Guidelines for Registered Report Abstract Submissions
Overview
The European Society for Magnetic Resonance in Medicine and Biology (ESMRMB) is introducing registered reports as a new abstract submission format. This format is designed to enhance the rigour and transparency of research in magnetic resonance, including both method development and clinical applications. Registered reports outline planned research prior to data collection, focusing on the quality of methodology and statistical analysis rather than results.
What is a Registered Report?
A registered report is a research plan that is peer-reviewed before the research is conducted. For this conference, registered report abstracts describe your planned investigation including the rationale, hypothesis, methodology, and statistical analysis plan. Registered reports are particularly valuable for confirmatory (hypothesis-testing) research, but less suitable for exploratory research.
Suitable Abstract Categories
Clinical Research
Clinical studies are natural candidates for registered reports and should include:
- Clear hypotheses derived from prior evidence
- Detailed methodology including imaging parameters, subject recruitment criteria, and data analysis pipelines
- Appropriate statistical approaches with sample size justification
- Defined outcome measures with clinically meaningful thresholds
Method Development Research
Method development studies, while traditionally not considered candidates for registered reports, are suitable when they include a clear validation component. These submissions should:
- Provide preliminary data demonstrating technical feasibility (in vitro and/or initial in vivo data)
- Outline specific hypotheses regarding method performance (e.g., "The proposed method will achieve X% higher CNR for Y type of lesions compared to the current gold standard")
- Detail the validation approach with clear metrics of success
- Include a sample size justification based on preliminary data or literature
Required Components
All registered report abstracts must include:
1. Introduction
1.1. Background and motivation
- Concise background and rationale
- Clear gap in knowledge being addressed
- Relevance to clinical practice or technological advancement
1.2. Hypothesis
- Explicit, testable hypothesis or hypotheses
- For method development: specific performance metrics to be achieved
- For clinical studies: expected clinical outcomes or relationships
2. Methodology
Briefly describe how the preliminary data were obtained. For method-development abstracts, a section describing the novel method being presented should be included here.
3. Current Status and Preliminary Results
Submissions must include one or more of the following:
- Pilot data demonstrating technical feasibility of the proposed method, including:
- Initial in vitro validation results
- Preliminary in vivo testing
- Literature review with meta-analysis for expected effect sizes
- Initial exploratory study results that inform the confirmatory study design
4. Plan and Outlook
This is the most important part of the Registered Report as it contains the whole study plan.
4.1. Study protocol
- Study design and population
- MR acquisition protocol with detailed parameters
- Additional measurements or interventions
- For method development: implementation details and validation approach
- Data processing pipeline
4.2. Statistical Analysis Plan
- Primary and secondary outcome measures
- Statistical tests to be performed
- Sample size calculation with justification
- Anticipated effect sizes based on preliminary data or literature
- Handling of potential confounders
- Plan for missing data
5. References
Not added to the character count
Evaluation Criteria
Registered report abstracts will be evaluated based on:
- Scientific merit and innovation
- Methodological rigour
- Quality of preliminary data supporting feasibility
- Appropriateness of statistical approach and sample size justification
Important Notes
- Registered report abstracts are not "half abstracts" but complete research plans.
- Focus is on confirmatory rather than exploratory research.
- Preliminary data should be sufficient to justify the proposed approach.
- Registered reports represent a commitment to the outlined methodology.
- The authors of accepted abstracts are expected to submit the final results as a regular abstract to the ESMRMB congress the following year, by the usual abstract deadline in April or May. For the second stage submission, please state explicitly in the Introduction of the abstract that it is the second stage of a Registered Report. These second stage abstracts will be solely evaluated on the adherence to the stated plan, and will be accepted regardless of the positivity or negativity of the results.
- Selected first stage Registered Reports will be presented in a lightning talk session during the congress. All accepted Registered Reports will be presented as abstracts following the lightning talks. The poster presentation is intended to foster discussion, stimulate collaboration, and build momentum for the next phase of the project.
Submission Format
Abstracts should be submitted in structured format following the sections outlined above, with a maximum length of 5000 characters (excluding references). Up to two figures may be included showing preliminary data or methodological approach.
