Fig. 9From: A medical device-grade T1 and ECV phantom for global T1 mapping quality assurance—the T1 Mapping and ECV Standardization in cardiovascular magnetic resonance (T1MES) programShort-term reproducibility. Short-term reproducibility (three runs) at the NIST laboratory (Test 1 in methods) for phantom T1values in six loose tubes (top left insert) from a final E-model phantom showing CoV of 1 % or less. Tube B with the longest T1|T2 showed the greatest variability between reads. CoV = coefficient of variationBack to article page
