Invited Lecture Session 1: Standardization in Parametric Mapping (2019)-Unmet Clinical Needs

Video Transcription

Video Summary

The speaker reviews parametric mapping in cardiac MRI, focusing on T1, T2, and T2* mapping as ways to characterize tissue without gadolinium contrast. Key uses include ischemia detection with stress T1 mapping, infarct sizing in chronic and acute MI, and diagnosis/risk assessment in non-ischemic cardiomyopathies such as hypertrophic cardiomyopathy, amyloidosis, Fabry disease, and myocarditis. T2 mapping helps identify edema and predict outcomes in myocarditis and amyloidosis, while T2* is crucial for iron overload and myocardial hemorrhage. A major theme is that values vary by scanner and must be standardized across sites.
