Abstract

Myocardial viability is a fundamental question in the clinical and therapeutic decision making process. Contrast-enhanced MRI can distinguish between viable and necrotic myocardium in non-invasive manner and with excellent definition of endocardial and epicardial borders. Aim of this study is to propose a software methodology that allows to assess the global, transmural and intramural extent of myocardial necrosis providing both bull-eyes and 3D representation of contrast delayed enhanced area in MRI cardiac images.
