Brief Summary:
To establish quantitative values of myocardial blood flow (MBF) in normal, healthy volunteers .

Condition or disease Intervention/treatment
Normal Healthy Volunteers Without Chronic Medical Conditions Procedure: cardiac PET stress test

Detailed Description:
We seek to establish quantitative values of myocardial blood flow in 20 normal, healthy volunteers using our existing 2D PET camera (Positron Attrius) and invasively validated software package (HeartSee) in order to 1) establish institutional values for which clinical patients can be compared to and 2) add to the collective data of the scientific community. Values to be measured will be resting myocardial blood flow (MBF), stress MBF and coronary flow reserve.

Group/Cohort Intervention/treatment
Normal volunteers
Normal, healthy volunteers with undergo cardiac PET stress testing.
Procedure: cardiac PET stress test
Volunteers will undergo cardiac PET stress testing
