From: Knee dGEMRIC at 7 T: comparison against 1.5 T and evaluation of T1-mapping methods
Scatter (a) and Bland-Altman plot (b) comparing IR T1 values at 7 T using an adapted TI sampling with an additional longer TI (7 TIs) and the IR TI sampling pattern with 6 TIs. In a) the line of identity is shown in solid black. In b) the average bias and limits of agreement are shown in solid and dashed black lines, respectively. The T1 values using 6 TIs were underestimated compared to using 7 TIs
