Regional analysis that highlights peak myocardial blood flow (MBF) differences between the
septum and lateral wall depending on the delayed enhancement (DE) status.

Patients with hypertrophic cardiomyopathy and delayed enhancement (DE)–positive cardiac
magnetic resonance (n=35) were divided into tertiles based on the extent of DE in the left
ventricular (LV).

Matching cardiac magnetic resonance (CMR) and positron emission tomography (PET)
abnormalities (red arrows) of 2 patients with hypertrophic cardiomyopathy that demonstrate
concordant delayed enhancement (DE) on CMR and reversible (stress only) regional myocardial
perfusion PET abnormalities in the mid anteroseptal wall (patient A) and septum (patient B).
