Less favorable CoVs (> 2%, see the “T₁ repeatability” section) are in italics. Post-GBCA tubes are not shown here as their data are reported separately in relation to post-GBCA sequences in Supplementary Table 6

sic = text is quoted exactly as it stands in the original, i.e., this is not a typo. Abbreviations as in Table 1

^aDenotes the T₁ mapping sequence|software combination with lowest overall CoV% for a given vendor where multiples exist

^bDenotes the number of different magnets submitting that particular sequence from which the average CoVs were derived

^cIn the absence of iterative/data dropping steps in map creation as per ShMOLLI

x̅ = average CoV across the 4 native tubes for a given sequence

x̅’ = where more than one sequence type was submitted, individual CoVs were then averaged to derive x̅’ CoV; while for single sequence submissions x̅’ CoV is from the global mean T₁ ± SD for that one sequence
