of Diagnostic Accuracy (STARD) flow diagram ( is suggested. A structured abstract of 250 words, 3-5 keywords, text up to 4500 words, figures (up to four figures or eight figure parts), a maximum of six tables, a maximum of fifty references and a maximum of seven authors are required for original articles.

-    Review Articles: The journal may accept systematic reviews, meta analyses and literature reviews of a subject. An unstructured abstract of 200 words, 3-5 keywords, text of no more than 6000 words, figures (up to eight figures), a maximum of six tables, a maximum of a hundred references and a maximum of three authors are required for review articles.

-    Pictorial Essays: The purpose of pictorial essays is to provide a teaching message through high quality images. A brief text is required to accompany figures. An unstructured abstract of 200 words, 3-5 keywords, text of no more than 6000 words, a maximum of fifteen figures, a maximum of six tables, a maximum of a hundred references  and a maximum of four authors are required for pictorial essays.

-    Letters to the editor: Communication to the editor is welcome and will be published if they offer pertinent and/or constructive comment on articles published in Hellenic Journal of Radiology. Letters are published at the discretion of the Editorial team and should be received within three months after on-line publication of an article. Following acceptance, letters will be sent to authors for response. Letter communications should include text of no more than 500 words, up to two figures and ten references, without any abstract or keywords and a maximum of three authors.  

-    Clinical Case-Test Yourself: The purpose of the “Clinical Case-Test Yourself” manuscript is to offer readers the chance to test their skills in diagnosing rare disorders. The submitted cases should contain radiologic features that allow a narrow differential or an accurate diagnosis. The "Clinical Case-Test Yourself" manuscripts are not case reports with previously unreported imaging findings. The format for this manuscript consists of two parts. Part "A" represents the “Question” and consists of a title, a brief clinical history (maximum 100 words) and up to five figure parts with at least two showing pathology. The figure legends should only indicate the modality and should not reveal the abnormal findings. Part "B" represents the “Answer” and consists of a line statement of the diagnosis, and a Discussion of up to 1000 words, with no more than 10 references. In Part “B” the same figures as in Part “A” are repeated with the addition of explanatory legends and arrows. A maximum of ten references and a maximum of three authors are allowed.
