When using 2-[¹⁸F] fluoro-2-deoxy-D-glucose (FDG)uptake by tumor cells to detect cancerous masses, fluorescein 18 decays releasing __________. This in turn reacts with __________ and releases pairs of _________________ which are ultimately detected by the diagnostic scanner.

Question

Quizplus · Accepted Answer

Fluorescein 18 decays and releases a positron, which reacts with an electron and produces a pair of photons. This process is known as positron emission, and it is the principle behind positron emission tomography (PET) scans used to detect cancerous masses. Therefore, the correct option is B, which states that fluorescein 18 releases a positron and reacts with an electron to produce photons.
