What is the consequence of using a tracer with an inappropriate half-life in medical imaging?.
- A.Increased clarity of the images produced
- B.Potential harm to the patient from excessive radiation
- C.Improved diagnostic accuracy
- D.Reduced need for follow-up imaging
Model answer
What a good answer should say
- Potential harm to the patient from excessive radiation
Explanation
Why this works
The cause is the inappropriate choice of half-life for the tracer. The mechanism is that if the half-life is too long, the tracer may expose the patient to unnecessary radiation for an extended period.
The effect is that this can lead to increased health risks. The consequence is that patient safety is compromised, potentially leading to long-term health issues.
