Previous studies suggested that the periinfarct zone in acute myocardial infarction may provide the important prognostic information and serve as a therapeutic target. It is widely known that the hyperintense area in T2-weighted imaging closely matched the periinfarct zone. However, T2-weighted image is sometimes degraded by motion artifact and arrhythmia. In this study, we demonstrate that the early phase in late gadolinium enhancement (at the time of 2 minutes after gadolinium administration) can clearly visualize the periinfarct zone similar to or better than T2 map and offer robust diagnostic image quality compared to T2-weighted image.
