Question 4 of 10

4. In a transverse section of the CT of the brain, a ring of the cranium is seen which is absent or not so prominent in MRI. What is this reason?

MRI images soft tissues so it does not image the cranium properly. Thus, the cranial ring is more prominent in CT than in MRI

Cranial ring is made of bones which do not have water, so it cannot give an MRI

The cranium is negated out while imaging

The EM waves received by MRI does not have sufficient magnetic strength to view the bones
