Caution urged over CT scan radiation doses 

BBC News reports on a sharp rise in the number of CT scans being performed, exposing people to the potential health risks of radiation.

However, as The Daily Telegraph says, it is not possible to calculate the cancer risk due to exposure to CT scans because there is a lack of data.

These media stories follow the publication of a report by the Committee on Medical Aspects of Radiation in the Environment (COMARE).

COMARE has reviewed trends in the use of CT scans in the UK. The review weighs up the risk-benefit balance of using CT scans, and considers ways to obtain the best quality scan image while minimising the necessary radiation dose.

The COMARE report sets out good practice guidance, encouraging doctors to take a more “proactive approach” to protecting patients and reducing radiation doses.

The committee recommendations cover equipment and procedures already in place, but also note there are dose reduction features available on some of the newer CT scanning machines that should be considered when new equipment is purchased.
