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.
MRI is a constantly evolving imaging modality and MR. Pulse sequences are often modified to improve their performance. However, many of these changes have not yet been approved by the FDA and therefore, are not considered standard of care. Some of these sequences require the use of new types of imaging coils, which are also investigational. The major purpose of this protocol is to inform patients undergoing MR scans in the Clinical Center that they may undergo scans that are not FDA approved and to get the patient's consent for this. This is not a formal research study since specific disease entities and specific pulse sequences are not studied in a systematic way. Rather, the purpose is to give NIH patients access to gradual improvements in MR technology that would otherwise not be available to them. A secondary purpose is to inform patients about the risks of MRI and gadolinium chelates which are commonly employed in MRI.

Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.
Governmental guidelines and objectives pertaining to public food supply and nutrition including recommendations for healthy diet and changes in food habits to ensure healthy diet.
Surgical reinnervation of a denervated peripheral target using a healthy donor nerve and/or its proximal stump. The direct connection is usually made to a healthy postlesional distal portion of a non-functioning nerve or implanted directly into denervated muscle or insensitive skin. Nerve sprouts will grow from the transferred nerve into the denervated elements and establish contact between them and the neurons that formerly controlled another area.
Process of evaluating the health of a patient and determining if they are healthy enough for surgery.
Dietary patterns which have been found to be important in reducing disease risk.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
