What is the half-life of F18 FDG?

The half-life of F-18 fluorodeoxyglucose (FDG) is approximately 110 minutes. However, the closest answer to this value in the provided options is 100 minutes. The significance of knowing the half-life of F-18 FDG lies in its application in positron emission tomography (PET) imaging. The relatively short half-life allows for rapid imaging after injection, minimizing radiation exposure while still providing effective imaging for diagnosing conditions such as cancer.

The half-life determines how long the radioisotope remains effective for imaging purposes, impacting the timing of scans in clinical settings. Understanding this time frame is crucial for radiopharmacists and healthcare providers to ensure optimal imaging outcomes while managing doses and safety for patients.
