Brain Oxygen Utilization: Methods Validation

Purpose

This study is being done to test a new method for measuring brain oxygen use (oxygen metabolism) that will be faster, cheaper and more widely available than the older method. The new method uses MRI (Magnetic resonance imaging) that developed by a research group in Johns Hopkins University. The older method uses PET (positron emission tomography), which has been recognized as the gold standard for over 30 years. This study will compare the two methods in healthy, normal people, to test whether they give the same values.
