Why is it important for a tracer's half-life to be longer than the imaging procedure duration?.
- A.To ensure the tracer can be reused
- B.To allow for the complete decay of the tracer
- C.To ensure sufficient tracer remains for accurate imaging
- D.To minimize the cost of the procedure
Model answer
What a good answer should say
- To ensure sufficient tracer remains for accurate imaging
Explanation
Why this works
The cause is the duration of the imaging procedure. The mechanism is that a longer half-life allows the tracer to remain active and detectable throughout the imaging process.
The effect is that the images produced will be of high quality and informative. The consequence is that this leads to better diagnostic outcomes for patients.
