It is always necessary to consult a doctor before the CT scan, because due to the radiation exposure, the CT scan can only be performed on the basis of a medical recommendation. The native test requires no special preparation. However, it is recommended that you do not consume food for 6 hours prior to the scan to allow for contrast administration, if necessary.
Prior to a CT scan with contrast agent, metformin medications for diabetes should be discontinued for 48 hours before the examination and resumed 48 hours afterwards.
The examination has no side effects, the patient does not feel anything. A contrast agent can very rarely cause a reaction, but the scan is not performed on anyone who is allergic to the contrast agent.
