The preparation for a scan depends on which part of the body will be scanned. When you schedule your appointment, our receptionist will explain what kind of procedure you will need to do prior to your scan.
It is important that you let us know if there is any chance of pregnancy , because CT scanning uses x-rays.
We also need to know any medications you are taking, and if you are a diabetic patient.
At the time of your scan, the radiographer will bring you into the CT scan room where you will lie down on a narrow, sliding couch. She will position the part of your body being scanned in the middle of a large doughnut shaped machine which holds the x-ray tube. She will leave the room during the scan, but is always in full view and communication with you through an observation window and microphone system in the adjoining room.
The scanner does not touch you , and you will not feel the x-rays. The table you lie on will move very slowly, and you will hear a very quiet noise as the camera moves.
Some procedures require an injection of a contrast medium, ( sometimes called dye), into a vein in your arm or hand. This helps to provide clearer images.
Once the scan is complete, you will have no restrictions on eating and drinking, and can go about your normal routine.
The radiologist, (specialized x-ray doctor), will carefully interpret your films, and a report will be sent to the ordering physician. You may then discuss the results with your doctor.
