Abstract

Introduction: Delayed contrast-enhanced magnetic resonance imaging (ceMRI) has been shown to identify areas of irreversible myocardial injury due to infarction (MI) in the acute, sub-acute and chronic phase of MI with high spatial resolution, allowing precise quantification of non-viable myocardium. However, the underlying mechanisms and factors influencing ceMRI image contrast remain to be fully defined.

Purpose: To investigate the influence of contrast agent (CA) dose and image acquisition timing after contrast injection on the quantitative analysis of the size of infarcted non-viable myocardium.

Methods: Patients with a history of chronic (older than 8 weeks) anterior myocardial infarction and typical ECG changes were included (n=9) and two MR scans were performed on consecutive days on a 1.5 Tesla Siemens Sonata system (Fig. ).
