Welcome to the first MRM Highlights Journal Club webinar, recorded on June 11th, 2024. In this session, we discuss the paper titled "Repeat it without me: Crowdsourcing the T1 mapping common ground via the ISMRM reproducibility challenge" by Mathieu Boudreau, Agah Karakuzu, and colleagues, published in Magnetic Resonance in Medicine.
