1. CHARACTERISTICS AND CATEGORIES OF MANUSCRIPTS

The Korean Journal of Radiology, the official English language journal of the Korean Radiological Society, publishes original contributions valuable to the advancement of medical diagnosis and treatment. Published bimonthly in February, April, June, August, October and December, the journal reports clinical and other investigations relating to radiology and its allied sciences, publishing full-length original papers, reviews, pictorial essays, case reports, and letters to the editor.

The editorial office of The Korean Journal of Radiology expresses some concern over redundant publication. The Council of Science Editors defines redundant publication as reporting substantially the same work more than once, without attribution of the original source(s). A manuscript that is potentially redundant includes the following characteristics: (1) at least one of the authors has contributed to both or all reports (if there are no common authors, plagiarism is more likely than redundant publication); (2) the subject or study populations are often the same or similar; (3) the methodology is typically identical or nearly so and (4) the results and their interpretation generally vary little, if at all. The Korean Journal of Radiology accepts manuscripts describing original research only. 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. Manuscript decisions are based on the results of peer review, and to ensure that this is unbiased, reviewers receive manuscripts with blind title pages. Descriptions appearing in each article are the responsibility of the author and not of The Korean Journal of Radiology.

Authors are required to make clear the nature of their contribution to their manuscript. To be listed as an author at byline, an individual should have contributed substantially to all three categories established by the International Committee of Medical Journal Editors (ICMJE): (1) conception and design, or acquisition, or analysis and interpretation of data; (2) drafting the article or revising it critically for important intellectual content; and (3) final approval of the version to be published (www.icmje.org/index.html). The ICMJE further states that Acquisition of funding, the collection of data, or general supervision of the research group, by themselves, do not justify authorship. Korean Journal of Radiology strongly recommends that to be listed at byline, authors fulfill the ICMJE requirements. Individuals who have contributed substantially to some but not all of the three categories, or in other areas, should be listed in Acknowledgments .We also recommend limiting the number of authors not more than 9 in number. We do not allow the addition of authors or the changes of the first or the corresponding author after our initial decision to accept the manuscript for publication. If an author wish to be removed from the byline, he or she should submit a signed letter indicating his or her wish to be deleted from the list of authors. The change in the order in the byline requires a letter from all authors indicting agreement with the same.

Please write in English. For medical terms such as proper nouns, generic names of medicines, and units of measurement, use the original term. Abbreviation should be minimized. If employed, write the full terminology where it first appears, followed by its abbreviation in parenthesis, using the abbreviation thereafter. Radiation measurements and laboratory values should be in accordance with the International System of Units (SI) (resources: SI Units in Radiation Protection and Measurements, NCRP Report no. 82 [August 1985]; 'Now Read This: The SI Units Are Here,' JAMA1986;255:2329-2339.

3. GENERAL GUIDELINES FOR MAJOR PAPERS

Abstract:
Use a separate page, and observe a limit of 200 words. Clearly state the objective, materials (or subjects) and methods, results, and conclusion of the study. Include actual data.

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 recreate the experiment as closely as possible.

Results:
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.

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.

Acknowledgments:
Include here the names of those who contributed substantially to the work described in the manuscript but who have not fulfilled the requirement for authorship.

Include the following items on the title page: the title of the thesis, the name of the principal and other authors, along with current positions. When authors with a different address are included, first write the name of the organization where the primary research was conducted and the names of the other organizations along with the authors' names, listed in numerical order, with the numbering system beginning at the first organization. At the bottom of the title page, write the principal author's address, phone, fax and e-mail address, and if necessary, state the source of any research funding.

On the blind title page, write only the title of the manuscript. Do not include the authors' names, or other details.
