CT scans and X-rays are diagnostic tests that carry health risks associated with ionizing radiations.
Ionizing radiation, such as X-rays and gamma rays, has enough energy to remove tightly bound electrons from atoms, creating ions. This process can damage DNA in cells, potentially leading to an increased risk of cancer over time, especially with repeated exposure. CT scans use multiple X-ray images.
MRI scans use strong magnetic fields and radio waves, which are non-ionizing forms of radiation and do not cause DNA damage in the same way as X-rays. Ultrasonography uses sound waves, also a non-ionizing form of energy. Medical professionals carefully weigh the diagnostic benefits of procedures involving ionizing radiation against the potential risks.
