Comprehensive infarct detection protocol. After scout and localizer images were obtained, contrast-enhanced cine imaging (retrospective ECG gating with tube current modulation) was obtained (this was performed during adenosine stress, but myocardial stress perfusion images were not used in the present analysis). Approximately 5 minutes later, prospectively ECG-triggered rest perfusion images were obtained during a second contrast bolus infusion. Approximately 10–15 minutes later, prospectively ECG-triggered delayed images were obtained, without additional contrast for myocardial delayed enhancement imaging.
