Question

which of these is an advantage of a ct scan over an mri? a. it produces a two - dimensional image. b. it improves the ability to make a diagnosis. c. its equipment is more portable. d. it uses no radiation.

Explanation:

CT - scan equipment is more portable compared to MRI machines. MRI machines are large and require special infrastructure for installation due to their strong magnetic fields and cryogenic systems. CT - scans can sometimes be more mobile, for example, in some mobile medical units. Option A is incorrect as both can produce 2 - D and 3 - D images. Option B is wrong because the diagnostic ability depends on the condition being evaluated and both have their own strengths. Option D is incorrect as CT - scans use X - ray radiation.

Answer:

C. Its equipment is more portable.
