What is a key difference in the information provided by PET scans compared to MRI scans?.
- A.PET scans show metabolic activity, MRI shows structure
- B.MRI shows metabolic activity, PET scans show structure
- C.Both provide the same type of information
- D.PET scans are less detailed than MRI scans
Model answer
What a good answer should say
- PET scans show metabolic activity, MRI shows structure
Explanation
Why this works
PET scans provide information about metabolic activity, which is useful for detecting cancer and monitoring treatment response. MRI, on the other hand, provides detailed structural images of tissues.
This difference is significant in clinical settings where understanding both structure and function is essential.
