Myocardial Perfusion Magnetic Resonance Imaging Using Regadenoson

Summary

This is a pilot study to determine whether the drug regadenoson can be used during magnetic resonance imaging to assess regions of poor blood flow to the heart. The hypothesis of this study is that a single injection of regadenoson could be used instead of a standard adenosine infusion to produce coronary vasodilatation and demonstrate myocardial ischemia during first-pass perfusion cardiac MRI.
