Overview
A CT scan takes X-ray images from many angles. It is quick and open, and often uses contrast dye that you drink or receive through an IV.
What to expect
- Fasting for a few hours if contrast is used
- A drink of oral contrast for some abdominal scans
- A warm flush when IV contrast is given — this is normal
- A scan lasting only a few minutes
Questions to ask
Do I need contrast, and why?
Have my kidney function results been checked?
How much radiation is involved, and is there a non-radiation alternative?
Have I had a reaction to contrast before?
In plain language, what is happening and why is it recommended now?
Plain language is your right. Ask again if the answer is technical.
What are my options, including waiting or doing nothing?
How will this change what I can do day to day, and for how long?
What should I do to prepare?
Who do I call with questions, and what number do I use after hours?
What would make you want to see me sooner?
This turns vague worry into a clear trigger for calling.
