This paper evaluates the detection of mild coronary stenoses with 13N PET during pharmacologically induced vasodilation.

For Intravenous Use


Ammonia N 13 Injection is a radioactive diagnostic agent for Positron Emission Tomography (PET) indicated for diagnostic PET imaging of the myocardium under rest or pharmacologic stress conditions to evaluate myocardial perfusion in patients with suspected or existing coronary artery disease.


Radiation Risks: Ammonia N 13 Injection may increase the risk of cancer. Use the smallest dose necessary for imaging and ensure safe handling to protect the patient and health care worker.


Adverse Reactions: No adverse reactions have been reported for Ammonia N 13 Injection based on a review of the published literature, publicly available reference sources and adverse drug reaction reporting systems. However, the completeness of these sources is not known.
