Serial PET distinguishes regional flows post-MI; leaves open its utility for viability assessment or therapy guidance.
Can serial PET imaging quantify differences in regional blood flow and metabolism in hypoperfused infarct regions in patients with recent myocardial infarction?
PET imaging can quantify regional blood flow and substrate metabolism in postinfarction patients, revealing preserved oxidative metabolism in mismatch regions likely due to increased oxygen extraction.
