Native myocardial T1 images (top row), quantitative extracellular volume (ECV) fraction images (middle row), and late gadolinium enhancement (LGE) images (bottom row) in a 33-year-old man with apical hypertrophic cardiomyopathy. Patchy intramyocardial areas of elevated T1 and ECV were mainly in apex (arrows). These findings suggest increased extracellular matrix in hypertrophied areas of myocardium. No obvious LGE was observed on conventional LGE images.
