7 Tesla MRI is a new magnetic field strength that has become available at Penn for cardiovascular MRI. This new scanner has potential to improve assessment of cardiovascular disease due to its increased signal-to-noise ratio, higher spatial resolution, and response to magnetic properties of tissue at high field. The purpose of this study is to assess the feasibility of 7 T CMR. Secondly, we wish to investigate its use, to improve clinical and research MRI. Altogether, 7 T may permit better clinical diagnosis of cardiomyopathy.

Inclusion Criteria:

• Subjects between the ages of 20-70 years old

Exclusion Criteria:

• Advanced renal disease (estimated GFR rate < 30 mL/min) or hypersensitivity to gadolinium contrast agent.
• Presence of cardiac pacemaker or implanted cardioverter defibrillator
• Pregnancy
• Inability to provide informed consent
• Other contraindications to MRI (such as claustrophobia)

The eligible population are cardiomyopathy patients and normal volunteers.
