Original Research

Word Limit: 4750 words including abstract
Abstract - 250 words

Text, including references and tables - 4500 words

• NUMBER OF AUTHORS - 5-10 for retrospective studies; 10-15 for prospective studies.
• TITLE PAGE - The following information should appear: title of article; first name, middle initial, and last name of author(s); The title should be short, clear and informative, and to be in accordance to the content of the work. Avoid subtitles. State the full name of the institution where the work done and the place in which the institution is located. Identify the corresponding author and provide full mailing address, telephone/FAX numbers and e-mail address. Authors must indicate exactly how they want their names to appear.
• ABSTRACT - The abstract is limited to 250 words and should describe the essential aspects of the investigation in four subheadings: Introduction (The first sentence refers to previously known information relating to research); Purpose; Methods; Results (summarise data); and Conclusion (brief statement directed to the stated purpose or hypothesis). No cited references. Under the summary there should be a subtitle "Keywords" containing 3-10 key words or characteristic phrases.
• ABBREVIATION KEY - Please list abbreviations used within the abstract, text, legends, and tables along with their definitions. Abbreviations will appear on the first page of the printed article and should not be expanded in other portions of the manuscript. The Abbreviation Key will not be factored into an article's word count.
• INTRODUCTION - Should be brief and to provide the outline of the previous knowledge and experiences related to research, and to emphasize a link with the objectives of the work and summarize the reasons for the study.
• METHODS - This section may be divided into subsections if it enhances readability. The research design, patients/subjects, material used, means of confirming diagnoses and statistical methods should be included. Do not include results or discussion in this section. Do not include manufacturer’s names unless the specific product is important to the procedures performed; if the manufacturer’s name is included, list the city and state or country of the manufacturer. Indicate that informed consent has been obtained from patients who participated in clinical investigations. In animal experimentation, acknowledge that specific guidelines were followed.
• RESULTS - This section may be divided into subsections if it enhances readability. Present results in a clear, orderly fashion, and include statistical findings to substantiate the results. All results based on methods must be included. If tables and graphic material will ease the understanding of the results, include them. However, when the results can be summarised easily in a narrative form, do not use tables. Cite figures to illustrate findings.
• DISCUSSION - Start with limited, pertinent background information and then discuss the results of the investigation in light of what has been previously published, the limitations of your study, the implications for patient care and potential directions for future research. Indicate new and important facts that have been discovered in the work. Where appropriate, cite figures and graphs.
• CONCLUSION - In a separate section, summarise the major findings of the study and their clinical usefulness (if applicable). This paragraph should address the purpose stated earlier in the paper. Avoid definite statements and conclusions if not fully supported by the results.
  
- ACKNOWLEDGMENTS - Obtaining permission to include a name in this section from the acknowledged individual is advised.
• CONFLICT OF INTEREST - State whether a conflict of interest exists by incorporating one of the following statements: “EW (author initials) has a financial relationship with or consults for…” or “We declare that we have no conflict of interest”.
• FIGURES - The average one-column image plus legend equals 100 words; space taken up by figures must be subtracted from the text word count.
• REFERENCES - Provide only references that give essential background material. SEE ALSO: References

General Information

Electronic Format Requirements

We cannot publish your manuscript without receiving correctly formatted files.

Document Files

• Submit an electronic version of the manuscript as a Microsoft Word (DOC or DOCX) or RTF file. Please note that Abstracts and Keywords should be included in your main document in addition to being posted in the space provided in the electronic submission system.
• All text is to be paginated and double-spaced.
• Font: Times New Roman; font size at least 12 points.
• Preserve anonymity by ensuring that the authors’ names appear only on the title page (which should be a separate electronic file) and by eliminating references to institutions, affiliations, and previous work by the authors (stated as such in the manuscript) in any part of the paper, including the Acknowledgments or Conflict statement.
• Organise the manuscript as follows: Title Page (separate file); without Title Page - Abstract, Keywords, Introduction, Methods, Results, Discussion, Conclusion, Acknowledgments, Conflict of interest, References (separate file); Tables, Figures and Legends (separate file).
• Keep acronyms to a minimum. When an abbreviation is used, define it in the Abbreviation Key.

Figures and Legends

• SNR only uses electronic images. Submit all figures in JPG, TIF or EPS format.
• Each image should be a separate file with the figure number indicated in the filename.
• Legends should be in present tense (e.g., ‘DSA shows…’).
• Images should not be redundant. Avoid excessive illustrative material.
• Images should be uniform in size and magnification.
• Sagittal projections or lateral images are to be submitted with the patient facing the reader’s left.
• Illustrations should not have marks, circles or numbers in the area around the image and should be free of all identifying information relative to the patient and institution.
• Line drawings should be professional in quality and in black on a white background.
• Written permission for use of all previously published illustrations must be included with submission and the source should be referenced in the legends.
• Written permission from any recognisable person in a photo is required.
• Legends must be double-spaced, and figures and tables numbered in the order cited in the text.
• Label all pertinent findings.
• RESOLUTION REQUIREMENTS FOR JPG/TIF/EPS FILES:
  • Line Art (black and white) - 1200 DPI/PPI
  • Halftones - 300 DPI/PPI
  • Combination Halftones - 600 DPI/PPI
  • Images should be a minimum size of 4 inches wide at the stated resolution.

Electronic modification/manipulation of Image files

The following global changes to improve the quality of illustrations or remove identifying information are acceptable:

• changing image size and resolution as detailed above
• globally adjusting contrast and brightness (as long as no parts of an image are completely masked)
• blocking or erasing patient/institutional/manufacturer identifiers
• minimally "cleaning" unwanted noise in the background
• aligning an image that is tilted
• cropping unnecessary surrounding black space
• All cloning, whether completed to delete or enhance a part/s of an image is viewed as suspicious. No specific feature within an image may be enhanced, obscured, moved, removed, or introduced. Any manipulation of an image must be explained in the accompanying legend.

Tables

• Each table is displayed without vertical or horizontal rules.
• Prepare tables with word processing (e.g., Microsoft Word Table feature) or spreadsheet (e.g., Microsoft Excel) software. - Graphic files are not acceptable for tables.
• Type size may be reduced to accommodate high numbers of columns (tables may span more than one page).
• Each table has a short, descriptive title.
• Tables are numbered in the order cited in the text.
• Abbreviations are defined as footnotes at the bottom of each table.
• Tables should not duplicate data given in the text or figures.
• The “Results” section should refer the reader to the appropriate table.

References

The guidelines provided in this section are applicable to Original Research, Technical Notes and Review Articles.

• Section must be double-spaced.
• References are numbered consecutively in the order in which they appear in the text. All references must be cited in the text in square brackets, (e.g. [1] or [3-5] or [6, 8-10] etc,).
• Data such as abstracts from meetings should be cited in the reference list. For meeting abstracts, cite the authors, title, society meeting, date and location.
• Citations of personal communications should appear in the “Discussion” section only and should not be used to support the authors’ conclusions.
• Papers submitted but not yet accepted for publication should also be cited in the text (J. Byrne, unpublished data, 2011).
• Inclusive page numbers (e.g., 333-37) must be provided for all references.
• Journal names are abbreviated per Index Medicus.
• All authors are listed when there are three or fewer; where there are four or more authors, the first three are listed followed by “et al.”
