We’re excited to share that the **validation dataset for MRIxFields2026** is now live and ready for download: 🔗 [https://www.synapse.org/Synapse:syn72060672/files/](https://www.synapse.org/Synapse:syn72060672/files/) This marks an important step as we move from data exploration to **model validation and benchmarking across fields (0.1T–7T)**. 📊 **How to participate?** Validation results should be submitted through our upcoming **leaderboard system**. 👉 Submission instructions: [https://github.com/MRIxFields/MRIxFields2026?tab=readme-ov-file](https://github.com/MRIxFields/MRIxFields2026?tab=readme-ov-file) ⏳ The **leaderboard will officially launch in early May** — stay tuned! We’re looking forward to seeing how the community tackles: * cross-field harmonization * ultra-low-field enhancement * controllable MRI generation 💡 Whether you're working on generative models, domain generalization, or medical imaging AI — this is a unique opportunity to test your methods on a truly **multi-field, multi-center dataset**. Thanks again to everyone who has joined the challenge — exciting results ahead!
