FIGURE 7. Relationship between RV metabolic rate of glucose uptake and Tei index is shown in C. Characteristic short-axis slices from 18F-FDG PET images of 2 patients with different Tei indices are shown in A and B. Parameters for A vs. B: Tei index, 0.49 vs. 1.05; metabolic rate of glucose uptake, right, 11.75 vs. 31 µmol/100 g/min; metabolic rate of glucose uptake, left, 20.75 vs. 24.3 µmol/100 g/min; PAP, 39 vs. 55 mm Hg; PAR, 540 vs. 874 dyn x s x 10–5; stroke work, right, 20.5 vs. 34.7; stroke work, left, 54.4 vs. 55.5; New York Heart Association class, II vs. III; right heart failure, no vs. yes. (C) y = –3.3343 + 26.7048x; r = 0.78; P < 0.001. MR = metabolic rate of glucose uptake.
