i-CAT has a fast scan time, so there’s less chance of patient motion and has a lower radiation dose compared with conventional CT.
From a patient perspective, it is similar to having an OPG where you will be asked to sit with your chin resting on a small support shelf to provide accurate positioning. The scanner will move around your head and from this the processer will build and store a 3-dimensional image that the radiologist will review and assess.
The examination is painless.
