Computed Tomography (CT) is a sensitive diagnostic tool that uses X-rays to take a series of two-dimensional cross-sectional images (‘slices’) around an axis. It has been in widespread use since the 1970s and is used to image many diseases and injuries.
Using X-rays does carry a small risk. However, to put this into context, a CT scan will deliver approximately the same amount of radiation you would absorb from your normal surroundings in about three years. Another way of looking at this is to say that the benefits of having a scan outweigh the risks associated with it.
Patients referred to Taranaki Radiology for a CT examination will have their scan performed on the CT scanner at Taranaki Base Hospital on one of our dedicated sessions.
