Research Summary:

The focus of Dr. Zia’s research is delineating myocardial tissue injury using cardiac magnetic resonance imaging post acute myocardial infarction. Cardiac magnetic resonance has gained clinical importance in the noninvasive assessment of myocardial injury post acute myocardial infarction. Myocardial edema, hemorrhage and microvascular obstruction are important parameters of microvascular injury implicated in the remodeling process.

His imaging group has developed and characterized the evolution of myocardial edema and hemorrhage using quantitative T2 and T2* mapping techniques postacute myocardial infarction. This knowledge could help evaluate potential treatment strategies and allow for quantitative imaging parameters to be used as surrogate markers of important clinical outcomes.
