Figure 1

(A) Polot of RVFW stiffness versus pre-contrast T1 at end-sysole (ES) and end-diastole (ED). Excellent linear correlation was found between the variables at ED (R² = 0.96) and modest correlation at ES (R² = 0.47). (B) Plot of RVFW stiffness versus extracellular volume fraction (ECV). Good linear correlation was observed between variables both at ED (R² = 0.70) and ES (R² = 0.95). (C) Plot of RVFW stiffness versus T2 relaxation time. No significant or consistent correlation was found between the variables. A positive linear correlation was observed at ED (R² = 0.26) and inverse linear correlation at ES (R² = 0.49).
