Question

question 1 of 10
which of these is an advantage of an ultrasound over an x - ray?
a. it can produce images of soft tissue.
b. its equipment needs its own room.
c. it does not require training.
d. it uses more radiation.

Explanation:

To determine the advantage of ultrasound over X - ray, we analyze each option:

• Option A: Ultrasound is good at imaging soft tissues (like in prenatal scans to see the fetus, or for looking at organs like the liver, kidneys). X - rays are better at imaging bones and dense structures and are less effective at visualizing soft tissues clearly. So this is a valid advantage.
• Option B: Needing its own room for equipment is not an advantage; it's a drawback in terms of space requirements.
• Option C: Using ultrasound requires training (to operate the machine and interpret the images), so this is incorrect.
• Option D: Ultrasound uses no ionizing radiation, while X - rays do. Saying it uses more radiation is wrong.

Answer:

A. It can produce images of soft tissue.
