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.
