From: Left ventricular T1-mapping in diastole versus systole in patients with mitral regurgitation

Examples showing how goodness-of-fit R2 values were generated in diastole (A + C) and systole (B + D) by in-house software. Graphs (C + D) demonstrate the greater difference in measured T1 values to the fitted curve in diastole (C) compared to systole (D).
