Fig. 3From: Knee dGEMRIC at 7 T: comparison against 1.5 T and evaluation of T1-mapping methodsA scatter plot of IR T1s at 7 T against IR T1 at 1.5 T for healthy (grey circles) and patient subjects (red triangles) demonstrating the strong correlation between dGEMRIC at the two field strengths (Pearson correlation coefficient = 0.80). The linear regression with slope = 1.95 (1.61–2.29) and intercept = − 71.9 (− 248–104) is shown in solid blackBack to article page
