Hi Judi,
I have had CT scans with and without 'contrast', the last one within the last couple of weeks. In this recent case the purpose of the scan was to help decide whether the pain in my chest was due to a blood clot or a chest infection which fortunately was the latter. A line is put into the patient, usually in the hand or arm. At an appropriate time as the scan progresses 'contrast' is fed through the line and the patient is likely to be warned that they may feel a sense of warmth though their hands and arms (As I did). The sensation does not last for long. The 'contrast' helps give better definition to the scan. Incidentally, MRI can also be given with or without 'contrast'.
Hope result is good.
