29th INTERNATIONAL CONFERENCE ON MEDICAL IMAGE COMPUTING
AND COMPUTER ASSISTED INTERVENTION
4-8 OCTOBER 2026ADNEC CENTRE/ABU DHABI

CALL FOR CHALLENGES

This year all satellite events are required to submit a Letter of Intent (LOI). If you are considering submitting a Workshop proposal for MICCAI 2026, you must send an LOI by December 15, 2025 to the following link: https://cmt3.research.microsoft.com/MICCAISAT2026/Submission/Index.

Full proposals are due January 9, 2026.

MICCAI Challenges provide a fair, transparent, and robust environment for evaluating solutions to common problems in our field. They have become a cornerstone of the MICCAI conference, bringing together diverse teams worldwide to work on shared benchmarks and exchange ideas—accelerating state-of-the-art progress and enabling efficient dissemination of new results.

We are pleased to announce the Call for Challenges for the MICCAI 2026 conference in Abu Dhabi, UAE. We invite researchers, clinicians, and industry professionals to propose innovative challenges for MICCAI 2026 that address timely problems in medical image analysis (MIC) and computer-assisted interventions (CAI). We welcome challenges in all areas relevant to MICCAI, including but not limited to:

  • Medical image segmentation, registration, and reconstruction
  • Computer-aided diagnosis and prognosis
  • Image-guided interventions and robotics
  • Machine learning and deep learning in medical imaging
  • Multi-modal image analysis
  • Computational anatomy and physiology
  • Surgical planning and simulation
  • Foundation models
  • Vision-language models and tasks
  • Integration of imaging and non-imaging data (clinical, EHRs, genetics, omics…)

Proposals that explicitly address fairness, global health, and barriers to clinical translation are especially welcome. Regarding overcoming barriers to clinical translation, proposals may for instance address: clinically informed choice of metrics and outcomes, real-life data, systematic assessment of out-of-distribution generalization (different devices, diverse populations…), well-powered challenges allowing robust statistical conclusions etc.

Local Challenges

We highly encourage the proposition of challenges from the Middle East area. Potential organizers may contact the Challenge Organizing Team MICCAI Challenges Team (miccai-challenges-2026@dkfz-heidelberg.de) for assistance in preparing their proposal.

Collaboration with European Society of Radiology (ESR)

In collaboration with European Society of Radiology (ESR), we also announce special clinical interest topics with associated clinicians who can help with the preparation of the proposals; the best 3 challenge proposals on these topics will get the opportunity to also present their challenges at the European Congress of Radiology (ECR) 2027 in a special session:

  • Detection and quantification of colorectal liver metastasis on CT
  • Quantification of Osteoporosis on CT
  • Prediction of pulmonary function based on a single chest CT scan
  • Automated RECIST assessment on baseline and follow-up Thorax-Abdomen CT
  • AI-based Positive Assessment of Brain Imaging in Multiple Sclerosis (MS)
  • AI-based assessment of PET imaging for oncology
  • AI-based generation of full radiology report from imaging
  • Ultrasound, Doppler, and MRI-Based Multimodal Segmentation and Characterization of Parotid Tumours
  • From single to multi-sequence synthetic MRI for MSK imaging

If you want to organize a challenge in collaboration with ESR on one of these topics, please reach out to the MICCAI Challenges Team (miccai-challenges-2026@dkfz-heidelberg.de) and we will put you in contact with the corresponding clinician.

Open data

MICCAI supports open data; we encourage organizers to use open-source data licenses and/or keep challenges open beyond the conference to provide a sustained benchmarking platform.

Proposal Requirements

MICCAI membership: Either the lead organizer or at least one other organizer must be a MICCAI Society member at the time of submission (https://miccai.wildapricot.org/).

Submission Process

Note: Uploading a design document that is incomplete or differs from the one generated by the structured system will result in desk rejection.

Make sure you select the "CHALLENGES” track in CMT

Selection Criteria

Proposals will be evaluated on:

  • Potential impact on research and practice
  • Relevance to the MICCAI community
  • Quality and novelty of the challenge design

To ensure a rich and diverse program, the committee may request mergers for substantially overlapping proposals, scope adjustments, supplementary materials, or revisions prior to acceptance.

Post-Acceptance Process

  • Upon acceptance of the challenge, the complete challenge design will be registered on Zenodo by the MICCAI SIG for Challenges. Any changes (e.g., metrics, ranking) must be justified and documented, and approved by the MICCAI Challenges Team (miccai-challenges-2026@dkfz-heidelberg.de).
  • Authors assign to the MICCAI Society the right to distribute challenge materials (e.g., agenda, design document) to MICCAI members and conference attendees, independently of the copyright ownership planned by organizers.
  • All organizers and speakers participating in MICCAI 2026 challenges are expected to register for the event (unless a waiver has been requested and granted).

Organizer Responsibilities

Accepted challenge organizers are responsible for:

  • Providing high-quality datasets and ground truth
  • Sharing the annotation protocol
  • Defining clear evaluation metrics and ranking procedures
  • Managing the challenge website and submission system
  • Evaluating submissions and determining winners
  • Organizing a MICCAI 2026 session to present and discuss results

Challenge application two years in advance

Organizing a challenge may be time-consuming, especially when large-scale data annotation is necessary. To address the traditionally tight schedule between MICCAI challenge acceptance and organization we offer an early review of MICCAI 2027 challenge proposals this year. Organizers interested in organizing a challenge in 2027 may use this year's submission system and thus receive an early acceptance that leaves time for careful preparation of the challenge.

Proceedings

Publishing a proceedings volume is optional and at the discretion of each workshop's organizers. At a minimum, organizers must make abstracts of all accepted presentations publicly available. Organizers who wish to publish MICCAI Springer LNCS proceedings should use OpenReview as the official submission and peer-review platform, to help ensure a rigorous and transparent review process. We will provide short tutorials and step-by-step instructions for creating the OpenReview submission page and configuring tracks.
