How does the risk of ionising radiation differ between X-ray imaging and ultrasound imaging?.
- A.X-rays use ionising radiation, ultrasound does not
- B.Ultrasound uses ionising radiation, X-rays do not
- C.Both use the same level of ionising radiation
- D.Neither uses ionising radiation
Model answer
What a good answer should say
- X-rays use ionising radiation, ultrasound does not
Explanation
Why this works
X-rays use ionising radiation, which can pose a risk to patients, particularly with repeated exposure. In contrast, ultrasound imaging does not use ionising radiation, making it safer for patients, especially in prenatal imaging.
This distinction is crucial when considering patient safety in imaging choices.
