Uses
1 INDICATIONS AND USAGE Ammonia N 13 Injection is indicated for diagnostic Positron Emission Tomography (PET) imaging of the myocardium under rest or pharmacologic stress conditions to evaluate myocardial perfusion in patients with suspected or existing coronary artery disease. 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 ( 1 ).
Dosage
2 DOSAGE AND ADMINISTRATION Rest Imaging Study ( 2.1 ): Aseptically withdraw Ammonia N 13 Injection from its container and administer 10-20 mCi (0.368 – 0.736 GBq) as a bolus through a catheter inserted into a large peripheral vein. Start imaging 3 minutes after the injection and acquire images for a total of 10-20 minutes. Stress Imaging Study ( 2.2 ): If a rest imaging study is performed, begin the stress imaging study 40 minutes or more after the first Ammonia N13 injection to allow sufficient isotope decay. Administer a pharmacologic stress-inducing drug in accordance with its labeling.
