Which imaging technique typically involves a higher radiation dose?.
- A.CT imaging.
- B.Plain X-ray imaging.
- C.Both techniques have the same dose.
- D.Neither technique involves radiation.
Model answer
What a good answer should say
- CT imaging.
Explanation
Why this works
CT imaging typically involves a higher radiation dose compared to plain X-ray imaging due to the multiple X-ray images taken from various angles to create detailed cross-sectional views. While both techniques use ionizing radiation, the cumulative exposure from CT scans is generally greater, making it important to consider the necessity of the scan against the potential risks of radiation exposure.
