Most of the patients get nervous when they see a CT machine because it seems very huge and massive. However, there is no reason for worry because a general CT examination is a relatively safer procedure. The CT scanner is a large machine that has a hole in the center. It is provided with a sliding patient table, which can move back and front. You will be asked to lie over the table and would be instructed by the radiographer regarding the procedure. Once he/she has made sure that you are familiar with the instructions, the examination would start. You may be required to remain still for a few minutes during the examination. However, this should not be for long. It usually takes about less than 10 to 15 minutes. You will be alone in the examination room. The radiologist would be seated in the adjacent room and you can communicate with them incase you feel any discomfort.
