The increasing use of CT brings with it concerns about the ionizing radiation exposure involved and the associated risks, especially the risk of cancer.

As a precaution, it is presumed that even low doses entail risks, in proportion to the dose.

Developments in CT technology such as automatic exposure control and tailored scan protocols make it possible to reduce the radiation dose, sometimes considerably.

It is important to be critical about the indication for the test. The diagnostic advantage should outweigh the possible long-term risks.

Children are at greater risk; in their case there should be a strong indication for CT and the dose should be low.
