Brief Summary
Magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS) are diagnostic tests that allow researchers to look at different chemical properties of tissue. Magnetic resonance imaging and spectroscopy studies can be used to gather or evaluate information about various aspects of patient s bodies or to monitor changes in the biochemistry and physiology of patient s bodies. Unlike other diagnostic techniques (CT scan and PET scan) MRI and MRS do not use ionizing radiation. Some studies have shown that MRI is more effective at distinguishing normal parts of the anatomy from abnormal anatomy, especially in the brain. MRI has become the diagnostic test of choice for evaluating patient with multiple sclerosis. The purpose of this study is to evaluate normal volunteers and patients with a variety of diseases with magnetic resonance imaging. Researchers will attempt different magnetic resonance imaging methods and techniques as well as different levels of magnetic strength.

Patients undergoing MRI in the Clinical Center
All patients who, by virtue of the NIH protocol in which they are enrolled, who qualify for MRI will be eligible for participation in this protocol.
Eligibility Criteria
All patients who by virtue of the NIH protocol in which they are enrolled who qualify for MRI in the Clinical Center, are eligible to participate if (1) Stable for MRI (2) Able to understand the consent so that consent/assent can be obtained
You may qualify if:
- All patients undergoing MRI in the Clinical Center.
- Patients must be able to provide informed consents.
You may not qualify if:
- Contraindications to MRI.
- Inability to understand consent form or consent process and the absence of a suitable guardian.
- Adults who are or may not be able to consent
- Patients in whom the scan must be performed quickly, i.e. those patients under anesthesia, anxious patients, those requiring emergency medical care, or others in which it is deemed inappropriate to prolong a study.
- Refusal to Participate.
- Pregnant women and fetuses
- Neonates
