During a CT scan, the patient lies on a motorized table that slides through a circular opening of the CT scanner. The scanner rotates around the patient, taking multiple X-ray images from different angles. These images are then processed by a computer to create cross-sectional views.
In some cases, a contrast material may be used to enhance the visibility of certain structures. This can be administered orally, intravenously, or rectally depending on the area being examined.
