FIGURE 5. Bar graph shows sensitivities and specificities of ²⁰¹Tl, DE, and sequential strategies (strategy 1: ²⁰¹Tl was initial test, and DE was additional test; strategy 2: DE was initial test, and ²⁰¹Tl was additional test) for predicting improved LVEF after revascularization. Sens = sensitivity; spec = specificity; strat = strategy.
