Myocardial Perfusion Imaging by 15O-H2O PET/CT

Study Overview
=================
Brief Summary
-----------------
The trial will include 2500 patients with evident or suspected ischemic heart disease refered to Department of Nuclear Medicine & PET Centre, Aarhus University Hospital, for perfusion imaging by 15O-H2O PET/CT scan of the heart during rest and stress. The patients will undergo the clinical scan as normal. Data from the scans will be used to determine reference values of the examination. Follow up will be done for up to 10 years in regards to major cardiovascular events in order to determine the prognostic value of the scan.
