X-Nuclei Meeting 2025

Dear Colleagues and X-Nuclei Community,

We are delighted to welcome you to the 2025 X-Nuclei User Meeting, which will take place in the vibrant city of Marseille, France, on October 8th. This year’s meeting will bring together researchers, clinicians, and spectroscopy/imaging specialists to share the latest developments in X-nuclei MR, foster collaboration, and exchange ideas in a friendly and stimulating environment.

On October 7th, the day before the meeting, CRMBM Marseille will celebrate its 40th anniversary with an afternoon scientific session (in English). The program and registration are available online.

Please also note that the ESMRMB 2025 Annual Meeting will be held in Marseille from October 9–11, with pre-conference events scheduled for October 8, coinciding with our X-Nuclei User Meeting. This will offer an excellent opportunity for participants to combine both events during their stay in Marseille.

We look forward to insightful discussions, new connections, and another step forward for our growing community.

Warm regards,
Shailesh Appukuttan, Giulia Borromeo, Adil Maarouf & Wafaa Zaaraoui
