Cardiac PET

Summary
Cardiac PET (or cardiac positron emission tomography) is a form of diagnostic imaging in which the presence of heart disease is evaluated using a PET scanner. Intravenous injection of a radiotracer is performed as part of the scan. Commonly used radiotracers are Rubidium-82, Nitrogen-13 ammonia and Oxygen-15 water. Uses Cardiac PET-CT scan can assess blood flow, metabolism, inflammation, innervation, and receptor density accurately. Besides, it is also useful to detect heart conditions such as coronary artery disease, cardiac amyloidosis, and cardiac sarcoidosis. Radiopharmaceuticals Rubidium-82 is produced from the decay of Strontium-82 through electron capture in a generator. It is used to access the blood vessels supplying the heart. Strontium-82 has a half-life of 25.5 days while Rubidium-82 has a half-life of 76 seconds. Heart muscles can take up Rubidium-82 efficiently through sodium–potassium pump. Compared with Technetium-99m, Rubidium-82 has higher uptake b
