Fig. 1From: Extracellular volume fraction measurements derived from the longitudinal relaxation of blood-based synthetic hematocrit may lead to clinical errors in 3 T cardiovascular magnetic resonanceCorrelation between blood 1/T1 and hematocrit (HCT) and robustness of R2 in the derivation group. Left panel showing the linear regression line between the HCT and 1/T1blood native with R2 (p and regression equations shown in the graph). Right panel shows the R2 distribution based on 100-times bootstrap correlation analysisBack to article page
