PET-POSITRON EMISSION TOMOGRAPHY

Physics

PET-POSITRON EMISSION TOMOGRAPHY

1. PET is a tomographic radionuclide imaging technique used in oncology, cardiology, neurology.

2. Relies on the detection of the pair of gamma-ray photons resulting from the annihilation of a positron and an electron.

3. PET radiopharmaceuticals therefore decay by positron emission (BETA PLUS DECAY).

4. Signal is determined by the activity of radiopharmaceutical in a voxel of tissue.

5. Most commonly used are 18 F, 68 Ga.
