Abstract submission guidelines
What AOCR 2027 asks for, how abstracts are reviewed, and the rules a submission has to meet. Read this before you start.

General guidelines
- Abstracts are submitted through this portal only. No e-mail or fax submission is accepted.
- The whole abstract body is limited to 400 words — the six sections counted together, excluding the title, the authors and their affiliations. The editor counts as you type and the submission is refused above the limit.
- The body is written in six sections: Purpose or Learning Objective, Methods or Background, Results or Findings, Conclusion, Limitations, and Funding for this study.
- Choose a preferred presentation format — oral presentation, poster presentation or student presentation. It is what you would prefer; the scientific committee decides.
- Say whether you are applying to a support programme: none, Invest in the Youth, or Shape Your Skills. The answer is recorded beside the abstract and is not itself an application — each programme has its own.
- Before submitting you answer the congress declarations: ethics committee approval, whether AI tools were used in writing, patient anonymity, and that the material is used lawfully.
- Abstracts are submitted in English only.
- One author may submit up to 5 abstracts — at most 3 posters and 2 oral papers.
- The first author is the presenting author. Up to 5 co-authors may be listed in addition.
- An abstract may be submitted once. The same work submitted again under a different title or author is not considered.
- The work must be the authors’ own, original and unpublished. Work already published or presented elsewhere cannot be submitted.
- Where material is borrowed from another source, the authors are responsible for obtaining permission, and the source must be cited in full.
- No image may show a patient’s identity — no name, no hospital identifier. Appropriate patient consent must be obtained.
- The title is written in sentence case. Avoid abbreviations in the title, keep them to a minimum in the body, and expand each one where it first appears.
- References may be included and count towards the 400-word limit.
- The abstract is attached as a PDF or a DOCX file, up to 20 MB. The format is verified from the file’s own contents, not from its name.
- Choose the sub-specialty that best fits the work. Up to two of the 23 sub-specialties may be selected for one abstract.
- An abstract may be withdrawn through this portal at any time before the deadline.
How abstracts are reviewed
- Every abstract is evaluated through a double-blind peer-review process by members of the scientific committee.
- Abstracts are judged on scientific, research and clinical value, on the originality of the work, and on its potential impact.
- The scientific committee’s decision — acceptance, rejection or a change of category — is final.
- The outcome is communicated to the presenting author by e-mail, and appears in this portal.
- The presentation is expected to reflect the abstract that was accepted. A substantial deviation, or a failure to present, is a matter for the scientific committee.
Oral papers
- Original research studies are encouraged for oral presentation.
- A proffered paper is 6 minutes.
- A prize paper is 8 minutes, with up to 2 further minutes for discussion. Some abstracts in each sub-specialty are selected for this category.
- Some papers may be converted to I.Shorts — a 3-minute presentation in an informal setting.
- Some paper abstracts may be converted to e-posters where the reviewers consider it appropriate.
- The final presentation is at most 20 MB, with at most 16 slides for a proffered or prize paper and at most 10 for an I.Short, counting the title, the closing slide and the references.
Sub-specialties
Choose the sub-specialty that best fits the work. Up to two of these 23 may be selected for one abstract.
The sub-specialty names are given in English. The scientific committee approved them in English and no other rendering has been approved, so they are shown as they were agreed.

E-poster categories
An e-poster belongs to one of these kinds. The kind is decided with the scientific committee after review; the submission form asks only whether the work is an oral paper or a poster.
I.POS.sci- A scientific exhibit: an original research paper — theme-driven research with a comprehensive report, a work-in-progress report of ongoing research, or a brief report of a new aspect of clinical radiology.
I.POS.edu- An educational exhibit of substantial or novel educative value — a review of a topic, a pictorial essay, a how-to demonstration. The abstract ends with two or three teaching points.
I.POS.cases- Isolated case reports. At least 3 cases are necessary, unless the condition is very unusual and of high educational value.
I.POS.signs- Radiologic signs on a theme, system, imaging appearance, pathology or organ: minimum 5 and maximum 10 signs, at most 12 slides.
I.POS.spotters- “Aunt Minnie” cases and typical findings: at most 5 spotters per system, each case on one slide with the answer and an explanation on the next, at most 12 slides including the title and end slide.
I.POS.playBy invitation, after review- A 5-minute oral presentation of selected high-quality posters in an informal setting in the poster hall. Offered on invitation after the complete e-poster has been reviewed; no separate abstract submission is necessary.
I.POS.printBy invitation, after review- A printed display of selected high-quality posters in the poster hall. Offered on invitation after review; no separate abstract submission is necessary.
Some of these rules this portal applies for you — the file format and size, how many abstracts one account may submit, the number of sub-specialties. Others, such as the word limit inside the file, the English-only rule and the removal of anything identifying a patient, are the author’s responsibility and are checked by the scientific committee. Nothing here is checked twice, and nothing that is not checked is presented as though it were.
