Representative cases showed myocardial perfusion function and longitudinal peak diastolic strain rate (PDSR-L) in a control (top row), a patient with HbA1c < 7.0% (middle row), and a patient with HbA1c ≥ 7.0% (bottom row). First-pass myocardial perfusion MR images (A, E, and I) and signal intensity-time curves (B, F, and J) were obtained from the left mid-ventricular slices. PDSR-L was analyzed using Bull's-eye plots (D, H, and L) derived from long-axis cine images (C, G, and K). Max SI, maximum signal intensity; TTM, time to maximum signal intensity
