All CT scans involve exposure to radiation. In theory radiation can be harmful but there have never been any proven negative effects at the low doses used in diagnostic imaging.

Dr Jones & Partners has invested in up to date equipment in order to minimise radiation exposure to patients. We continuously monitor the radiation doses in our practice and they are almost always below the reference standards set by the national governing body, ARPANSA.

The radiation exposure from a CT scan will vary with the type of scan and the size of the patient. Everyone is exposed to radiation from natural sources everyday and in many cases the radiation dose from a CT scan would be equivalent to, or less than, the radiation from natural sources in a year.

It is also important to remember that the risk of missing an important finding is almost always going to be larger than the theoretical risk from radiation from a CT scan.
