ADetecting a tumour in tissue
BDetecting movement of ions
CDetecting breaks in a bone
DDetecting a stroke in a brain
Answer & Solution
Correct answer: C. Detecting breaks in a bone
1. MRI produces detailed images of soft tissue with none of the hazards of x rays.
2. It is nevertheless less effective than x rays for detecting breaks in bone.
3. It is also less effective for imaging breast tissue.
4. So the two tools complement each other rather than one replacing the other.
5. Tumours, strokes and the movement of ions across membranes are all cases where MRI does well.
