A collaborative reproducibility challenge was launched to explore if an imaging protocol independently-implemented at multiple centers can reliably measure T1 using inversion recovery in a standardized quantitative MRI phantom (ISMRM/NIST). A total of 19 submissions were accepted, totalling 41 phantom T1 mapping datasets. Errors relative to the temperature-corrected reference T1 values were under 10% for the range of values expected in the human brain in vivo. All submitted phantom data, code, pipelines, and scripts were shared on open platforms.
