What is the half-life of n13?
Nitrogen N 13 decays by emitting positron to Carbon C 13 (stable) and has a physical half-life of 9.96 minutes.
How is nitrogen-13 used in PET?
Nitrogen-13 (13N) is a radioisotope of nitrogen used in positron emission tomography (PET). It has a half-life of a little under ten minutes, so it must be made at the PET site. A cyclotron may be used for this purpose. Nitrogen-13 is used to tag ammonia molecules for PET myocardial perfusion imaging.
What is a CV MPI PET?
WHAT IS A CARDIAC PET MPI EXAM? A cardiac positron emission tomography (PET) myocardial perfusion imaging (MPI) exam is used by doctors to evaluate the health of your heart by measuring the blood flow that it receives. People who receive this exam may have symptoms and/or risk factors for heart disease.
What is the half-life of ammonia?
Ammonia (N-13) is administered intravenously, at a dose of 10-20 mCi (370-740 Mbq) in adults; its physical half-life is 10 minutes.
What is N13 blacklist?
N-13 is not a what but a who. In Episode 2, fans learn that the N stands for the word neopoznanny, which is the Russian word for unidentified. The 13 signifies the 13 packets of intel that the operative stole from Lubyanka Square in 1990.
Is N-13 stable?
It has been suggested that Nitrogen-13 be merged into this article. (Discuss) Natural nitrogen (7N) consists of two stable isotopes: the vast majority (99.6%) of naturally occurring nitrogen is nitrogen-14, with the remainder being nitrogen-15….List of isotopes.

What is ammonia N 13 used for?
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.
Is N 13 stable?
What is the difference between PET MPI and SPECT MPI?
PET myocardial perfusion has a 95% sensitivity and 95% specificity for detecting coronary artery disease, while SPECT myocardial perfusion has an 87% sensitivity and 73% specificity for detection.
What is the purpose of nitrogen-13?
Nitrogen-13 is a radioisotope used in positron emission tomography (PET). It has a half-life of 9.9 minutes. N is mainly used to tag ammonia molecules for PET myocardial perfusion imaging but it can also be used for brain and liver imaging.
What is the name for N13?
Ammonia n-13 is a Radioactive Diagnostic Agent. The mechanism of action of ammonia n-13 is as a Radiopharmaceutical Activity. Ammonia-(13)N is a (13)N-modified compound that is ammonia that has a (13)N isotope as the nitrogen atom. (13)N decays with a half-life of ten minutes to (13)C, emitting a positron.
