How does the strength of the magnetic field affect MRI signal detection?.
- A.It has no effect on the signal detection.
- B.A stronger magnetic field increases signal clarity.
- C.A weaker magnetic field improves signal detection.
- D.It only affects the speed of the imaging process.
Model answer
What a good answer should say
- A stronger magnetic field increases signal clarity.
Explanation
Why this works
A stronger magnetic field enhances the alignment of hydrogen nuclei, leading to clearer and more detailed signals during MRI, which improves image quality.
