Many translational MR biomarkers derive from measurements of the longitudinal relaxation rate R1, but evidence for between-site reproducibility of R1 in small-animal MRI is lacking. The objective of this study was to assess R1 repeatability and multi-site reproducibility in phantoms for preclinical MRI.
