Healthy Clinical Trial
Official title:
Technical Evaluation of Cardiovascular Magnetic Resonance Imaging and Spectroscopy
Magnetic resonance imaging (MRI) and spectroscopy are diagnostic tools that create high
quality images of the human body without the use of X-ray (radiation). MRI uses different
levels of magnetic fields to create images of the body and organs. Occasionally, researchers
will give patients undergoing a MRI an injection of a contrast substance. The contrast
substance works by brightening areas of the magnetic resonance image.
In this study researchers plan to use magnetic resonance imaging with contrast substances and
exercise on normal volunteers in order to evaluate different aspects of its performance.
Information gathered from this study may be used to develop more specific research studies
involving MRI....
Technical evaluation of magnetic resonance imaging and spectroscopy will be performed on normal volunteers. These studies will be conducted in the NIH MRI systems located in Suburban Hospital in Bethesda, Maryland. These studies may involve the intravenous administration of commercially available MR contrast media and exercise. 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. ;
