MRI images displaying the 4-chamber view (A) and mid- ventricular short-axis slice (B) during diastole, global longitudinal strain assessment (GLS) (C), and stress myocardial perfusion map in mid-ventricular short-axis slice (D). Top row images were from a 59-year-old male with type 2 diabetes (T2D), BMI of 40 kg/m²; left ventricular mass (LVM) 146 g, left ventricular end-diastolic volume (LVEDV) 122 mL, left ventricular mass to volume ratio (LVM/V) 1.2 g/mL, GLS 13.0%, stress myocardial blood flow (MBF) 1.2 mL/min/g, rest MBF 0.6 mL/min/g, and myocardial perfusion reserve (MPR) 2.0. The bottom row images were from a 64-year-old male non-diabetic control, BMI of 32 kg/m²; LVM 179 g, LVEDV 223 mL, LVM/V 0.8 g/mL, GLS 15.3%, stress MBF 2.2 mL/min/g, rest MBF 0.6 mL/min/g, and MPR 3.7. Note for GLS with darker blue indicates greater shortening and higher strain
