Healthy controls are represented by filled circles, diabetic adults are represented by empty circles. (A) The average global left ventricular native-T1 time was not correlated with ECV (Pearson’s ρ = 0.06, P = 0.73) derived from pre- and post-contrast T1 times. (B) Similarly, the average left ventricular magnetization transfer ratio (MTR) was not correlated with ECV values (Pearson’s ρ = 0.15, P = 0.38). (C) In contrast, a significant correlation was observed between native-T1 and the left ventricular MVR (Pearson’s ρ = 0.36, P = 0.025). (D) No correlation was observed between the magnetization transfer ratio and the MVR (Pearson’s ρ = 0.07, P = 0.67).
