Magnetic Resonance Imaging (MRI) Ofl Volunteers

Recruiting

• Conditions: Patients; Healthy Volunteers
• Interventions: Procedure: MRI

• Registration Number: NCT00001711
• Lead Sponsor: National Institutes of Health Clinical Center (CC)

Brief Summary

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.

Detailed Description

Technical evaluation of magnetic resonance imaging and spectroscopy will be performed on subjects who are eligible and willing to volunteer to have a research MRI performed. These studies may involve the administration of commercially available MR contrast media. Some scans may require inhaled carbogen (95% oxygen and 5% carbon dioxide) and hyperoxia (100% oxygen) 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.
