Short-term reproducibility of T₂ at 1.5 T (left) and 3 T (right) acquired using T₂ mapping bSSFP repeated 3 times in each of the final prototypes #Ci (at a temperature of 22°) (n = 1) and #Cii (at 21°) (n = 1) manufactured months apart, from independent stock solutions. All these scans were performed on the same day with independent placement of phantom and shims. Coefficients of variation (CoV) of T₂ are shown per tube and were all < 1% in the absence of temperature correction. CoV for T₁ using 3 MOLLI repeats are not shown here but were also < 1% for both prototypes (1.5 T range: 0.13–0.94%; 3 T range: 0.03–0.38%)
