Late gadolinium enhancement imaging of “scar” and fibrosis is a vital tool in the assessment of a broad spectrum of cardiovascular diseases. In particular, late gadolinium enhancement characterization of myocardial infarction and cardiomyopathy has demonstrated its utility in predicting future adverse cardiovascular events. This presentation reviews the basics of late gadolinium enhancement imaging, touching upon technical challenges and simple solutions that may mitigate image artifact. Additionally, examples of the common clinical applications are discussed.
