CT scans use X-rays, not magnetic fields, to create detailed cross-sectional images of the body. They involve radiation exposure.
This statement is correct. While CT scans use X-rays, the amount of radiation used in modern CT machines is relatively low and considered safe. The benefits of the diagnostic information obtained from the scan usually outweigh the risks associated with the small amount of radiation exposure.
The speed of the scan does not impact the radiation exposure. The amount of radiation used in a CT scan remains the same regardless of the scan duration.
CT scans use X-rays, not sound waves. Sound waves are used in ultrasound imaging, not in CT scans.
Choice A reason:
