What is the shelf-life of Fluorine-18 (F-18)?

• A. 110 minutes
• B. 6 hours
• C. 13.3 hours
• D. 78 hours

Answer: (A)

Fluorine-18 (F-18) has a half-life of approximately 110 minutes, which is essential to understand in the context of nuclear medicine, particularly for positron emission tomography (PET) imaging. The half-life refers to the time it takes for half of the radioactive substance to decay. In practical terms, this means that F-18 is useful for imaging purposes because it decays quickly enough to be relevant for diagnostic procedures, yet not so fast that it cannot be produced, transported, and utilized effectively in a clinical setting. When performing procedures that utilize F-18, technicians must keep the short half-life in mind, as it dictates how quickly the radioactive tracer must be used after production. This characteristic ensures that the highest quality images are obtained while minimizing the patient's radiation exposure. Understanding the half-life also plays a crucial role in the planning and timing of radiopharmaceuticals administration, as well as in patient scheduling for PET scans. In summary, the shelf-life of Fluorine-18 being around 110 minutes makes it a suitable choice for a variety of nuclear medicine applications while maximizing diagnostic accuracy and patient safety.
