What is a key advantage of gamma camera imaging compared to MRI?.
- A.Gamma cameras provide real-time imaging.
- B.Gamma cameras can detect metabolic activity.
- C.Gamma cameras use non-ionising radiation.
- D.Gamma cameras have higher spatial resolution.
Model answer
What a good answer should say
- Gamma cameras can detect metabolic activity.
Explanation
Why this works
Gamma camera imaging uses radioactive tracers that emit gamma rays, allowing for the visualization of metabolic processes in the body. In contrast, MRI uses magnetic fields and radio waves to create images of soft tissues, which does not provide metabolic information.
Gamma cameras are particularly useful in diagnosing conditions like cancer, where metabolic activity is a key indicator.
