Dobutamine magnetic resonance imaging with myocardial tagging quantitatively predicts improvement in regional function after revascularization.
Segmental contractile reserve measured by dobutamine magnetic resonance imaging quantitatively predicts improvement in end-systolic wall thickness after revascularization. Segments with end-systolic wall thickness <7 mm at rest do not demonstrate contractile reserve or improve after revascularization.
