Comparative Study
Simultaneous cardiac output and regional myocardial perfusion determination with PET and nitrogen 13 ammonia.
The purpose of this study was to evaluate the possibility of measuring cardiac output during positron emission tomography (PET) examination of myocardial perfusion with nitrogen 13 ammonia. ⋯ Cardiac output determination with N-13 ammonia and PET appears to be both accurate and precise and can be performed simultaneously with measurement of myocardial perfusion.
