Repeat it without me: Crowdsourcing the T₁ mapping common ground via the ISMRM reproducibility challenge

Abstract

The T₁ intersubmission variability was twice as high as the intrasubmission variability in both phantoms and human brains, indicating that the acquisition details in the original paper were insufficient to reproduce a quantitative MRI protocol. This study reports the inherent uncertainty in T₁ measures across independent research groups, bringing us one step closer to a practical clinical baseline of T₁ variations in vivo.
