Magnetic resonance is an imaging technique that uses magnetic fields and radio waves to create images of the body. The technology used in magnetic resonance imaging continues to improve. Advancements in magnetic resonance imaging (MRI) requires researchers to study new techniques in normal volunteers in order to understand how to use them in patients with diseases.
In this study researchers plan to do a variety of diagnostic tests including magnetic resonance imaging on normal volunteers. The studies may involve injections of contrast media, substances injected into the blood of participant that improves the image created by the MRI scanner. The study is not expected to benefit the participants. However, information gathered from the study may be used to improve diagnostic techniques and develop new research studies.
Technical evaluation of magnetic resonance imaging and spectroscopy will be performed on normal volunteers. These studies may involve the intravenous administration of commercially available MR contrast media, glucagon or secretin, or an FDA approved microbubble contrast agent, Optison. Some scans may require gastrointestinal contrast such as water or dilute gadolinium or barium. We also use inhaled carbogen as a contrast media. The results will be used to evaluate the performance of various pulse sequences, gradient coils, and rf coils on human subjects and will provide essential ground work for specific patient protocols.

This study assesses how the nation's preeminent health promotion and disease prevention initiative, Healthy People, is utilized by key stakeholders.
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...
