Synopsis

Keywords: Myocardium, Myocardium, Susceptibility-weighted Imaging

Diagnosis of intramyocardial hemorrhage (IMH) in ST-segment elevation myocardial infarction (STEMI) patients following reperfusion treatment is critical for determining prognosis. This study investigated the feasibility of susceptibility-weighted imaging (SWI) to detect IMH in STEMI patients that underwent reperfusion therapy by comparing the diagnostic performance and image quality with T1/T2 mapping. SWI showed excellent diagnostic performance in detecting IMH among STEMI patients that underwent reperfusion treatment and was comparable with T1/T2 mapping. SWI is a sensitive technique to accurately diagnose IMH in STEMI patients following reperfusion treatment.
