Text: A perfusion defect was detected in all 30 acute MPI studies ; in 7/10 patients (70 %) injected at 15 min ; in 11/30 patients (37 %) injected at 1, 2, or 3 h ; and in 7/37 patients (19 %) injected at 24 to 48 h. Perfusion scores were 13. 0 + / - 9. 2 on acute MPI, 5. 1 + / - 2. 8 at 15 min (p < 0. 001 vs. acute MPI) ; 2. 6 + / - 3. 0 at 1, 2, and 3 h (p < 0. 001 vs. acute MPI) ; and 1. 3 + / - 2. 4 at 24 to 48 h (p < 0. 001 vs. acute MPI ; p < 0. 03 vs. delayed MPI).
