I'm going to have a CT scan of my brain, and it's going to be in the morning. I usually have a cup of coffee a day. Do you think it's okay to drink coffee before a CT scan?
It's ok to have a cup of coffee in this instance given the CT is being done without intravenous contrast. Plus, no one will see what's in your stomach.
Intravenous contrast can cause some people to be nauseous and vomit during or shortly after the CT exam.
